A CSV parser that survives real-world files

Naive converters split on every comma and choke the moment a cell contains "Chattogram, GEC". This one implements the actual CSV standard: quoted fields, doubled-quote escapes, line breaks inside cells and Windows line endings all parse correctly. The delimiter is auto-detected (comma, semicolon or tab — semicolons are common in European Excel exports), the first row becomes your JSON keys, and with type detection on, "24" becomes the number 24 and "true" a real boolean — the JSON your code actually wants.

FAQ

Can I paste straight from Excel or Google Sheets?

Yes — spreadsheet copies arrive tab-separated, which auto-detect recognizes instantly. Exported .csv files paste fine too.

How are commas inside values handled?

Standard CSV wraps such values in quotes, and this parser follows the spec — quotes, escaped quotes ("") and even line breaks inside cells parse correctly.

What if I turn off "first row is header"?

You get an array of arrays instead of objects — useful when the data has no column names.
