JSON Pretty Print

Paste your JSON in and instantly get it back clean, indented, and easy to read — with full syntax highlighting so keys, values, strings, and numbers are all color-coded at a glance. Need to go the other direction? Minify mode squashes it down to a single line for use in code or config files. Not sure if your JSON is even valid? Validate mode gives you a straight yes or no, with the exact error message if something is off.

No ads. No fees. No signup. Just a tool that works.
