JSON Formatter
Paste unformatted JSON and get it back neatly indented and easy to scan. If the JSON is broken, you get the exact position of the problem instead of a silent failure.
How to use the JSON Formatter
- Paste your JSON into the input box, or press "Load sample" to try an example.
- Choose an indent style: 2 spaces, 4 spaces or tab.
- Press Format. The formatted JSON appears in the output box.
- Copy the result, or download it as a text file.
About this tool
JSON is the language of APIs and config files, but machines write it in one long line. A formatter restores the structure — nesting, arrays and objects — so humans can read, review and debug it. This formatter parses your input properly rather than guessing with search-and-replace, so invalid JSON is reported with its position instead of being mangled.
