❓ Frequently Asked Questions
Is my Excel data private?
Absolutely. All conversion happens in your browser – your file never leaves your device.
What Excel formats are supported?
Both .xlsx (Excel 2007+) and .xls (Excel 97-2003) are supported.
Will my formatting be preserved?
CSV is a plain‑text format, so only the raw data is kept. Formulas are evaluated to their current values.
What about multiple sheets?
Only the first sheet is converted. If you need multiple sheets, check our desktop tool.
