Frequently asked questions

Does it handle all YAML features?

It handles the most common subset: nested objects, scalars, and simple key-value pairs. Anchors, aliases, multi-document streams, and complex sequences are not supported.

Can I convert Kubernetes manifests?

Yes, typical K8s manifests with flat and nested fields convert cleanly. Array items (- syntax) have limited support.
