Guides / YAML vs JSON
YAML vs JSON — When to Use Each
JSON is the default for APIs and many app configs. YAML is popular for Kubernetes, CI pipelines, and human-edited infrastructure files because it is less noisy for nested structures.
Quick comparison
- JSON — strict syntax, ubiquitous in HTTP APIs, easy to parse everywhere
- YAML — indentation-based, supports comments, nicer for long configs
- Interchange — most YAML documents map cleanly to JSON data structures
When to convert
Convert YAML to JSON when an API or library expects JSON. Convert JSON to YAML when you want a readable config checked into git with comments added afterward.
