  • • Use "Minify" to reduce JSON size for production or network transmission
  • • Use "Beautify" to make JSON human-readable for debugging
  • • The depth metric shows the maximum nesting level in your JSON structure
  • • Click "Use Output" to pipe formatted JSON back to the input for further processing
