CleanMySheet guide

Download Google Sheets as CSV and clean it locally

Google Sheets has no private, recipe-based cleaner. Download CSV, drop it on CleanMySheet, apply presets, and upload the result back (File → Import) if you still want it in Sheets.

Open the cleaner

Steps

  1. File → Download → Comma-separated values
  2. Drop on CleanMySheet
  3. Apply presets
  4. Import the CSV back

Why not a Sheets add-on yet

Add-ons require OAuth and cloud access. A file workflow keeps Strict mode honest: nothing leaves the browser.
