Are comments preserved?

JSON has no comments, so the generated YAML contains none. You can add them freely after downloading.

How are nested arrays handled?

Arrays become block sequences with dash items, nested according to their depth in the source document.

Can I download the result?

Yes, the Download button saves the output as a .yaml file directly from your browser.

About the JSON to YAML

YAML is the configuration language of Kubernetes manifests, GitHub Actions workflows and countless CI systems, while APIs almost always speak JSON. Converting between the two is a daily task.

Because YAML is a superset of JSON, every valid JSON document has a YAML equivalent. The output uses two-space indentation and quotes strings only when required.
