JSON formatter
Format, validate and minify JSON.
Input
Output
Output appears here as you type.
What this does
Parses with the browser’s own JSON parser, so what validates here is exactly what validates in your code. Errors report the line and column.
Limits
- Strict JSON only. No comments, no trailing commas, no single quotes.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
