XML to TOML

XML is a widespread markup format for data exchange, configuration and documents - with tags, nested elements and attributes. TOML is the highly readable configuration format of the Rust and Python toolchains, with sections in square brackets and plain key-equals-value lines. This tool reads your XML file and writes the same tree as well-formed TOML.

The conversion runs entirely locally in your browser: fast-xml-parser reads the XML, smol-toml writes the TOML, both pure JavaScript. Because an XML document has exactly one root element, it becomes a TOML table with that root key. Nested elements become sub-tables, repeated elements become arrays. Attributes are preserved and appear - as in XML to JSON - with the @_ prefix; such keys and the text key #text are written as quoted keys in TOML.

This bridges markup and configuration: an XML record becomes a hand-editable .toml. It stays honest about it: well-formedness is checked before parsing, and invalid XML is rejected with a clear message. If a value cannot be represented in TOML, the tool reports it clearly instead of silently producing something wrong. Nothing is uploaded.

Specifications

In 3 steps

1. Drop or pick your XML file.
2. The tool converts it into TOML.
3. Download the TOML file.

Limitations: An XML document has exactly one root element, so a TOML table with that root key results. Nested elements become sub-tables, repeated elements become arrays. Attributes (@_) and element text content (#text) are written as quoted TOML keys. Number- and boolean-looking text is recognised as real TOML numbers/booleans (the same recognition XML to JSON already applies on read); XML comments are not captured while parsing and therefore do not appear in the TOML. Well-formedness is checked before parsing; invalid XML is rejected with a clear message. Values that cannot be represented are reported clearly.
