CLEANSHEET

Excel files quietly carry what you did not mean to send: the formulas behind your prices, tabs you only hid, the raw rows behind a pivot table, cell comments, and links that spell out folders on your computer. CLEANSHEET strips all of it, in your browser, with nothing uploaded.

What sanitizing does, precisely:

  1. Formulas are replaced by the values they currently show, so the numbers stay and the math behind them is gone.
  2. Hidden and VeryHidden worksheets are deleted outright, not just re-hidden.
  3. Pivot tables and their cached data are removed, so no one can drill back into the raw source rows.
  4. Cell comments and notes are stripped.
  5. Links to other files (and the folder paths they reveal) are removed.

CLEANSHEET runs entirely on your device. Nothing about your spreadsheet is uploaded anywhere. The sanitized copy is a new file, so your original is never changed. Sanitizing does its best to keep the visible content and layout intact; always open the clean copy to confirm it looks right before you send it.
