JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write.

Format with custom indentation, sort object keys alphabetically, validate syntax, and minify for production.

Real-time syntax validation helps you identify and fix JSON errors quickly with detailed error messages.

Copy formatted JSON to clipboard or download as .json file for use in your applications.
