  • Choose semicolon delimiter for European formats if required.
  • Hidden sheets may still appear depending on the workbook structure.
  • Your Excel file is processed locally — no upload.

Frequently asked questions

Will formulas be preserved in the CSV?
No. CSV stores the calculated values of cells, not the formulas themselves. This is by design — CSV is a plain-text format that does not support Excel-style formulas.
What happens to multiple worksheets?
Only one worksheet can be converted per CSV file. Select the sheet you need before converting. To export all sheets, convert them individually.
Is my spreadsheet data kept private?
Yes. All conversion runs locally in your browser. Your file is never sent to our servers.
