How to fix a corrupt Excel file?
There are several ways to fix a corrupt Excel file, depending on the severity of the corruption.
Method 1: Open Excel in Safe Mode
One way to recover a corrupt Excel file is to open Excel in Safe Mode. This allows Excel to open without any add-ins, which can sometimes cause issues with file opening. To open Excel in Safe Mode, follow these steps:
- Press the Windows key + R to open the Run dialog box.
- Type “excel.exe /safe” and press Enter.
- Excel will open in Safe Mode. Try opening the corrupt file again.
If the file opens successfully in Safe Mode, you can try disabling any add-ins that may be causing the issue. To disable add-ins, follow these steps:
- Click on File, then Options.
- Select Add-Ins from the left-hand menu.
- In the Manage box at the bottom of the window, select Excel Add-Ins and click Go.
- Uncheck any add-ins that are currently enabled and click OK.
- Close Excel and reopen it normally.
Method 2: Repair the File
If opening the file in Safe Mode does not work, you can try repairing the file. To repair a corrupt Excel file, follow these steps:
- Open Excel and click on File, then Open.
- Select the corrupt file and click on the arrow next to the Open button.
- Select Open and Repair from the dropdown menu.
- Select either Repair or Extract Data depending on how severely the file is corrupted.
- Click OK and wait for Excel to repair the file. The repaired file will be saved with a different name.
Method 3: Use a Third-party Tool
