How to Convert YAML to XML
Create a structured XML document from YAML in three focused steps.
Map the hierarchy
Choose the root behavior, then convert mappings, sequences, attributes, and text into XML nodes.
Export the XML
Review the formatted document, copy it, or download a clean UTF-8 .xml file.
Structured Conversion for Real YAML Data
YAML uses indentation, mappings, and sequences to describe structured information. XML uses elements, attributes, and text nodes. This converter bridges those models with deliberate rules instead of simply replacing punctuation.
Keys beginning with @ become XML attributes, #text becomes element text, and YAML arrays generate repeated sibling elements. Element names are validated and all values are XML-escaped.
- Handles nested mappings and repeated sequence items
- Supports explicit attributes and mixed element text
- Runs locally without registration or server uploads

Why Use This YAML to XML Converter?
A polished workflow for developers, integrations, migrations, and configuration data.
Private processing
Your YAML remains in the browser and is never submitted to the website server.
XML-safe output
Reserved characters are escaped and element names are checked before XML is created.
Hierarchy aware
Nested YAML becomes readable XML with consistent two-space indentation.
Frequently Asked Questions
Practical details about converting YAML structures into XML.
Is this YAML to XML converter free?
Yes. You can paste, upload, convert, copy, and download without creating an account or paying a fee.
How do I create XML attributes from YAML?
Prefix a YAML key with @. For example, "@id": 42 becomes the XML attribute id="42".
How are YAML arrays converted?
Each array item becomes a repeated XML element using the array key as its element name.
What does the #text key do?
The special #text key adds text inside an element that also contains attributes or child elements.
Is my YAML sent to the server?
No. Parsing, XML generation, preview, copying, and download creation happen locally in your browser.
What happens if an XML element name is invalid?
The converter stops and identifies the invalid name so you can correct the YAML key instead of downloading malformed XML.
