FAQ

Excel to CSV questions

See how privacy works

Is Excel to CSV free to use?

Yes. This tool is free to use in your browser and does not require an account.

Are my files private?

Excel to CSV uses SheetJS in the browser. Selected files are processed locally when the required browser features are available, while application, library, model, security, and limited analytics requests may load separately.

What limits should I know about?

1 file · 50 MB max. Very large, encrypted, damaged, or unusual files may not be supported by every browser.

Which worksheet is exported from the Excel file?

Enter a worksheet name to select it. If the field is blank, the tool exports the first worksheet.

Does CSV keep Excel formulas and formatting?

No. CSV stores plain table values only, so workbook formulas, styles, charts, and multiple sheets are not preserved.
