CSV to JSON Converter
Convert CSV to JSON arrays with the first row as keys — and JSON back to CSV. Parses quoted fields and handles commas correctly.
About this tool
This converter transforms CSV data into a JSON array of objects and back again. The first CSV row is used as object keys, and the parser handles quoted values, embedded commas and newlines correctly.
It is the quick bridge between spreadsheet exports and JavaScript: export from Excel, Google Sheets or a database, past it in, and get working JSON for an app or API payload. The reverse direction turns any JSON array into a downloadable-ready CSV table.
FAQ
How does CSV to JSON work?
The first row becomes object keys and every following row becomes one object. Quoted fields containing commas are parsed correctly.
Does it handle headers with spaces?
Keys are trimmed automatically, so " name " becomes "name". Duplicate keys overwrite in order of appearance.
Can I convert JSON back?
Yes — paste a JSON array of objects and press the reverse button to get clean CSV with quoted fields where needed.
