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.
Privacy & processing: Runs entirely in your browser — your file is never uploaded to a server.
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
Limitations
Only works on a file it can already open — if a workbook is too corrupted to open, this tool can't recover it. It doesn't touch blank rows or merged cells (use Clean Excel Data for that).
FAQ
Will this fix a corrupted file that won't open at all?
No — Excel File Repair can only work with a file it can read; if the file is too corrupted to open, this tool can't recover it.
Does it remove blank rows or merged cells inside a sheet?
No — that's handled by Clean Excel Data, not File Repair, which only acts at the sheet level (empty sheets, name conflicts).
What counts as an "empty" sheet?
A sheet with no cell data at all — not one that merely has some blank rows or columns within otherwise real data.
