JSON Formatter
Paste raw JSON below to validate and beautify it, or minify it into a single line.
How to use this tool
Paste any JSON string into the input box and choose Beautify to format it with proper indentation, or Minify to compress it into a single line — the output updates instantly as you type or switch styles. If the JSON is invalid, an error message explains what and where the problem is. Everything runs locally in your browser — nothing is uploaded.
