Repair an Excel File
Reads your workbook leniently and re-saves it as a clean, standard .xlsx file — this can fix many structural issues (duplicate sheet names, minor XML corruption) but can't recover a file that's fundamentally unreadable. Runs entirely in your browser; nothing is uploaded.
How to use this tool
- Upload the Excel file you're having trouble with
- Review the fixes that were applied
- Download the repaired file
Common use cases
- Fixing a file another tool reports as corrupted
- Cleaning up a workbook with duplicate sheet names
- Getting a fresh, standard-format copy of an old file
