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.

Now, this is alarming, if you are heading a team or you have a bunch of people in your company who use Excel…

How to Repair Corrupt Pivot Table of MS Excel File?

Summary: If you are not able to perform any action on the Pivot Table of MS Excel file, it indicates Excel Pivot Table corruption. In such a case, you must repair the corrupt Pivot Table of MS Excel file by using an Excel repair software or manual troubleshooting steps discussed in this post.

MS Excel is equipped with several brilliant features and functions which make working with large volumes of data easy. In addition to helping users save data into well-organized cells and tables, the application helps users draw inferences from the data. Pivot Table is one such Excel feature that helps users extract the gist from a large number of rowed data. But often, the Pivot table may get corrupted and lead to unexpected errors or data loss.

Corrupt Pivot Tables can stop users from reopening previously saved Excel workbooks, raising the serious issue of data inaccessibility. Resolving such issues is an uphill task unless one gets to the actual root cause of the problem.

However, with Stellar Repair for Excel software, you can repair the corrupt Pivot table of MS Excel file while keeping the Excel file data, formatting, layout, etc. intact.

Excel Pivot Tables & Associated Problems

Pivot Tables in Microsoft Excel are created by applying an operation such as sorting, averaging, or summing to the data in certain tables. The results of the operation are saved as summarized data in other tables. Typically, working on the grouping of saved data, Pivot Tables are used in data processing and are found in data visualization programs, such as spreadsheets or business intelligence software.

Put simply, Pivot Tables in Excel allow you to extract the significance or the gist from a large, detailed data set by allowing you to slice-and-dice data, sort-and-filter data, or arrange it in any way you want.

Frequently Encountered Problems with Pivot Tables in MS Excel

Take a look at the most frequently encountered Pivot Table issues:

• You add new data into a pivot table but it doesn’t show up when you refresh
• Pivot Table contains Blanks instead of Zeros for fields that have no source data
• Automatic field names assigned by the Pivot Table can be inappropriate
• It doesn’t directly show the percentage of total
• Grouping one pivot table affects another
• Your number of formatting gets lost
• Refreshing a pivot table messes up column widths
• Field headings make no sense and add clutter

While some of the above problems seem minute and can easily be resolved using a few tweaks, bigger issues like unexpected Pivot Table error messages that an Excel throws can be troublesome.

Pivot Table Errors & Their Reasons

Excel users who have built new Pivot Tables in Excel often report the following errors when trying to reopen a previously saved workbook:

We found a problem with some content in . Do you want us to try to recover as much as we can? If you trust the source of this workbook, click Yes.

Naturally, users are prompted to click on ‘Yes’. But when they do, they get another error message saying:

Removed Part: /xl/pivotCache/pivotCacheDefinition1.xml part with XML error

(PivotTable cache) Load error. Line 2, column 0

Removed Feature: PivotTable report from /xl/pivotTables/pivotTable1.xml part (PivotTable view)

Such errors are indicative of the fact that the data within the Pivot Table still exists, but the table itself isn’t functioning anymore.

There could be two primary reasons behind such behavior:

• You’ve created the Pivot Table in an older version of Excel but are trying to open-refresh-save it through a newer Excel version
• The Pivot Table itself is corrupted

How to Repair the Pivot Table Quickly?

To solve the errors associated with Pivot Tables, you need to repair them. But Microsoft doesn’t offer any inbuilt technique or option to repair Pivot Tables. Thus, to fix the issue, you either need some sort of workaround or an Excel file repair software .

How to fix Pivot Table Field Name is not Valid error in Excel?

The Pivot Table field name is not valid error can occur while creating, modifying, or refreshing data fields in the pivot table. It can also appear when using VBA code to modify the pivot table. It usually occurs when there is an issue with the field name in a code or if there is a hidden or empty column in the pivot table. However, there could be many other reasons behind this error.

Why the “Pivot Table Field Name is not Valid” Error Occurs?

You can get the “Pivot Table field name not valid” error in Excel due to several reasons. Some possible causes are:

• Excel file is corrupted
• Damaged fields in the pivot table
• Pivot table is corrupted/damaged
• Hidden columns in the pivot table
• Macro (referring to the pivot table) is corrupted
• Preserve formatting option is enabled
• Missing or incorrect fields in the VBA code
• Issue with workbook.RefreshAll method syntax (if using)
• Pivot Table contains empty columns
• Header values or header column is missing in the Pivot Table
• Pivot table is created without headers
• Columns/rows are deleted from the Pivot Table

Methods to Fix Pivot Table Field Name is not Valid Error in Excel

You can get this error if you have selected the complete data sheet and then trying to create the Pivot Table. Make sure you choose only the data fields that you want to insert in the Pivot Table. If this is not the case, then follow the troubleshooting methods mentioned below.

Method 1: Check the Header Value in the Pivot Table

The “Pivot table field name is not valid” error can occur if you have not set up the pivot table correctly. All the columns having data in them should have header and header values. A pivot table without a header value can create issues. You can check the header and its value from the Formula bar. Change the header if the header value is too lengthy or if it contains special characters.

Method 2: Check and Change the Data Range in the Pivot Table

The “Pivot Table field name is not valid” can occur while modifying a field in Pivot Table. It usually occurs if you’re trying to add or modify the field by selecting an incorrect data range in the Create PivotTable dialog box. The “Create PivotTable“ feature helps define how data would be displayed within the pivot table.

Let’s take a scenario to understand this. Open the Excel file with PivotTable. Click on the fields (you want to add), go to the Insert option, and click PivotTable.

If you select an incorrect range, i.e. A1:E18, instead of correct range - “Expenses**!$A$3:Expenses!$A$4**,” you will immediately get the error message.

So, type the correct range under the Select a table or range option and click OK.

Method 3: Unhide Excel Columns/Rows

The error can also occur if some columns/rows of the Pivot Table’s data source are hidden. When you try to add a hidden column as a field in the PivotTable, the Excel application will fail to read the data of the hidden column. You can check and unhide the Excel columns by following these steps:

• Open the Excel file.

• Locate the hidden column number.

• Move your cursor on the hidden column number and right-click on the space between the columns. Click Unhide.

  

Method 4: Check and Delete Empty Excel Columns

Sometimes, you can get the “Pivot Table field name is not valid” error if you are trying to use an empty column as a field in your Pivot Table. Check the columns with no values in all cells. If found, then delete the empty columns. This method is ideal for small-size Excel files. However, for large-sized files, it is a time-consuming process.

Method 5: Unmerge the Column Header (If Merged)

The “Pivot Table field name is not valid” error can also occur due to merged column headers. The pivot table references headers to identify the data inside the rows or columns. The merged headers can sometimes create data inconsistencies. You can try unmerging the column headers to fix the issue. Follow these steps:

• In the Excel file, go to the Home

• Click the Merge & Center option and select Unmerge Cells from the dropdown.

  

Method 6: Disable the Background Refresh Option

If the “background refresh” option in the Excel file is enabled, it may also create issues with Pivot Table. The Excel updates all the pivot tables in the background even after a small change if the background refresh option is enabled. This may create issues if the Excel file is large with too many tables. You can try turning off the “background refresh” option in the Excel file to troubleshoot the issue. Here is how to do so:

• In the Excel file, go to the Data tab and then click Connections.

  

• In the Workbook Connectionsdialog box, click on the ‘Add’ dropdown to add the workbook (in which you need to modify the refresh settings).

  

• Once you have chosen the Excel file, click Properties.

  

• In the Connection Properties window, unselect the **”Enable background refresh”**option, select the “Refresh data when opening the file“, and click **OK.

  

  **

Method 7: Check the VBA Code

The error can also occur when working with PivotTable using VBA code in Excel. Some Excel users reported this error on forums as run-time error 1004: The PivotTable field name is not valid. This error usually occurs when there are issues in the VBA code, affecting the PivotTable data source or field references. You can check field names referring to PivotTable or Workbook.RefreshAll function syntax and other errors in the code.

Method 8: Repair your Excel File

One of the reasons behind the “Pivot Table field name is not valid” error is corruption in the Excel file, containing the Pivot Table. You can repair your Excel file using Microsoft built-in utility - Open and Repair. Here’s how to use this utility:

• In Excel, navigate to File > Open.

• Click Browse to choose the affected workbook.

• The Open dialog box will appear. Click on the corrupted file.

• Click the arrow next to the Openbutton and then select Open and Repair.

• You will see a dialog box with three buttons - Repair, Extract Data, and Cancel.

  

• Click on the Repair button to recover as much of the data as possible.

• After repair, a message is displayed. Click Close.

Method 9: Use a Professional Excel Repair Tool
