Frequently Asked Questions

How does this tool handle XML attributes in YAML?
Keys starting with "@" (such as @id: app-01) are automatically converted into XML attributes on their parent element.
Can I customize the root tag for the generated XML?
Yes! You can specify any custom root element name in the Root Tag option. If your YAML has a single top-level key, it automatically becomes the root tag.
Is my YAML data sent to any server?
No. All parsing and XML serialization run entirely client-side in your web browser. No data is stored, logged, or transmitted over any network.
