The problem

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".

Before and after: a messy column of names becomes clean in one click BEFORE A — Customer ␣␣jane DOE␣ JOHN␣␣smith JOHN␣␣smith dup (blank row) a.lee@corp.com Ann Lee one click AFTER First Last Jane Doe John Smith Ann Lee ✓ trimmed · cased · deduped
Stray spaces, wrong casing, duplicates and blank rows — gone. Names split into clean First / Last columns.

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?
