Dates written day / month
Only ISO dates (2024-03-31) become dates: 03/04/2024 could be March or April, so it stays as written rather than risk a swap.

No more broken accents
The file's encoding and separator are recognised, quoted cells keep their commas and line breaks, then each cell is typed: number, date, true / false or text.
Columns are sized to their content and the header row is frozen with filter buttons, so the workbook is ready to read and sort.
Encoding recognisedPrivacy
Exports, customer lists and accounts stay with you: the conversion runs in your browser and the file is never uploaded.
Once the page has loaded, the conversion does not depend on our servers.
