About This Tool
JSON Formatter takes minified or poorly indented JSON and outputs a cleanly indented, human-readable version with proper spacing and line breaks. Working with minified JSON in logs or API responses is painful — formatting it instantly makes debugging far faster.
Well-formatted JSON is also easier to diff, review in pull requests, and share with teammates. Keeping stored JSON readable prevents a class of subtle errors caused by misreading compact output.
Tip: Paste the raw API response directly — the formatter handles escaped characters, nested objects, and arrays. If it fails, there is likely a syntax error in the source, which the JSON Validator can pinpoint.
