💡 A proper RFC 4180 parser — handles quoted fields, commas and line breaks inside quotes, and escaped quotes. With "first row is a header" on, you get an array of objects; off, an array of arrays. Everything runs in your browser.

CSV tips

📑

The RFC 4180 parser correctly handles commas and newlines inside quoted fields — where naive split-by-comma breaks.

Escaped double-quotes ("") inside a field are decoded properly.

🔍

If a column looks off, check the delimiter setting — auto-detect handles most files.
