FAQs
Can I convert all sheets at once?
Not yet — each sheet becomes its own CSV file, so pick the sheet you need and convert it. You can repeat the process for other sheets.
Will my formatting and formulas survive?
Formula results come through, but formatting, charts and macros do not — a CSV stores plain text values only.
Is my file uploaded anywhere?
No. This tool runs entirely in your browser — your file is never sent to any server.
