Is my XML data sent to a server?

No. The entire conversion runs in your browser using the native DOMParser API. Your data never leaves your device.

Does it support XML attributes?

Yes. Attributes on an element are included as regular key-value pairs alongside the element's children in the TOML output.

What happens with repeated sibling elements?

Repeated elements with the same tag name at the same level are converted into a TOML array of tables ([[section]]), which is the natural TOML equivalent.

Can TOML represent all XML structures?

TOML is designed for flat configuration data, so deeply mixed content (text interleaved with elements) or XML namespaces may be simplified or flattened during conversion.

What TOML spec version does this target?

The output targets TOML v1.0. All generated keys, strings, integers, and tables follow the TOML v1.0 specification.
