Why Do Excel Files Become Corrupted?

Understanding the cause helps prevent future damage. Excel files may become corrupted due to:

  • Unexpected system shutdown or crash

  • Power interruption during editing

  • Malware or ransomware attacks

  • Faulty storage devices (USB, HDD, SSD)

  • Excel freezing while saving

  • File format conversion problems (.xls to .xlsx)

If the file won’t open or shows random characters, error messages, or missing data—don’t panic. Try the recovery steps below.

Method 1: Use Excel’s Built-In Repair Feature

Microsoft Excel includes a built-in recovery tool designed to fix corrupted workbooks.

Steps to repair the file:

  1. Open Microsoft Excel (not the corrupted file).

  2. Click File > Open.

  3. Select the corrupted Excel file.

  4. Instead of clicking Open, click the arrow next to it and choose Open and Repair.

  5. Select Repair when prompted.

If Repair fails, repeat and select Extract Data instead. This attempts to recover values and formulas even if formatting is lost.

Method 2: Recover From Temporary Backup Files

Excel automatically saves temporary versions of files. You may be able to restore a recent working copy.

Option A: AutoRecover Backup

  1. Open Excel and go to File > Options.

  2. Select Save.

  3. Note the AutoRecover file location.

  4. Paste that path into File Explorer.

  5. Look for files ending in .xlsx or .xlsb.

Option B: Windows Previous Versions

  1. Right-click the corrupted file.

  2. Select Properties.

  3. Click the Previous Versions tab.

  4. Restore an earlier version (if available).

📌 Windows File History must be enabled for this method.

Method 3: Open the File in a Different Program

Sometimes Excel cannot read the file properly, but another spreadsheet program can.

Try opening the corrupted file in:

  • Google Sheets

  • LibreOffice Calc (free & open-source)

  • WPS Office

To try Google Sheets:

  1. Go to Google Drive

  2. Click New > File Upload

  3. Upload your corrupted Excel file

  4. Right-click it > Open with Google Sheets

Sheets may strip complex formatting, but can still retrieve your content.

Method 4: Use Excel Safe Mode

Safe Mode disables add-ins that may prevent a file from opening.

Open Excel in Safe Mode:

  1. Press Windows + R

  2. Type:

    excel /safe

  3. Press Enter

  4. Try reopening your corrupted file

Method 5: Change Excel File Extension

If your file was saved incorrectly, renaming the extension may work.

Try converting the file:

  1. Right-click the file > Rename

  2. Change .xlsx → .xls
    (or .xls → .xlsx)

  3. Try reopening in Excel

Alternatively, compress and extract it:

  1. Right-click file > Send to > Compressed (zipped) folder

  2. Open the zip folder

  3. Try opening extracted contents

Method 6: Recover From Temporary Folder

Sometimes Excel temp-saves your file in Windows’ temp directory.

Search temp files:

  1. Press Windows + R

  2. Type:

    %temp%

  3. Press Enter

  4. Sort by date modified

  5. Look for files like:
    ~Excel##.tmp or similar

Rename them to .xlsx and try opening in Excel.

Method 7: Use Free Online Recovery Tools

If Microsoft’s built-in tools fail, try online repair utilities. Popular free options include:

Tips to Prevent Excel File Corruption

Once your file is recovered, protect it from future damage:

  • Always save to a local drive first, then cloud-sync

  • Enable AutoSave and AutoRecover in Excel

  • Avoid force-closing Excel or powering off during saving

  • Use OneDrive, Google Drive, Dropbox for backup

  • Keep your PC free of malware

  • Avoid excessively large or macro-heavy workbooks
