Method 3. Excel Corrupted Filr Repair via Changing File Extension of Excel Files

Older file formats (like .xls) may not support newer features or data types present in newer versions of Excel (.xlsx). When opened in a newer version, this can lead to errors or corruption.

Plus, sometimes, older files may contain bugs or issues that newer versions of Excel are not equipped to handle, resulting in crashes or corruption.

To solve the problem, you can:

On Windows:

• Open the File Explorer and switch to the top "View" tab.

• Then check the "File name extension" option from the "Show/hide" section.

  

• Switch to the top "Home" or "Computer" section and enable the "Rename" feature.

  

• Then change the corrupted Excel workbook from ".xls" to ".xlsx". Then press Enter.

On Mac:

• Go to Finder and select the corrupted Excel file.

• Select the top "File" > "Get Info". And expand the "Name & Entension" tab from the popup.

  
• Then change the ".xls" file extension to ".xlsx".

Method 4. Recover Excel File That Is Corrupted via Reseting Excel Calculation Option as Manual

Excel has two calculation modes: automatic and manual. If a file has errors when it calculates automatically, switching to manual mode can prevent Excel from trying to recalculate all formulas when opening the file, potentially avoiding crashes or freezes.

Besides, Some formulas may not calculate correctly in a corrupted file, causing errors. By changing it, you can reduce your reliance on these formulas.

Here's how to do that:

• On Excel workbook, go to "File" > "Options" > "Formulas".

• Choose the "Calculation options" and select "Manual" under it.

  

Method 5. Repair Damaged Excel File via Removing Flawed Add-ins from Excel

Some add-ins may not be compatible with the current version of Excel or with other installed add-ins, leading to file corruption. Moreover, add-ins can consume system resources. If they are malfunctioning, they might interfere with Excel's ability to read or write files correctly.

Thus, you can follow the steps below to remove the add-ins and repair Excel files:

• On the top-left corner of Excel workbook, select "File" > "Options".

• Choose "Add-ins" from the left menu and tap the "Go" button next to the bottom "Manage: Excel Add-ins" tab.

  

• Uncheck the add-ins and confirm the option by pressing "OK".

Here's how to make it:
