JSON vs YAML
 
 
JSON (JavaScript Object Notation) uses braces and brackets with strict syntax. YAML (YAML Ain't Markup Language) uses indentation-based syntax that is more human-readable. Both are widely used for configuration files, APIs, and data exchange. YAML is popular for Kubernetes, Docker Compose, and CI/CD pipelines.
 
Conversion Notes
 
 
  • JSON is stricter: all keys must be quoted, no comments allowed.
  • YAML supports comments (#), multi-line strings, and anchors — these features cannot be represented in JSON.
  • This tool handles common YAML structures. Very complex YAML (anchors, tags) may need a dedicated parser.
