Common problems and fixes
YAML list items are not mapping to the XML element name I want.
YAML sequences become repeated XML elements with a generated tag name derived from the parent key. If the tag name is not right, rename the parent key in the YAML before converting.
YAML keys with special characters produce invalid XML tags.
XML element names must start with a letter or underscore and cannot contain spaces or most punctuation. Rename those YAML keys to use only letters, digits, hyphens, and underscores before converting.
YAML anchors and aliases are producing unexpected output.
The converter resolves YAML anchors and aliases before converting — aliases are expanded into their full referenced values. Check that the anchor definitions in the source YAML are correct to ensure the expanded values are what you expect.

Frequently asked questions
How do I convert YAML to XML?
Paste your YAML into the input box, run the converter, and copy or download the XML output.
Does this YAML to XML converter add a root element when needed?
Yes. Primitive or list YAML input is wrapped in a root element so the output remains valid XML.
Is this YAML to XML converter free?
Yes. It is free to use in your browser.
Can I convert XML back to YAML?
Yes. Use the XML to YAML converter to go in the other direction.
What happens to YAML null values when converting to XML?
YAML null values are output as empty XML elements since XML has no native null type. The element tag is present in the output but has no text content.
Why would I need YAML to XML instead of YAML to JSON?
Use YAML to XML when the receiving system, service, or tool specifically requires XML input — such as a SOAP API, an enterprise integration platform, or a legacy application. For modern APIs and web services, JSON is usually preferred.
