JSON Formatter
Format and beautify JSON free in your browser. No sign-up — your data never leaves your device.
The Ultimate JSON Formatter
JSON (JavaScript Object Notation) is the standard data-interchange format on the web. However, minified or unformatted JSON is virtually impossible for humans to read. Our JSON Formatter instantly parses, validates, and beautifies your JSON data into a clean, hierarchical view with proper indentation and syntax highlighting.
How to use
- Paste your raw JSON string into the editor.
- Click "Format" to automatically indent and beautify the code.
- Use the "Minify" option if you need to compress the JSON back into a single line for production.
Common use cases
- Debugging API responses from servers.
- Reading complex configuration files.
- Preparing JSON payloads for POST requests.
