Frequently asked questions
Is my data uploaded?
No — parsing runs in your browser with Papa Parse. Your data never leaves the page.
Are commas inside quoted fields handled?
Yes. Parsing is RFC 4180-aware: quoted fields, escaped quotes, embedded commas and newlines all parse correctly, and the delimiter (comma, semicolon, tab) is auto-detected.
