Convert TOML to XML online, free. TOML is a readable configuration format built around key/value pairs and tables. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. TOML to XML conversion parses your TOML against the TOML v1.0.0 grammar (https://toml.io/en/v1.0.0), builds an in-memory model of its keys, nested objects and arrays, then re-serializes it as valid XML following the W3C XML 1.0 conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include SOAP web services, RSS/Atom feeds and legacy enterprise documents.
It maps the full structure of your TOML onto well-formed XML, following the W3C XML 1.0 conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste TOML and convert XML immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested TOML objects, tables and arrays are mapped faithfully onto XML.
Your TOML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A TOML document and its XML equivalent:
TOML input:
name = "Alice"
age = 30
email = "[email protected]"Output:
<user>
<name>Alice</name>
<age>30</age>
<email>[email protected]</email>
</user>Paste your TOML into the editor and press "Convert to XML". The tool parses it against the TOML v1.0.0 grammar, then re-serializes it as XML following W3C XML 1.0 conventions — instantly and entirely in your browser. You can validate or format the TOML first to be sure it is clean.
TOML values are typed and it has first-class dates and times, so they carry into XML cleanly. TOML tables become nested XML structures, and arrays-of-tables become lists.
Numbers, booleans and null are preserved as native XML types wherever XML supports them, so standard documents convert losslessly and can be read back into the same structure.
TOML (Tom's Obvious Minimal Language) (TOML) — TOML is a readable configuration format built around key/value pairs and tables. XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. This converter maps the structure of your TOML onto XML so you can use it for SOAP web services.
Yes. Invalid TOML is flagged with a clear error before anything is converted. Common TOML problems to check are correct key/value pairs, quoted strings, and valid [table] headers. Starting from clean input keeps the generated XML accurate.
Yes. The entire TOML-to-XML conversion runs locally in your browser in JavaScript — your TOML is never uploaded, logged or stored. That matters when the data is something like Rust Cargo & Python pyproject config, which should not leave your machine.
The generated XML is ready for SOAP web services, RSS/Atom feeds and legacy enterprise documents. Copy or download it and drop it straight into your tooling.
TOML to XML conversion parses a TOML configuration document and emits the equivalent XML. TOML ("Tom's Obvious Minimal Language") is a readable config format built around key/value pairs and tables, while XML (eXtensible Markup Language) is a widely supported, self-describing markup format used in SOAP services, legacy systems, and document pipelines. This tool parses TOML to the TOML v1.0.0 spec and wraps the result under a single root element, producing well-formed, indented XML entirely in your browser.
XML requires exactly one root element, while TOML documents can have several top-level tables. The converter wraps everything under a single <root> element so the output is always well-formed.
The data (keys, values, tables, arrays) maps over faithfully. TOML comments are not preserved, since XML represents them differently and they carry no structural data.
No. Conversion runs entirely in your browser — your data never leaves your device.
