Standard Format

JSON is a text-based format for representing structured data. Standardizing formatting with proper indentation allows engineering teams to review pull requests and API contracts efficiently.

Quick Tips

  • Ensure all keys in your JSON object are enclosed in double quotes (e.g. "name").
  • Make sure trailing commas are removed from arrays and object definitions.
  • For deep nested trees, 4-space indentation is highly readable, whereas 2-space is more compact.
