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 cleanerSteps
- File → Download → Comma-separated values
- Drop on CleanMySheet
- Apply presets
- Import the CSV back
