YAML JSON

Supports common YAML: maps, lists, scalars, quotes, --- docs. Advanced features (anchors, merge keys, complex multiline) are not fully supported — validate critical manifests with your cluster tooling.

Common Uses

Turning a Deployment/ConfigMap into JSON for an API call
Inspecting Helm or Kustomize output as JSON
Moving config between tools that prefer different formats

Advanced YAML (anchors, merge keys, complex multiline blocks) may need kubectl / a full YAML library for perfect fidelity.
