JSON Formatter and Validator
Validate, pretty-print or minify JSON and see where errors are.
How to use it
Paste JSON and choose Format, Minify or Validate only. Errors are reported using your browser’s JSON parser, so wording can differ between browsers. Your text is processed in your browser and is not uploaded by this tool. Very large integers can lose precision because JavaScript reads them as floating-point numbers.
