Convert XML to YAML

Convert XML documents to YAML for more readable configuration files. YAML's indentation-based syntax is cleaner than XML's tags for human-authored data.

1

XML uses tags and attributes; YAML uses indentation and key: value pairs. Converting XML to YAML produces a more readable format for configuration. Attributes become keys (often prefixed with @), text content becomes a #text key, and nested elements become nested objects.

JSON XML Converter →
First convert XML to JSON as an intermediate step. XML attributes map to JSON keys, child elements map to nested objects, and repeated elements map to arrays. This intermediate JSON is then converted to YAML.
3

YAML Converter →
Convert the intermediate JSON to YAML. YAML's syntax is more compact than JSON (no quotes for most strings, no braces/brackets) and supports comments, multi-line strings, and anchors. The result is a human-readable configuration file.

Use the JSON-to-YAML workflow to convert the intermediate JSON to YAML in one step, with validation and formatting.

Caveats: XML to YAML is lossy for mixed content (elements with both text and child elements, common in HTML). XML namespaces, CDATA sections, and processing instructions do not map cleanly to YAML. Use this conversion for data-oriented XML, not document-oriented XML (HTML, DocBook).

Frequently asked questions

Is the XML to YAML conversion lossless?: For data XML (no mixed content, no namespaces), it can be lossless. For document XML (mixed content, attributes, namespaces), information is lost or awkwardly mapped. Use XML for documents, YAML for data configuration.
Why not convert XML directly to YAML?: Going through JSON as an intermediate is more reliable — XML-to-JSON and JSON-to-YAML are well-tested conversions. Direct XML-to-YAML converters are less common and may handle edge cases differently. The two-step approach is more robust.
