Frequently Asked Questions

Can I convert a Kubernetes YAML manifest to JSON?

Yes. Kubernetes accepts both formats internally, so converting a Deployment or Service YAML manifest to JSON produces something kubectl can apply directly with kubectl apply -f file.json.

Does it handle YAML anchors and aliases?

Standard YAML anchors (&) and aliases (*) are resolved during parsing, so the resulting JSON contains the fully expanded values rather than references.

What if my YAML has a syntax error?

The converter reports the exact parse error, including line number where possible — usually caused by mixed tabs/spaces or inconsistent indentation.

Are multi-document YAML files (separated by ---) supported?

This converter parses a single YAML document. For multi-document files, convert each document separated by --- individually.

Is my YAML uploaded anywhere?

No. Parsing happens entirely client-side in your browser — nothing is sent to a server, which is safe for private config files and secrets-adjacent manifests.
