JSON Formatter
Paste messy or minified JSON below and format it, or shrink it back down. Runs entirely in your browser, nothing is sent anywhere.
Formatted output will appear here.
How to use this
Paste any JSON into the box on the left, then choose whether you want it formatted with clean indentation for readability, or minified down to a single line for production use. If something's wrong with your JSON, like a missing comma or an unclosed bracket, this tool will tell you instead of just failing silently.
