What Is XML to TOML?

Got an XML config or API response you need in TOML format? TOML is the config language of choice for Rust Cargo and Python Poetry — but XML-heavy systems still produce data that needs converting. This tool reads your XML following the W3C XML 1.0 spec, flattens nested elements into TOML tables, and outputs clean, ready-to-use TOML. You can parse the result with browser-native DOMParser or any TOML library. The XML is parsed and the TOML written on this page itself, so the document never leaves your machine.

How to Use This Tool

1

Paste or Upload XML

Paste XML or upload a file. Use Sample for example data.

2

Review TOML Output

The right panel shows converted TOML. Nested elements become TOML tables.

3

Copy or Download

Use Copy or Download. For JSON to TOML, use JSON to TOML. For XML formatting, use XML Formatter.

When XML to TOML Helps

When migrating from XML-based systems to TOML config (e.g. for Cargo, Poetry), convert here. XML from SOAP, feeds, or enterprise APIs can be flattened to TOML tables.

Frequently Asked Questions

When should I use TOML instead of XML?

TOML is human-friendly, minimal, and great for config files — it is the default for Cargo.toml and pyproject.toml. XML is better for document-centric data, SOAP APIs, or when you need attributes and namespaces.

How does XML map to TOML?

Nested XML elements become TOML tables. Repeated elements become arrays of tables ([[table]]). Text-only nodes become string keys. Attributes are mapped to keys under the parent table.

Can I use this for Cargo.toml or pyproject.toml?

Yes. Generate the TOML here, then copy it into your Cargo.toml or pyproject.toml. You may need to adjust section headers to match Cargo or Poetry conventions.

Is my data sent anywhere?

No. The page parses the XML and builds the TOML with JavaScript on your own machine. Your XML never travels over the network at any point.
