Resolve Compile Error in Hidden Module in Excel: Causes & Solutions

The hidden module in Excel refers to a container with VBA codes, custom queries, and complex macros. The compile error in a hidden (protected) module in the Excel worksheet usually occurs when doing different activities on a macro-enabled sheet, such as merging .xls files. The error can result in macros execution failure. You need to quickly resolve this compile error to restore full functionality of the VBA code. Below, we’ll be discussing the solutions to fix this Excel error. But before that, let’s see why this error occurs.

You may encounter the Compile error in hidden module due to one of the following reasons:

• The code in the workbook is not compatible with the Excel application.
• Manual queries created in a previous version are no longer compatible with your current version of Excel.
• Missing references.
• Invalid .exe files (control information cache files) are automatically created with ActiveX control insertion in Excel file.
• Protected module is corrupted.
• The workbook with hidden module is damaged or corrupted.
• Incompatible add-ins.
• Incompatible Excel file version.
• The module is protected or password-protected.
• Missing or corrupted mscomctl.ocx file.

Excel can throw the compile error while compiling the code that exists in the protected module. So, first check the error and identify the hidden module that is creating the issue. You can unprotect the module. Also, ensure that you have permission to access the VBA code in the module. If the error still exists, follow the below troubleshooting methods.

Method 1: Re-register ActiveX Control Files or mscomctl.ocx Files

You can get the compile error in the Excel file, containing the VBA code related to ActiveX controls or OCX files. The ActiveX control files and OCX files (mscomctl.ocx files) are the components of Microsoft’s standard controls library. The compile error in the hidden module can occur if these files are missing. In this case, you can use the Regsvr32 tool to re-register the OCX files. The Regsvr32  is a command-line utility to register and unregister OLE controls in the Windows registry.

Method 2: Delete .exd Files

 The .exd files are temporary files created by Excel when inserting ActiveX controls objects. These temporary files can lead to a compile error if they are corrupted. So, if this issue has occurred, particularly in the Excel file containing ActiveX controls, then deleting .exd files might fix the issue. To delete the .exd file, follow the below steps:

• First, open the Run window by pressing the Windows+R keys.

• In the Run window, type %appdata%.

• In the Roaming window, click on the Microsoft option.

• Under Microsoft, you will see a list of folders. Search and click on Forms.
• Right-click on a file with .exd extension and select Delete.
• Once you delete the .exd files, restart your Excel application.

Method 3: Rollback the Office Updates

MS Office updates or upgrades may also cause the compile error in hidden module in Excel. If the error has occurred after downloading the recent Microsoft Office updates, try reverting to the previous version or uninstalling the recent updates to fix the issue.

Method 4: Unselect Missing References

The compile error in hidden module determine path in Excel can also occur if your file contains a reference to object library/type library, which is labelled as Missing. You can locate, check, and uncheck the references marked as ‘Missing’ to fix the issue. Here are the steps:

• Open your Excel and press Alt + F11 keys.
• The Visual Basic Editor is displayed.

• Go to the Tools option and then click References.

• In the References-VBAProject window, under Available References, search and unselect the references starting as “Missing”.

• Click OK.

Method 5: Check the Code in Module

The compile error in hidden module can occur if there are issues in the code within the module. The problems include incorrect or missing syntaxes, missing parameters/references, or the code contains incompatible functions or a wrong name of the object. You can check and fix these issues in the code by opening the VBA editor.

Method 6: Check and Remove Add-ins

In Excel, the compile error in macro-enabled files can also occur due to incompatible add-ins. You can check and disable the add-ins in Excel using the below steps:

• First, open the Run window and type excel /safe and then click OK. The Excel application will open in safe mode.
• Now try to open the affected Excel file. If it opens without the error, then check and remove the latest installed Excel add-ins.
• Navigate to the File option and then select Options.
• In the Excel Options window, click Add-ins.

• Under Add-ins, search and select the latest add-ins, and then click on Go.
• In the Add-ins window, uncheck the add-ins and then click OK.

• Restart Excel and then check if the error is fixed or not.

Method 7: Repair the Corrupt Excel File

Corruption in the Excel file can affect the macros in the hidden module, which may result in the compile error. In such a case, you can try repairing the Excel file using Microsoft’s inbuilt utility -Open and Repair. To use this tool, follow these steps:

• Open your Excel application.
• Click the File tab and then click Open.
• Click Browse to select the affected workbook.
• The Open dialog box will appear. Click on the corrupted file.
• Click the arrow next to the Open button and then Open and Repair.

How to Fix a Corrupted .xls File? The Everything Guide

Undoubtedly, Excel is so powerful that it can help you to process, analysis, and store data, in masses.

That’s the reason it has been there for years and helping this world in data.

But…

With all those powers comes some nasty problems which no Excel users like to face. Can you guess what I’m talking about?

Think about a Corrupted Excel File. Nightmare? Isn’t it?

And do you remember that last time when you have opened a workbook and you got a message that this workbook is might corrupt?

The TRUTH is, this is something which you cannot avoid, but, you can prepare yourself in the best way and deal with it like a PRO.

So today, in this post, I’d like to share with you to everything you need to know about a corrupt Excel file (.xls), why it happens, how to fix it like a PRO, and much more.

…let’s get started.

Note: In this post, we’ll be covering the .xls version (which is the extension for the file which is created in Excel 2007 or the earlier versions) and if you want to know about the new version, here’s the quick fix for that.

Why My Excel File Got Corrupted?

There can be one or multiple reasons for an Excel file to get corrupted. Below I have detailed about some of the major of them.

1. Large Excel File

You can store data in a workbook the way you want but sometimes using excessive thing can make an Excel file bigger in size.

And that kind of data files can crash at any point in time. Here are a few things which make the Excel files heavy, like

• Conditional Formatting.
• Colors formatting.
• Using merged cells in place of text alignment.
• Volatile functions: Formulae that iterate every time you open or change a cell value; OFFSET, NOW.
• Using a complete column or row as a reference than the data set range.
• Using complex formulas; VLOOKUP in place of Index/Match, Nested If in place of MAXIFS, MINIFS.
• Calculations or reference across workbooks.

2. Abrupt System Shutdown

Shutting down the system without following the procedure can corrupt your data file.

This shut down can be due to a power failure or any other unexpected technical challenges.

So it is always important to follow the procedures and shut down your system properly to avoid data losses.

3. Infected Excel File (Virus Attack)

This is the most common and obvious reason for Excel file corruption.

Although we always keep our system safe using various Antiviruses, still there is always a probability of virus attacks and loss of important files.

It is always advised to use a safe and strong antivirus compatible with your system requirements.

What are the Signs to Know When an Excel File is Corrupted?

In this section, we will discuss what are the signs which you can get when an Excel file is corrupted, let’s dig into it.

1. The File is Corrupt and Cannot Be Opened

This is one of the most common messages you can see when your workbook is corrupted.

But there is also a chance that it is just because of the version compatibility where you have a .xls file but you are using the latest version of Excel check out this detailed post by Priyanka

2. We Found a Problem with some Content in this File…

There’s another error message which you can get while opening a file:

We Found a Problem with some content in Do you want us to recover as much as we can? If you trust the source of this workbook, click yes.

There are a lot of applications out there (I think almost every) which exports the data as a .xls format. Those files have a greater chance of having this kind of error.

3. “Filename.xls” cannot be accessed

There can also be a situation where you get the error:

“Filename.xls” cannot be accessed. The file may be corrupted, located on a server that is not responding.

Well, this message is a bit misleading.

You won’t be able to decide that your file is actually corrupted or just not on the location.

My Excel File Got Corrupted, now What Should I Do?

There are many ways to recover the data from the corrupt excel files. But before you start, it is always advised to create a copy of the corrupted file.

You can save a lot of time with Stellar Repair for Excel, which make data recovery just with few clicks.

But before you go for a data recovery software, let’s try out some manual steps which can help.

When a workbook get corrupted the first thing comes to the mind is to recover data from it…

…and you what there’s a simple option there in the Excel which you can use to do this. Below are the steps you need to follow:

• First of all, open the Excel and click on the office icon.

• After that, go to the “Open” and select the file which is corrupted.

• Now, click on the open drop-down and select “Open and Repair”.

• At this point, you have two options:

1. Repair File
2. Extract Data

Let’s get into both of these options one by one…

1. Repair File

This option helps you to repair the file and the moment you click on it it takes a few seconds afterward and shows you the result with a message box and also provide you a log file.

And once it is done with repairing, you’ll get your file opened and you can save that file as a new copy.

Yes, that’s it.

2. Extract Data

If somehow you aren’t able to get your file repaired, you can also extract data from that file using “Extract Data” option.

Even in this option, you can get data in two ways.

1. As Values
2. With Formulas

In the first option, Excel simply extracts data as value ignoring all the formulas driving those value (which is the best way if you just need to have that data back ).

But in the second option, Excel tries to recover the formulas as much as possible.

Check out this smart technique by Jyoti which you can use it you aren’t able to recover data from the file.

Preventions to Not to have any Excel File Go Corrupt in Future

Future is fragile, what I’m trying to say is the more you work in Excel and process data there could be a chance that your workbook goes corrupt.

If there’s no security then what an EXCEL POWER user should do?

Well, there are few things which you can do or take care of while working with Excel so that you won’t have to worry about corruption of Excel workbooks.

Let’s see what you can do…

1. Change Recalculation Option

Now here’s the thing when you work with a hell lot of data, there a common thing that you gotta using formulas. Right?

But, the thing these formulas are something which makes your Excel file slows down sometimes make them go corrupt.

There’s one small tweak you can do in your workbook is change the calculation method.

Now with the manual calculation, you just need to whenever you open your file it won’t recalculate all the formulas.

And when you update your data you can simply click on the “Calculate Now” and it will calculate all the formulas again.

Quick Tip: Beware of Volatile Functions and use them with caution as recalculates them every time you change something in the worksheet.

2. Use VBA Codes Instead of Formulas

Now, this is what I do when I need to use complex formulas in a workbook.

Here’s how you can do this: Let’s say you have a formula in the cell A1, like below, which calculates the age.

=“You age is “& DATEDIF(Date-of-Birth,TODAY(),”y”) &” Year(s), “& DATEDIF(Date-of-Birth,TODAY(),”ym”)& “ Month(s) & “& DATEDIF(Date-of-Birth,TODAY(),”md”)& “ Day(s).”

Now, instead of simply entering it into the cell A1 which I would write a macro code which inserts this formula into the cell A1 and then convert it into the a value.

Here’s the code:

Sub CalculateAge()
Range(“B1”).Value = _
“=””Your age is “”” & _
“&DATEDIF(A1,TODAY(),””y””)” & _
“&”” Year(s), “”” & _
“&DATEDIF(A1,TODAY(),””ym””)” & _
“&”” Month(s), and “”” & _
“&DATEDIF(A1,TODAY(),””md””)” & _
“&”” Days(s).”””
Range(“B1”) = Range(“B1”).Value
End Sub

Note: To write these code you need to have basic understading of VBA (make sure check out this guide for this).

3. Use a File Recovery Application

Recently we asked a quick question to our readers on ExcelChamps that if they have ever faced a situation where they got a corruption message in Excel.

You’ll be astonied to hear that 50% percent of the people said “YES” they faced this thing in the past.

How to Fix Excel Formulas Not Working Properly | Step-by-Step Guide

Summary: Excel formulas sometimes fail to function correctly and even return an error. This article explains what you might be doing wrong that prevents Excel formulas from working properly and solutions to resolve the issue. If your formulas have disappeared from the Excel spreadsheet and you are having trouble recovering them, you can use an Excel repair tool to recover the formulas.

When working with Excel formulas, situations may arise when the formula doesn’t calculate or update automatically. Or, you may receive errors by clicking on a formula.

Problems Causing the ‘Excel Formulas not Working Properly’ Issue and Solutions

Let’s check out the possible reasons that cause Excel formulas to work properly and solutions to resolve the issue.

Problem 1 – Switching Automatic to Manual Calculation Mode

Automatic and manual are the two modes of calculation in Microsoft Excel.

By default, Excel is set to automatic calculation mode. Everything is recalculated automatically when any changes are made in a worksheet in this mode. You may switch from automatic to manual mode to disable the recalculation of formulas, particularly when working with a large Excel file with too many formulas.

Excel will not calculate automatically when set to manual calculation mode. And this may make you think that the Excel formula is not working properly.

Solution – Change Calculation Mode from Manual to Automatic

To do so, perform these steps:

• Click on the column with problematic formulas.
• Go to the Formulas tab, click the Calculation Options drop-down, and select Automatic.

Problem 2 – Missing or Mismatched Parentheses

It’s easy to miss or incorrectly place parentheses or include extra parentheses in a complex formula. If a parenthesis is missing or mismatched and you click Enter after entering a formula, Excel displays a message window suggesting to fix the issue (refer to the screenshot below).

Clicking ‘Yes’ might help fix the issue. But Excel might not fix the parentheses properly, as it tends to add the missing parentheses at the end of a formula which won’t always be the case.

Solution – Check for Visual Cues When Typing or Editing a Formula with Parentheses

When typing a formula or editing one, Excel provides visual cues to determine if there’s an issue with the parentheses inserted in a formula. Checking for these visual cues can help you fix missing/mismatched parentheses.

• Excel helps identify parenthesis pairs by highlighting them in different colors. For instance, the pair of parenthesis outside is black.
• Excel does not make the opening parentheses bold. So, if you’ve inserted the last closing parentheses in a formula, you can determine if your parentheses are mismatched.
• Excel helps identify parentheses pairs by highlighting and formatting them with the same color once you cross over them.

Problem 3 – Formatting Cells in an Excel Formula

When adding a number in an Excel formula, don’t add any decimal separator or special characters like $ or €. You may use a comma to separate a function’s argument in an Excel formula or use a currency sign like $ or € as part of cell references. Formatting the numbers may prevent the formula from functioning correctly.

Solution – Use Format Cells Option for Formatting

Use Format Cells instead of using a comma or currency signs for formatting a number in the formula. For instance, rather than entering a value of $10,000 in your formula, insert 10000, and click the ‘Ctrl+1’ keys together to open the Format Cells dialog box.

Problem 4 – Formatting Numbers as Text

Numbers are displayed as left-aligned in a sheet in a worksheet, and text formatted numbers are right-aligned in cells. Excel considers numbers formatted as text to be text strings. Thus, it leaves those numbers out of calculations. As a result, a formula won’t work as intended. For example, in the following screenshot, you can see that the SUM formula works correctly for normal numbers. But, when the SUM formula is applied to numbers formatted as text, the formula doesn’t return the correct value.

Sometimes, you may also see an apostrophe in the cells or green triangles in the top-left corner of all the cells when numbers in those cells are formatted as Text.

Solution – Do Not Format Numbers as Text

To fix the issue, do the following:

• Select the cells with numbers stored as text, right-click on them, and click Format Cells.
• From the Format Cells window, click on Number and then press OK.

Problem 5 – Double Quotes to Enclose Numbers

Avoid enclosing numbers in a formula in double-quotes, as the numbers are interpreted as a string value.

Meaning if you enter a formula like =IF(A1>B1, “1”), Excel will consider the output one as a string and not a number. So, you won’t be able to use 1’s in calculations.

Solution – Don’t Enclose Numbers in Double Quotes

Remove any double quotes around a number in your formula unless you want that number to be treated as text. For example, you can write the formula mentioned above as “1” =IF(A1>B1, 1).

Problem 6 – Extra Space at Beginning of the Formula

When entering a formula, you may end up adding an extra space before the equal (=) sign. You may also add an apostrophe (‘) in the formula at times. As a result, the calculation won’t be performed and may return an error. This usually happens when you use a formula copied from the web.

Solution – Remove Extra Space from the Formula

The fix to this issue is pretty simple. You need to look for extra space before the equal sign and remove it. Also, ensure there is an additional apostrophe added in the formula.

Other Things to Consider to Fix the ‘Excel Formulas not Working Properly’ Issue

• If your Excel formula is not showing the result as intended, see this blog .
• When you refer to other worksheets with spaces or any non-alphabetical character in their names, enclose the names in ‘single quotation marks’. For example, an external 5reference to cell A2 in a sheet named Data enclose the name in single quotes: ‘Data’!A1.
• You may see the formula instead of the result if you have accidentally clicked the ‘Show Formulas’ option. So, click on the problematic cell, click on the Formula tab, and then click Show Formulas.
• If you’re getting an error “Excel found a problem with one or more formula references in this worksheet”, find solutions to fix the error here .

[Fixed] Excel Cannot Open the File Because the File Format or File Extension Is Not Valid

When opening an older version of an Excel file in a newer version, you may encounter the “Excel cannot open the file because the extension is not valid” error. This happens if you have accidentally renamed the file with a different file format or an incorrect file extension. Also, you may get the ‘Excel cannot open the file’ error if the file has become unreadable or corrupted.

This is how the complete Excel error message looks like:

“Excel cannot open the file filename.xlsx because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.”

How to Fix the ‘Excel Cannot Open the File Because the File Format or Extension Is Not Valid’ Error?

Try any of these workarounds to fix the error and regain access to your Excel file data:

Workaround 1 – Change the Default File Format

By default, an Excel file is saved in .xlsx or .xls file format. Trying to open the file with a different or incorrect extension may cause the ‘Excel cannot open the file because the extension is not valid’ error. To fix the error, try changing the Excel default file format by following these steps:

Note: Take a backup of the Excel file that you cannot open and try the steps on the backup copy.

• In Excel 2010 and newer versions, click on the File menu.

Note: For Excel 2007 and earlier versions, click on the Office button.

• On the left panel, click on Options. 
• In ‘Excel Options’ window, under Save workbooks section, click on the Save files in this file format: drop-down. Select a file format (i.e., the one supported by your Excel version).

• Click OK.

Check if you can open your Excel file. If not, try the next workaround.

Workaround 2 – Edit the Excel File Permissions

You may receive the ‘Excel file format or file extension is not valid’ error if you lack sufficient permissions to open the file. Usually this happens when you try to open an Excel file received from some other user. Follow these steps to change the file permissions and see if it fixes the problem:

• Right-click on the file that won’t open and click Properties.
• In the file properties dialog box, click the Security tab and then hit the Edit button.

• When the file’s permissions dialog box appears, click on the Add button.

• Click on the Advanced button from the ‘Select Users or Groups’ window.

• Select Find Now. A list of all users and groups will get displayed in a search results box. Choose Everyone group from the list and hit OK.

• You can see the ‘Everyone’ group in the ‘Enter the object names to select’ textbox. Click OK once again to return to the file’s permission dialog box.

• Click Everyone from the Group or user names: box and check all the checkboxes under Allow.

• Click on Apply and then OK.

Now try to open the Excel file. If you’re still getting the Excel file cannot open error, use the following workaround.

Workaround 3 – Recover Unsaved Workbook

If the ‘Excel file extension not valid error’ occurs when attempting to open an unsaved workbook, do the following to recover the unsaved workbook:

• In Excel, click File. 
• From the Info screen, under Manage Versions, click Recover Unsaved Workbooks.

Excel will list any unsaved files. Try opening the file and save it. If this doesn’t work, skip to the next workaround.

Workaround 4 – Repair the Workbook

If none of the above workarounds has worked for you, chances are that the Excel file has become corrupted. Try to repair the file using the Excel inbuilt ‘Open and Repair’ utility by following these steps:

• In your Excel application, click on File > Open.
• In the ‘Open’ dialog box that pops-up, select the Excel file you want to repair and click the arrow next to the Open button.

• From the dropdown list, select Open and Repair.

• Excel will ask you to attempt to repair the file or extract data from it. Click Repair to retrieve maximum data. If the Repair option fails, click on Extract Data to recover the data without formulas and values.

If the ‘Open and Repair’ utility doesn’t help fix the corrupted file and/or recover the data, use an Excel repair tool  such as Stellar Repair for Excel to regain access to your file and its data.  

Stellar Repair for Excel software can help repair severely corrupted XLS and XLSX files. Also, it helps recover all the file components, including tables, pivot tables, cell comments, charts, chart sheets, images, formulas, etc., without impacting the original structure of the Excel file.

How to Repair Excel Document on a Flash Drive

Summary: Microsoft Excel files are stored on flash drives if they need to be transferred between systems or if they need to be backed up. But sometimes unforeseen issues can corrupt the Excel sheets stored on flash drives. When that happens, it can be an arduous task to repair Excel documents on a flash drive. Through this post let us try to understand the reasons why Excel sheets stored on flash drives can get corrupted and how users can resolve them easily.

In this digital age, we all work with computers, files, and documents. Flash drives or USBs are common ways of storing data in an external place. Be it for a meeting or for a party playlist, these devices come handy when one wants to transfer data or access the files stored elsewhere.

You may need to access your data from another location. That’s when a USB flash drive might come in handy. And, that’s exactly why Excel sheets too end up on flash drives; either that or for backup purposes. However, there are many instances where an Excel file stored in a USB gets corrupted when one tries to access the file. The error message you get while trying to open the Excel file would be a great clue for figuring out the exact reason behind corruption.

This blog will provide insights into what are the reasons for the corruption of a USB and how the users can repair Excel on flash drive that has been corrupted.

Reasons for USB inaccessibility

Sometimes flash drives or USBs can become unresponsive due to numerous reasons. There are two types of corruption – logical and physical. Physical corruptions occur due to broken stems and connectors, broken circuits, NAND gate, not recognised, RAW, need to format, not accessible, and dead drives (no power supply).

One of the main reasons behind such an error could be that the USB drive has been infected by some virus. This can affect any file – not only the ones which are there in the USB drive but also the ones which are there in the PC/Laptop where you connect the USB drive. It is recommended that you scan the USB drive with reliable antivirus software to detect viruses.

There can be various other reasons that may make your USB corrupt or unresponsive. But there are very slim chances that you will be able to recover a flash drive that has physical damage. However, you can try to run the check disk on the USB drive to fix the drive. We will be discussing this as you read on.

Recovery Methods for Corrupted Flash Drives

There are 3 tried and tested recovery methods. Try them and see which one works out for you.

1. Restoring Excel Files from Windows backup

Step-by-step process for restoring your older Excel files:

• Connect your USB drive
• Go to “My Computer”->USB Drive->Check if the file exists
• Right click on the excel file and click on the restore previous versions

• You will now see a list of older versions which were created
• Select one the backups and click on “restore”

2. Using Command Line to Recover Excel Files

• Connect your USB Flash drive
• Open “Run” (press Windows+R) and then open “cmd”

• Type “attrib -h -r -s /s /d (USB Drive Letter):\*.*” where the (USB Drive Letter) is the drive letter you can find using “My Computer”
• Once this has been completed, Windows will start repairing your files
• After the process gets over, try accessing the excel file to see if the data has been recovered

3. Running a “Check Disk” on flash drives

Follow the below steps while the USB flash drive has been plugged into your computer:

• Open “Run” and then open “cmd”
• Type in “chkdsk /X /f (USB Drive Letter)” where the “(USB Drive Letter)” is the letter of the corrupted USB Drive. You can get this letter easily from the “My Computer”.
