CSV to JSON Converter
Paste CSV, get JSON — with proper handling of quoted fields, embedded commas and newlines. Nothing is uploaded.
Frequently asked questions
How are commas inside values handled?
Per the CSV standard (RFC 4180): fields containing the delimiter, quotes or newlines are wrapped in double quotes, and quotes inside are doubled. "Smith, Bob" parses as one field. This parser handles all of that, including multi-line quoted fields.
What does the headers option change?
With headers on, each row becomes an object keyed by the first row ({"name": "Alice"}). Off, each row becomes a plain array — useful when the file has no header row.
Is my data uploaded?
No — parsing happens entirely in your browser, so customer lists and exports stay on your machine. The reverse direction is our JSON to CSV converter.
