TidySheet

Clean messy spreadsheet data in one click — right inside Excel. Trim stray whitespace, fix casing, remove duplicate rows, split names into columns, extract emails and numbers. No formulas, no Power Query, no uploading your data anywhere: everything runs locally in your workbook.

Install (2 minutes)

  1. Download the manifest above.

  3. Click Clean Data on the Home ribbon.

Free vs Pro

Trimming, casing and blank-row removal are free forever. A one-time Pro license adds duplicate removal, name splitting, email/number extraction, text-to-number conversion and regex find & replace.

Privacy

Your spreadsheet data never leaves Excel. The add-in is a static page with no server, no analytics and no tracking; the only network call is license validation against the payment provider when you activate Pro.
