How it works

Paste your JSON into the input field and click "Format" to pretty-print it with readable indentation and spacing. You can also minify formatted JSON back into a compact single line. Invalid JSON will show a helpful error message so you can spot the issue.

Common use cases

• Pretty-printing minified API responses for debugging
• Formatting compact JSON configuration files
• Minifying JSON for production payloads
• Validating JSON syntax with instant error feedback
