About XLSX
Workbook Audit scans your file for the problems Excel never warns you about: broken formulas pointing at deleted cells, sheets someone hid three years ago, links to files nobody can find anymore, numbers stored as text that quietly break your totals.
You get the exact cell address for every issue. No hunting through a 400-row sheet to find the one formula that's wrong.
The scan runs entirely in your browser. Your file is never uploaded, never stored, never sent anywhere. Open the network tab and watch: zero requests. That's not a privacy policy, it's how the tool is built.
Scanning is free and unlimited. No account, no email, no upload cap. Pro is $9 a month and does the tedious part for you: unhide every hidden sheet at once, strip out every external link, convert text-back-to-numbers in bulk, and export the whole report.
Works with .xls, .xlsx, and .xlsm. One-click fixes are .xlsx and .xlsm
