JSON Strengths
- Great for APIs
- Easy to parse in code
- Strict syntax reduces ambiguity
YAML Strengths
- Easier for humans to read in many configs
- Supports comments
- Popular in DevOps and infrastructure tooling
Trade-Offs
YAML is often friendlier for editing, but it is also easier to break with indentation mistakes. JSON is stricter and more predictable for machines.
Use JSON Validator for API payloads and YAML Validator when reviewing config files.
