JSON to CSV Converter
Turn a JSON array of objects into clean, spreadsheet-ready CSV.
CSV will appear here.
Paste a JSON array of objects to convert it into CSV with a header row built from the object keys. Commas, quotes and newlines inside values are escaped per RFC 4180, and nested values are JSON-encoded so nothing breaks in Excel or Google Sheets. Everything runs in your browser.

Frequently asked questions
What JSON shape does it expect?
An array of objects, like [{"name":"Ada"},{"name":"Linus"}]. The CSV header is the union of all object keys.
How are commas and quotes handled?
Any value containing a comma, double quote or line break is wrapped in quotes, with embedded quotes doubled — the standard CSV escaping rules (RFC 4180).
Is my data uploaded?
No. The conversion runs entirely in your browser; nothing is sent to a server.
