Frequently Asked Questions (FAQ)

Q: Will converting large files upload my confidential data?

Never. All data parsing runs 100% locally in browser memory following RFC 4180. No network requests are sent.

Q: Can it handle commas or newlines inside quoted CSV cells?

Yes. The parsing algorithm strictly complies with RFC 4180 quote escaping rules for multi-line and embedded commas.
