Common questions
Is it free?+
Yes — convert XLSX to CSV free. Paid plans add larger files, batch and priority.
Is my data private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
Are leading zeros and IDs kept?+
Yes — cells are read as text, so codes like 007 and long IDs are preserved exactly, never converted to numbers.
