YAML to XML Converter
Convert YAML to well-formed XML for legacy integrations. Preserves nested mappings and sequences as nested elements with text values.
How to use the yaml to xml converter
Paste YAML on the left. XML appears live on the right. Mappings become nested elements; sequences become repeated elements.
Formula & explanation
YAML → JS value → XML via fast-xml-parser. Keys prefixed with "@_" become XML attributes (this is the standard convention).
Examples
name: Alice\nage: 30 becomes <root><name>Alice</name><age>30</age></root>
Frequently asked questions
- How do I produce XML attributes from YAML?
- Prefix the key with @_ — e.g. "@_id: 1" under a parent becomes id="1" on the parent element. This matches the fast-xml-parser convention used across the converters.
- What if my YAML is a sequence at the root?
- XML requires a single root element. We wrap arrays in <root><item>…</item></root> automatically.
