Convert YAML to XML Online
Enterprise integrations, SOAP services and many legacy systems still speak XML. If you write modern configuration in YAML but need to push it into an XML-only pipeline, this converter renders well-formed XML with proper element nesting and root wrapping. Indentation is preserved for readability. Output is UTF-8 XML 1.0.

When you'd convert YAML to XML
Real-world scenarios where this conversion is the right move.
Feed SOAP and legacy services
Many enterprise systems still require XML payloads. Convert your YAML source of truth before sending.
Generate Maven, Spring or Android resources
Java tooling often expects XML. Maintain your config in YAML, convert when you need pom.xml-style output.
Document interchange
When you need to share data with a team that uses XML-based tooling, YAML is the better source format to maintain.
YAML vs XML — what changes
Quick reference for the structural differences between both formats.
| Aspect | YAML | XML |
|---|---|---|
| Arrays | YAML sequences with - | Repeated elements with the same tag name. |
| Verbosity | Minimal — keys appear once. | Tags repeat (open + close) and are longer to read. |
| Attributes vs elements | Everything is a key. | XML distinguishes attributes (@key) from child elements. |
| Schemas | JSON Schema, optional. | XSD and DTD validation natively supported. |
Frequently asked questions
Can I get XML attributes instead of child elements?
Prefix keys with @ in your YAML and they render as XML attributes — for example @id: 42 becomes id="42" on the parent element.
Does the output include an XML declaration?
Yes. The output starts with <?xml version="1.0" encoding="UTF-8"?> so consumers parse it correctly.
What about namespaces?
Add xmlns:* keys in your YAML and they pass through to the root element. The converter does not invent namespaces on its own.
Is multi-document YAML supported?
Each document wraps in its own root. Concatenate manually if you need a single XML document.
