JSON Formatter
Format, validate, and beautify JSON data with syntax highlighting.
About JSON Formatter
JSON often becomes hard to read at the exact moment you need to inspect it carefully, such as during API debugging, frontend integration work, or configuration cleanup. This formatter is built for those moments. You can paste raw JSON from an API response, make it readable, validate the syntax, and then minify it again if needed for storage or transport. Because the tool runs in the browser, it is also a convenient option when you want a quick check without sending internal payloads to an external service.
How to Use
- 1Paste the JSON payload or configuration block you want to inspect
- 2Format it to make the structure readable and easier to scan
- 3Validate the syntax if you suspect a broken comma, quote, or bracket
- 4Minify it again if you need a compact version for transport or storage
- 5Copy the result back into your editor, API tool, or documentation
