Tips & Best Practices

  • JSON must be valid - all strings must be in double quotes, not single quotes.
  • Trailing commas are not allowed in JSON.
  • Use Format for readability and debugging, Minify for production/API use.
  • The formatter automatically detects and highlights syntax errors.
  • Perfect for API development, configuration files, and data processing.
