Questions

What does JSON to YAML do?

JSON to YAML converts in one direction only. Use YAML to JSON for the reverse.

What YAML features are not supported?

Anchors (&), aliases (*), tags, and merge keys (<<) are not supported. Plain maps, lists, strings, numbers, booleans, and null work.

Can I convert Kubernetes YAML?

Simple manifests without anchors usually work. Complex multi-document files or anchor-heavy configs may need a full YAML parser.

Why convert JSON to YAML?

YAML is easier to read and edit by hand: common for Docker Compose, CI configs, and Kubernetes manifests before JSON APIs need the data.

Is my data sent to a server?

No. Conversion runs entirely in this tab.

Is there a daily limit?

No. This tool has no daily cap.
