How to use the JSON Formatter & Validator

Paste your JSON.
Click Format to beautify it, or Minify to compress it.
Copy the result — or read the error message if it isn't valid.

Tips

A trailing comma after the last item in an object or array is a common cause of invalid JSON.
Keys and string values both need double quotes — single quotes aren't valid JSON.
Minified JSON is smaller to transmit but harder to read; keep a formatted copy for editing.
