  • Format JSON with customizable indentation
  • Minify JSON to reduce file size
  • Validate JSON syntax
  • Optionally validate JSON against a provided JSON Schema
  • Sort object keys alphabetically
  • Copy formatted JSON to clipboard
  • Access your recent formatting history
Common Uses:
  • Making API responses readable
  • Debugging configuration files
  • Preparing JSON for documentation
  • Validating JSON before using it in an application
  • Ensuring JSON data conforms to a specific structure using JSON Schema
All formatting and validation is performed in your browser. Your data is never sent to any server.
