About CSV to JSON

The parser follows RFC 4180: quoted fields may contain delimiters, quotes and line breaks, and blank lines are skipped. With a header row each line becomes an object whose keys are the column names. Convert the other way with the JSON to CSV converter.

Frequently asked questions
