How it works

STEP 1

Add your spreadsheet

Drop an .xlsx file, or just paste the cells you copied from Excel or Google Sheets.

Pick sheet & separator

Choose which sheet to export and whether to use a comma, semicolon or tab between columns.

STEP 3

Preview & download

Check the table preview, then copy the CSV or download the file — nothing leaves your device.
