What Is TOML to XML?
You've got a tidy TOML config — maybe a Cargo.toml or pyproject.toml — and somewhere downstream a system only speaks XML. That gap is annoying. TOML tables become XML elements, arrays become repeated nodes, and the whole thing runs in your browser. Nothing leaves your machine, so it's fine to use with real configs. The TOML specification defines the input rules; the W3C XML standard defines the output.
This tool runs entirely in your browser. Nothing is sent to a server. Paste TOML or upload a file; get XML output. For TOML to JSON, use TOML to JSON. For TOML to YAML, use TOML to YAML. For the reverse, use JSON to TOML.

Copy or Download
Use Copy or Download to get the XML. For formatting XML, use XML Formatter. For validation, use XML Validator.
When TOML to XML Helps
When integrating TOML config with XML-based systems, legacy APIs, or SOAP services, convert here. Cargo and Poetry use TOML; convert to XML when feeding enterprise systems. For JSON or YAML output, use TOML to JSON or TOML to YAML. For CSV, use TOML to CSV.
Frequently Asked Questions
Is my data private?
Yes. Everything runs in your browser — nothing is sent to any server. Open your browser's Network tab while using the tool to confirm.
How does TOML map to XML structure?
TOML tables become XML elements, keys become child elements, and nested tables become nested elements. The W3C XML spec governs the output format.
Are TOML comments kept in the XML?
XML supports comments, but most TOML parsers discard comments during parsing. If comment preservation matters, add them manually to the XML output.
Can I convert nested TOML tables?
Yes. Nested TOML tables map to nested XML elements, preserving the hierarchy.
What happens with TOML arrays?
TOML arrays become repeated XML child elements under the same parent tag. Check the output to see if it matches your target schema.
