When JSON is the better fit
- - When you need strict validation, stable structure, and machine-friendly processing.
- - When the next step is formatting, diffing, JSONPath, or code generation.
- - API responses, logs, and automation flows are usually easier to debug in JSON.
When YAML is the better fit
- - When people need to edit config files or deployment templates frequently.
- - When you want less quote and brace noise for human-authored configuration.
- - When your team already has strong YAML conventions in tooling or deployment systems.
