{ } JSON Formatter
Beautify, validate, and format messy JSON.
Practical guide
How to use JSON Formatter
Format, validate, beautify and minify JSON directly in your browser. Paste messy JSON, click Format, and get readable indented output you can copy into your app, API client or documentation.
Common uses
- Debug API responses
- Clean configuration files
- Validate JSON before pasting into production tools
- Minify JSON for compact storage
Good practice
Validate the formatted result before committing configuration changes. A formatter can expose syntax errors, but it cannot confirm that field names or values are correct for your application.
Data handling
Formatting is performed for the current request. Remove API keys, tokens, personal records, and production credentials before pasting JSON into any online utility.
