Frequently asked questions

Which sheet is exported?+

The first worksheet in the workbook. If you need a different sheet, move it to the front in Excel before converting.

Are formulas exported?+

Their calculated values are exported, which is what a CSV can store. Formatting and formulas themselves are not part of the CSV format.

Are my files uploaded?+

No. The conversion runs entirely in your browser on your device — your spreadsheet is never uploaded.
