About YAML
YAML is an indentation-based format used for Kubernetes manifests, Docker Compose, GitHub Actions, OpenAPI specs and countless config files. It is a superset of JSON that favours readability.
About XML
XML is a markup format for structured documents and data, still common in SOAP APIs, RSS feeds, Android resources, Maven builds and enterprise integrations. Elements can carry attributes as well as child elements.
How it works
Keys starting with @ become attributes. A single top-level key becomes the root element; otherwise everything is wrapped in <root>.
Private by design
Developer data is often sensitive: API responses, tokens, customer records, internal configs. This YAML to XML processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.
