XML to YAML Converter
Guide
XML to YAML Converter
Paste any XML document and instantly get clean, readable YAML. This converter runs entirely in your browser and faithfully preserves structure, attributes, and repeated elements that automated rewriters often drop or collapse. It is ideal for migrating configuration files, API payloads, or data exports from XML into the more concise YAML format.
How to Use
- Paste your XML into the input box, or load the built-in example.
- Choose how attributes should be handled: keep them with an
@or_prefix, or merge them flat into the object. - Optionally strip namespace prefixes and toggle whitespace trimming or array wrapping for repeated siblings.
- Pick a 2- or 4-space indent, then copy or download the generated
.yamloutput.
Features
- Attribute preservation – Keep XML attributes as prefixed keys or merge them flat, so nothing is silently discarded.
- Array detection – Repeated sibling elements are grouped into proper YAML lists instead of being overwritten.
- Namespace stripping – Optionally remove namespace prefixes for cleaner output.
- Input validation – Malformed XML is caught and reported before any conversion happens.
- Client-side only – Your data never leaves the browser, and you can download the result as a YAML file.
FAQ
-
What is the difference between XML attributes and child elements?
Attributes are name-value pairs written inside an element's opening tag, while child elements are nested tags with their own content. YAML has no native attribute concept, so a converter must map attributes to ordinary keys (commonly with an @ prefix) to keep them distinct from element data.
-
Why does YAML rely on indentation instead of closing tags?
YAML expresses hierarchy through indentation levels rather than matching open and close tags like XML. This makes documents shorter and easier to read, but it also means whitespace is significant and consistent indenting is required for valid output.
-
How are repeated XML sibling elements represented in YAML?
When several sibling elements share the same tag name, they represent a collection. A correct conversion groups them into a YAML sequence (a list of items) under that key, preserving order, rather than letting later siblings overwrite earlier ones.
