Frequently asked questions
Is my file uploaded anywhere?
No — this tool runs entirely in your browser using JavaScript/WebAssembly. Your file is never sent to a server.
Is there a file size limit?
Free accounts can process files up to the limit shown on this page; signing up for Pro raises that limit substantially.
Are formulas and formatting preserved?
No — only cell values carry over. CSV is a plain-text format with no concept of formulas, cell formatting, multiple sheets, or charts, so converting in either direction keeps values only.
