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.
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.
How it works
XML attributes become keys prefixed with @, repeated elements become arrays, and text next to child elements is stored under #text. Numbers and booleans are detected automatically.
Private by design
Developer data is often sensitive: API responses, tokens, customer records, internal configs. This XML to YAML processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.

Does the XML to YAML conversion lose data?
