What Is TOML to XML Conversion?

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.

How to Use the TOML to XML Converter

  • Paste your TOML into the input, or load the example.
  • Click Convert to XML to parse and transform it.
  • Copy the XML or use it directly in your code, API, or config.

What the Converter Handles

  • Tables & nested keys: TOML tables and dotted keys become nested XML elements under the root.
  • Typed values: numbers, booleans, and dates are carried through as element text.
  • Arrays: array values are emitted as repeated child elements, the natural XML representation of a list.

Frequently Asked Questions

Why does the XML have a single root element?

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.

Is TOML to XML conversion lossless?

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.

Is my TOML uploaded to a server?

No. Conversion runs entirely in your browser — your data never leaves your device.
