Frequently Asked Questions

How are XML attributes represented in YAML?
By default, XML attributes are mapped to YAML dictionary keys prefixed with "@" (for example, <server id="app-01"> becomes @id: app-01). You can also configure them without prefixes or ignore them completely.
How does the converter handle multiple child elements with the same tag?
When an element contains multiple child tags with the exact same name (such as repeated <item> or <service> tags), the engine automatically coalesces them into a standard YAML bullet list.
Is my XML file uploaded to any cloud server?
No. The entire conversion executes 100% in your browser using local JavaScript. No data is stored, cached, or transmitted over any network.
