Format, validate or minify JSON in your browser
Paste JSON and choose pretty-print formatting or minification. The utility parses the text, so invalid JSON is reported instead of silently being treated as valid data.
Example and important limitation
For example, format a response from a developer tool for easier review. JSON requires quoted property names and does not permit comments or trailing commas.
