The output below was generated by the same conversion code the converter uses, run on this sample when the page was built.
[cargo.package]

version = "0.3.2"
edition = "2021"
[cargo.dependencies]
serde = "1.0"
tokio = "1.40"
[cargo.profile.release]

</cargo>XML output is 83% larger than the TOML input. The same data is 175 characters as minified JSON and 291 as pretty-printed JSON. Sizes are character counts, not tokens: token counts depend on the model's tokenizer (see the tokenizer comparison).
TOML to XML: what changes
- Reading TOML: A TOML document always parses to a table (an object), never a bare array. Datetimes are a TOML-native type and come out as ISO 8601 strings.
- Writing XML: XML needs exactly one root element. Several top-level keys, or a top-level key holding an array, produce sibling roots that are not well-formed XML, which is why this sample is wrapped in a single key. Keys prefixed with @_ become attributes.
About TOML
TOML is a config file format with explicit types. It's the official format for Python's pyproject.toml and Cargo's Cargo.toml.
- ✓Explicit types
- ✓Standard in Python/Rust
- ✓Unambiguous
- ✓Easy to parse
About XML
Extensible Markup Language is a verbose but powerful format. Still widely used in legacy systems, SOAP APIs, and document formats.
- ✓Rich metadata
- ✓Namespaces
- ✓Validation schemas
- ✓Legacy support
Why Convert TOML to XML?
Use XML when working with legacy systems, SOAP APIs, or when you need rich metadata and validation schemas.
