Fix broken links in an Excel file — free.

What counts as a broken link

This tool fixes one specific thing: links to other workbooks. A formula like ='[1]Budget.xlsx'!B4 reaches into a second file for its value. The moment that other file is moved, renamed, or deleted, Excel can’t follow the link — the cell keeps showing the last value it cached and quietly never updates again. We find those references and freeze each one to that last saved value, so the number stays put and the file no longer depends on a file you don’t have.

Your original file is never changed

The fix is always a separate copy. We read your upload in memory, build a repaired workbook, and give it to you as a download — your original is never modified and nothing from it is stored. Freezing a link replaces the broken formula with the value Excel last saved for it, so those cells will no longer try to auto-update from the missing file. We say exactly which cells were frozen.

What we won’t guess at

If a broken link points at a large range or a dynamic formula that can’t be reduced to a single saved value safely, we leave it alone rather than risk a wrong number. You’ll see it listed as left as-is.
