XML to YAML Converter

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.

Comment utiliser

1. Paste your XML into the input box, or load the built-in example.
2. Choose how attributes should be handled: keep them with an @ ou _ prefix, or merge them flat into the object.
3. Optionally strip namespace prefixes and toggle whitespace trimming or array wrapping for repeated siblings.
4. Pick a 2- or 4-space indent, then copy or download the generated .yaml sortie.

Caractéristiques

• 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.
• Côté client uniquement – Your data never leaves the browser, and you can download the result as a YAML file.
