Repair an Excel File Online
When Excel reports that a workbook is corrupt or unreadable, this tool runs a browser-only diagnostic on the file's XLSX structure and exports the readable sheet values into a clean new workbook. You can repair an Excel file online for free with no upload - everything stays on your device.
What Browser-Only Repair Can and Cannot Do
Honesty matters here: a privacy-first, browser-only repair tool cannot fix every kind of corruption. It works best when the XLSX ZIP package is still readable and the underlying cell values can be extracted.
- Can - inspect structure, list readable sheets, and export recoverable cell values to a fresh .xlsx.
- Cannot - recover encrypted (password-to-open) files, or restore complex formatting, charts, pivot tables, and macros.
If repair does not fully restore your file, try Excel Recovery or Corrupt Excel Repair, and read our guide to repairing an Excel file.
How This Compares to Paid Excel Repair Tools
Most Excel repair services follow one of two patterns: a desktop program that charges per file (often around $10-40 for a single recovery), or an online service that uploads your file, shows a blurred or partial preview, and asks for payment before releasing the recovered data. Enterprise tools also cap their free tier at roughly 2 MB or gate downloads behind a sign-in.
- Free, in full - recoverable values download without payment, watermark, or preview paywall.
- No upload - the file is inspected in your browser; nothing is sent to a server, so confidential workbooks stay private.
- No size gate or signup - process any file your browser can open, as many times as you need.
The trade-off is honest scope: paid desktop tools may reconstruct deeper structural damage than a browser can. For the common case - a workbook that Excel won't open but whose data is still intact inside - this recovers it for free, in seconds.
