JSON

Google JSON Style Guide

Official Google JSON formatting standards for consistent API responses and configuration.

Quick Reference

Golden Rules

1. Use camelCase — for property names
2. Consistent structure — predictable response format
3. Include metadata — version, timestamps when relevant
4. Use arrays for collections — even single items
5. Null vs omission — be consistent
6. ISO 8601 for dates — standard format
7. Pretty print in development — minify in production

  "userId": 123,

    ]
  },
  "meta": {
    "total": 2,
