What is a YAML formatter?

A YAML formatter restructures YAML with consistent indentation and spacing, making Kubernetes manifests, Docker Compose files, and CI configs easier to read and review.

Can I convert YAML to JSON?

Yes. Click To JSON to convert your YAML document into formatted JSON — useful for APIs and debugging.

Does this validate Kubernetes YAML?

It validates YAML syntax (structure and indentation). For K8s-specific schema rules, apply manifests with kubectl --dry-run=client after formatting.

Is my YAML sent to a server?

No. All formatting and validation runs entirely in your browser.
