Repair a Damaged Excel File

Try to get your data back from an XLSX or XLS file that Excel says is corrupt.

About Repair Excel

Repair Excel workbooks that stopped opening after a failed download, a crash while saving, a faulty USB stick or an email attachment that arrived broken. Upload the XLSX or XLS file and we try to read what's still intact and save it into a file you can open again. To look through the recovered data without Excel, open it in Office Viewer.

How much comes back depends on the damage. A file that was cut short or partly overwritten may lose some content, and formatting, charts or pictures may not survive even when the numbers do. Before anything else, check for a backup or an earlier version in OneDrive, Google Drive or your email, since an undamaged copy always beats a repaired one. With an older copy in hand, Compare Excel can show where it and the repaired file differ.

FAQ

Repair Excel: questions and answers

Can Repair Excel fix every broken file?
No tool can promise that. If parts of the file were overwritten or never saved, that data is gone. We recover whatever can still be read.
What should I try before I repair Excel files online?
Look for an earlier copy first, because OneDrive and Google Drive keep version history. Excel's own Open and Repair command is also worth a try. If none of that works, upload the file here.
Will formatting and charts be recovered?
Sometimes, but the priority is your data. Values and text are the most likely to come back, while charts, pictures and complex formatting may be lost.
Is it free to repair an Excel file online?
Visitors can try 2 tasks and free accounts get 2 a day, for files up to 50 MB. VIP removes the daily cap and takes files up to 1 GB.
Is my damaged file kept private?
Yes. It's uploaded over HTTPS, processed in an isolated process and deleted after one hour. We don't look at its contents.
