Format, minify, and validate JSON, with clear error locations.

How it works

No. Parsing, formatting, and validation all happen locally in your browser using JavaScript’s built-in JSON support.

Frequently asked questions

Does this tool upload my JSON anywhere?
No. Parsing, formatting, and validation all happen locally in your browser using JavaScript’s built-in JSON support.
How is the error location determined for invalid JSON?
The browser’s JSON parser reports the character position where it got stuck; this tool converts that into a line and column so it’s easier to find.
