JSON Formatter Online
About JSON Formatter Online
What does JSON Formatter Online do?
Format, beautify, and validate JSON data so it becomes easier to read, debug, and share.
The JSON Formatter Online takes raw, minified, or poorly formatted JSON and instantly formats it into clean, indented, readable JSON with proper syntax highlighting - right in your browser, with nothing sent to a server. It also validates the JSON and shows any syntax errors with their exact location so you can fix them quickly.
Working with raw JSON from API responses, config files, or data exports is difficult when it is all on one line or inconsistently indented. This formatter beautifies JSON instantly so you can read the structure, find errors, and understand the data. It also works in reverse - minify your JSON to remove whitespace before sending it in an API request or storing it compactly.
How to Use:
- Paste your raw or minified JSON into the input area.
- Click Format / Beautify to apply clean indentation and syntax highlighting.
- If there are errors, the tool highlights them with the line number.
- Optionally click Minify to compress the JSON back to a single line.
- Copy the formatted or minified output.
Best For:
- Formatting and reading API response JSON during development
- Validating JSON config files before deploying
- Debugging JSON syntax errors in data exports
- Minifying JSON before storing or sending in a request
