What happens if my spreadsheet has multiple sheets?

CSV is a single-sheet format, so only the first sheet in your workbook is converted. If you need a specific sheet, make sure it's first, or split it into its own file before converting.

Will formulas be preserved?

No. The CSV will contain each cell's calculated value, not the underlying formula — CSV has no concept of formulas.

Are my files kept private?

Your files are processed on our servers solely to perform the conversion. They are deleted automatically once the download is complete and are never shared or stored long-term.

What is the file size limit?

Files up to 10 MB are supported.
