Messy data wastes your day
Pasted lists full of stray spaces. Names crammed into one column. Duplicates hiding in 2,000 rows. Emails buried in free text. Numbers that Excel insists are text. Excel can fix all of it — if you remember the right formula, wizard, or Power Query incantation. Most people don't.
TidySheet puts the fix one click away. Select your cells, open the TidySheet pane on the Home ribbon, click a button. Done. No formulas, no helper columns, no Googling "TRIM not working".

The free tools stay free forever — Pro is for the heavy lifting. One payment, no subscription.

FAQ
Is my spreadsheet data safe?
Yes. TidySheet runs locally in your workbook via Microsoft's Office.js API. No uploads, no cloud processing, no analytics, no tracking. See the privacy policy — it's short.
What if a cleanup does something I didn't want?
Excel's undo (Ctrl+Z) works on every TidySheet operation, so you're never more than one keystroke from where you started.
Does it work on Mac and Excel on the web?
Yes — Windows, Mac, and Excel on the web, with the same buttons and the same results.
What if it doesn't save me time?
30-day money-back guarantee, no questions asked. Reply to your Gumroad receipt or email [email protected].
