About JSON Formatting

JSON formatting transforms compact, single-line JSON into a human-readable format with proper indentation and line breaks. This makes it easier to read, debug, and understand complex data structures.

  • Adds proper indentation for nested structures
  • Places each key-value pair on its own line
  • Optionally sorts object keys alphabetically
  • Validates JSON syntax while formatting
  • All processing happens locally in your browser
