How to convert YML to XML
- Add your .YML file - drop it in the box above or click to browse.
- Convert it to .XML in a few seconds.
- Download your new .XML file.
What to expect
- YAML comments (lines beginning with
#) are silently dropped - they have no equivalent in the XML data model. - YAML keys always become XML child elements, never attributes; if the target schema requires
xmlnsnamespaces or attribute syntax, manual post-processing is needed. - Multi-document YAML files separated by
---must be split into single documents before converting - most tools only handle one YAML document at a time.
Frequently asked questions
Is YML-to-XML conversion lossless?
Data values (strings, numbers, booleans, lists, nested objects) all carry over. Comments, type coercion hints, and structural metadata are lost, and the element-vs-attribute mapping may not match what a specific schema expects.
Can I convert XML back to YML?
Yes - run
xq -y on the XML file or use Python's xmltodict.parse followed by yaml.dump. Note that XML attributes become @-prefixed keys in the YAML output.Why does the converted XML not match what my system expects?
Generic converters apply default element-naming rules that may differ from your target schema. You will need a schema-aware tool or a short custom script that maps YAML keys to the exact element names your system requires.
Does this work for Kubernetes or Ansible YAML files?
The conversion itself works, but those files are often multi-document (separated by
---). Split them into individual files first using yq before converting to XML.
