Why it's private

Frequently asked questions
Is only the first sheet of my workbook converted?
Yes, in the current version, only the first sheet of your Excel workbook is exported to CSV. If you need a different sheet, move it to the first position before exporting, or split your sheets into separate files.
Can I also convert to JSON, or CSV back to Excel?
Yes, the Spreadsheets tool supports conversions between XLSX, CSV, and JSON, in both directions.
Do I need to create an account to use FiloConvert?
No. There's no account, no sign-up, and no email required. Open the page, convert, download.
Is there a file size limit?
There's no server-imposed limit, since there's no server involved: the conversion happens on your device. The only limit is the memory available on your computer or phone.
