How to use the YAML to JSON

YAML vs JSON

JSON is strict, compact, machine-friendly — every web API uses it. YAML is human-friendly: comments, multi-line strings, indentation instead of braces. Kubernetes, Docker Compose, GitHub Actions and Ansible all use YAML for config because it's much easier to read. Every valid JSON is also valid YAML (YAML is a superset).

Limitations

This converter handles standard YAML features: scalars, mappings, sequences, basic types. It does not handle YAML anchors (&ref), aliases (*ref), complex tags, or multi-document streams. For full-spec YAML, use a dedicated YAML library in your code.
