What Is YAML to XML?
YAML uses indentation for structure; XML uses tags and attributes. Converting YAML to XML turns keys into elements and nested structures into child elements. The YAML 1.2 specification and W3C XML specification define the formats.
This tool parses your YAML and outputs equivalent XML. Conversion runs entirely in your browser. Nothing is sent to a server, so it's safe to use with production configs, Kubernetes manifests, or sensitive data. For JSON instead, use YAML to JSON.

How to Use This Tool
Paste or Upload YAML
Copy your YAML and paste it into the left editor. You can also click Upload to load a .yaml or .yml file. The Sample button loads example data. Invalid YAML will show an error—use the YAML Validator to diagnose.
View XML Output
The right panel shows the converted XML. YAML keys become XML elements; nested objects become child elements. Arrays become repeated elements. Invalid YAML will show an error in the output.
Copy or Download
Use Copy to put the result on your clipboard, or Download to save it as a .xml file. For the reverse conversion, use XML to YAML. For YAML formatting, use YAML Formatter.
When YAML to XML Helps
XML is common in SOAP APIs, RSS/Atom feeds, and enterprise systems. If your config or data is in YAML (e.g. Kubernetes manifests, Docker Compose) but the target system expects XML, this tool does the conversion. Config files like application.yml or GitHub Actions workflows can be converted for systems that only accept XML input.
Some legacy tools and integrations require XML. Converting YAML here gives you valid XML you can feed into XSLT, XPath, or XML parsers. For JSON instead, use YAML to JSON. For querying XML, use the XML XPath tool.
Frequently Asked Questions
When to use XML vs YAML?
XML is common in SOAP, feeds, and enterprise systems. YAML is better for config files, Kubernetes, and DevOps. Use this tool when you need to bridge the two—e.g. feeding YAML config into an XML-based pipeline.
Does it preserve comments?
No. XML supports comments with <!-- -->, but YAML comments are not carried over. The conversion focuses on structure and data.
Is my data private?
Yes. Conversion runs entirely in your browser. No data is sent to any server.
How are arrays handled?
YAML arrays become repeated XML elements with the same tag name. For example, a list of items becomes multiple <item> elements.
Can I add attributes to elements?
The default conversion produces elements with text content. For custom attribute mapping, you may need to post-process the XML or use a different approach. The output is valid, well-formed XML.
