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.
