File Format and Extension of [filename] don’t Match in Excel File

Summary: The “File format and extension of [filename] don’t match. The file could be corrupted or unsafe” error message indicates that the Excel file you’re trying to open is unsupported, unsafe, or corrupted. Read this article to learn more about this error and how to fix this error. It also mentions an advanced Excel recovery tool to repair the corrupted Excel file and retrieve all its data in a few clicks.

You can encounter the “File format and extension of [filename] don’t match. The file could be corrupted or unsafe” error when the Excel application detects any issue with the file. This happens when you try to open an old version file format in a newer version or if the file is received from an unsafe destination. This can prevent you from opening the Excel file.

As indicated from the error message, this error occurs due to the following reasons:

• The file has incorrect file extension.
• The file is corrupted.

Now, let’s see how to resolve this Excel error.

Methods to Fix the “File format and extension of [filename] don’t match” Error

Try the following methods to troubleshoot the “File format and extension don’t match” error in Excel.

Method 1: Rename the Excel File

You can face the “File format and extension don’t match” issue if the file has incorrect extension. It can occur if the file extension has been altered or you’ve mistakenly saved the file with incorrect extension. To fix this, you can try renaming the Excel file with the correct file extension.  

Method 2: Check the Default Excel File Format

Different versions of Microsoft Excel use different default file formats. For example, .xls is the default file format of older versions (2003 and lower) of Excel, whereas .xlsx format is used by the newer versions (2007 and later). Opening the Excel file with an incompatible extension can cause the “File format and extension don’t match” issue. You can check the Excel version you are using and ensure it’s compatible with the Excel file you are trying to open.

Method 3: Change the Protected View Settings

You may receive the “File format and extension of excel don’t match” error if the Excel file is protected. You can check and try disabling the Protected View settings .

• Enable Protected View for Outlook attachments.

Method 4: Check and Provide the Excel File Permissions

Sometimes, you can get the error if you don’t have sufficient permissions to open the Excel file. This usually happens when you try to open the Excel file received from other sources. You can check and provide the desired permissions to fix the error. Here are the steps:

• Locate the affected Excel file, right-click on it, and select Properties.

• In the Properties window, click the Securities option and select Edit.

• In the Security window, under ‘Group or users name’, select the user names. Check the file permissions and make sure Full Control is enabled. If not, then click on the Add option.

• Click on the Advanced option in the Users, Computers, Service Accounts, or Groups window**.**

• Click the Find Now option. A list of all users and groups appears in the search field.

• Select “Everyone” from the list and then click OK.

• In the object names field, you will see ‘Everyone’. Click on OK.

• In the Permissions window, select “Everyone” and enable all options (Full Control, Modify, Read & Execute, Read, and Write) under Permissions for Everyone.

• Click Apply and then OK.

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 .

When this limit exceeds, you may encounter errors, such as “Too many different cell formats”. It can prevent you from inserting or modifying workbook rows or columns. Sometimes, it prevents you to copy and paste the content within the same or different workbooks.  This error may also occur due to various other reasons.

You can encounter the “Too many different cell formats” error due to the below reasons:

• Formatting is missing in the workbook.
• Size of your Excel file has increased due to excessive use of complex formatting (conditional formatting).
• Workbook contains a large number of merged cells.
• There are multiple built-in or custom cell styles.
• Excel workbook is corrupted.
• The unused styles are unexpectedly copied to new workbooks (when moving or copying a worksheet from one to another).
• Workbooks contain multiple worksheets with different cell formatting.
