JSON CSV

Convert JSON to a spreadsheet-ready CSV, or CSV back to clean JSON — instantly, with no upload and no signup.

🔒 100% LOCAL — YOUR DATA NEVER LEAVES YOUR DEVICE

JSON to CSV, the private way

Paste an array of JSON objects and get a CSV you can open in Excel or Google Sheets — each object becomes a row, each key a column, and nested values are preserved as JSON text. Everything runs in your browser: API responses, exports, and customer data are never uploaded to anyone's server, including ours.

CSV to JSON for developers

Going the other way, the first row becomes your keys and every following row an object — with numbers and booleans automatically typed, ready to paste into code or an API call. Semicolon and tab-delimited files work too.
