About XML to YAML Converter
The XML to YAML converter parses XML using fast-xml-parser and serialises the resulting structure to YAML via js-yaml — routing through a clean intermediate JavaScript object so all nesting, repeated elements, and attributes are faithfully represented. Both editors are live. The YAML output panel supports interactive tree and graph visualization of the parsed data.
Features
- ✓Bidirectional — edit either panel and the other updates in real time
- ✓Two-stage pipeline: fast-xml-parser parse → js-yaml serialise
- ✓Repeated XML elements → YAML sequences
- ✓XML attributes preserved as YAML mapping entries
- ✓YAML output has interactive tree view and graph visualization
- ✓Swap direction to YAML→XML with a single click
- ✓Download converted YAML as a .yaml file
- ✓Copy output to clipboard in one click
- ✓Web Worker processing — never blocks the UI
- ✓100% client-side — data never leaves your browser

Frequently Asked Questions
QAre XML attributes included in the YAML output?
Yes — fast-xml-parser extracts XML attributes as object properties (using the `@_` prefix by default), which are then serialised as YAML mapping keys.
QIs my data sent to a server?
No. All conversion runs in a Web Worker inside your browser.
