Yes, the converter handles nested objects, arrays, inline collections, comments (stripped in JSON output), and multi-line strings.

Can I convert Kubernetes manifests?

Yes, this is ideal for converting K8s YAML manifests to JSON for API calls, or converting JSON API responses back to YAML for config files.

Are YAML anchors and aliases supported?
