JSON formatter
Pretty-print, minify and validate JSON with clear error positions.
Your data never leaves your browser and is never stored.
How to use it
- Paste your JSON.
- Hit “Format” or “Minify”.
- If it’s invalid, you’ll see the line and column.
How it works
A quick way to read API responses and fix config files. Parsing happens in your browser and nothing is uploaded.
