​Microsoft Excel is an indispensable tool for data management, analysis, and financial tracking. However, encountering a corrupted Excel file can be a nightmare, especially if it contains crucial business or personal data. Fortunately, there are several methods to repair and recover a damaged Excel file.

Common Causes of Excel File Corruption

Unexpected power failures: If your system shuts down abruptly while editing an Excel file, corruption can occur.

Software crashes: A sudden crash of Excel or the operating system can result in an inaccessible file.

Malware and viruses: Some malicious software can damage or encrypt Excel files.

Bad sectors on storage devices: If the hard drive or SSD has bad sectors, files stored in those areas may become unreadable.

Large file size: Overloading Excel with extensive data, formulas, and macros can lead to corruption.

Improper file handling: Closing Excel improperly or frequent file transfers between different devices may cause data loss.

Methods to Repair a Corrupted Excel File

1. Use Excel’s Built-in ‘Open and Repair’ Feature

Microsoft Excel includes a repair function that attempts to fix corrupted files.

Open Excel.

Click File > Open.

Browse to the corrupted Excel file.

Click the drop-down arrow next to the Open button and select Open and Repair.

Choose Repair to recover as much data as possible.

If repair fails, select Extract Data to retrieve data without formatting.

2. Try Opening in Safe Mode

Excel Safe Mode disables add-ins and extensions that may be causing the corruption.

Press Win + R, type excel /safe, and press Enter.

Open the corrupted file and check if it loads correctly.

3. Change File Format

Sometimes, changing the file format can fix the issue.

Open Excel and go to File > Save As.

Save the file in a different format, such as .xls instead of .xlsx.

Reopen the saved file and then save it back as an .xlsx file.

4. Use a Previous Version (File History)

Windows maintains previous versions of files if File History or System Restore is enabled.

Right-click the corrupted file and select Properties.

Navigate to the Previous Versions tab.

Choose a version before the corruption occurred and click Restore.

5. Move the File to Another Location

Corruption may be caused by the current storage location.

Copy the file to another drive or cloud storage.

Try opening it from the new location.
