Convert YAML to XML Online Free
Transform YAML data into well-formed XML documents. YAML mappings become XML elements, sequences become repeated tags, and the output is properly indented. No server upload required.
To convert YAML to XML, drop your .yaml file onto the converter. The YAML is parsed via js-yaml, converted to an intermediate JSON structure, then serialized as well-formed XML using fast-xml-parser. Runs in your browser.

Frequently Asked Questions
YAML sequences (arrays) become repeated XML elements. Each item in the sequence gets its own element with the parent key as the tag name.
YAML comments are removed during parsing. While XML supports comments, they are not added to the output since the source comments are stripped by the parser.
Anchors and aliases are resolved during parsing. The XML output contains the fully expanded data with no reference to the original anchors.
The converter processes the first document in a multi-document YAML file. Split your file at --- separators if you need to convert each document separately.
YAML date values are converted to their ISO 8601 string representation in the XML text content. For example, 2026-02-19 becomes the text content '2026-02-19'.
Yes. The output passes XML well-formedness checks with proper tag nesting, character escaping, and UTF-8 encoding.
YAML null values (null, ~, or empty values) become empty XML elements, like <key/>.
You can convert the XML back to YAML via XML-to-JSON then JSON-to-YAML. Data values are preserved, but YAML-specific features like comments and anchors are lost.
Yes. All processing happens in your browser. No YAML data is sent to any server.
