Paste your JSON, format or minify it, and instantly see any syntax errors.
Paste your JSON into the input box and click "Format / Beautify" for readable, indented output, or "Minify" to compress it to a single line. If the JSON is invalid, an error message explains what's wrong.
This is useful for debugging API responses, cleaning up config files, or making dense JSON readable before sharing it with a teammate.
It adds consistent indentation and line breaks to make nested JSON structures easy to read, without changing the actual data.
Formatting adds whitespace for readability. Minifying strips all unnecessary whitespace to produce the smallest possible file size, useful for production use.
If your JSON has a syntax error, this tool shows the specific error message and, where possible, the approximate location so you can find and fix the issue quickly.
No — all parsing and formatting happens locally in your browser using JavaScript's built-in JSON parser. Nothing is sent to a server.
