JSON Formatter
Format, validate, and minify JSON instantly — with exact error line & column, key/depth stats, and sorted keys. Nothing uploaded.
How to use the JSON Formatter
Paste JSON — it validates as you type. Tap 2 spaces, 4 spaces, Tab, or Minify to reshape it; the chosen style stays highlighted. Invalid JSON gets the exact line and column of the problem. Everything runs locally — safe for sensitive data.
Options
- Indent — 2 spaces, 4 spaces, tabs, or minified to one line.
- Sort keys A→Z — alphabetize every object's keys, at every depth.
- Stats — total keys and nesting depth, plus the byte size.
