Is my XML data sent to a server?

No. The entire conversion runs in your browser using the native DOMParser and js-yaml library. Your data never leaves your device.

Does it support XML attributes?

Yes. Attributes on an element are grouped under an `@attributes` key in the YAML output, following a common convention for XML-to-object mapping.

What happens with repeated sibling elements?

Repeated elements with the same tag name at the same level are converted into a YAML sequence (list), which is the natural YAML equivalent.

Does it handle XML namespaces?

Namespace prefixes are preserved as-is in the key names (e.g., `ns:element`). Namespace declarations (`xmlns:*`) are treated like regular attributes.

Can I convert very large XML files?

The tool works well for typical config files and API payloads. Very large files (several MB) may be slow depending on your device, since all processing is done in the browser.

Summary

This tool converts XML documents to YAML format directly in your browser using the native DOMParser API and the js-yaml library. No data is sent to any server — your XML stays completely private. The converter handles nested elements, attributes, text content, and repeated sibling nodes.

How it works

Paste or type your XML into the input panel.
The tool parses the XML with the browser's built-in DOMParser.
Each element, attribute, and text node is mapped to a YAML structure.
Repeated sibling elements at the same level become YAML sequences.
Attributes are included under an `@attributes` key.
The formatted YAML is displayed instantly in the output panel.

Use cases

Convert API responses from XML to YAML for config files.
Migrate legacy XML configuration to modern YAML-based tools.
Quickly inspect XML structure in a more readable format.
Prepare XML data for Kubernetes or Docker Compose YAML configs.
Transform RSS/Atom feed XML into structured YAML.
Debug complex nested XML documents with a cleaner view.
