What is XML to TOML Conversion?

XML to TOML conversion takes a hierarchical XML document and rewrites it in TOML, a config language designed to be obvious to read. XML uses opening and closing tags; TOML uses sections in square brackets, key-value pairs with equals signs, and explicit types. A xml to toml converter walks your XML tree and writes the same data with far cleaner syntax. If you've worked with Rust (Cargo.toml) or modern Python (pyproject.toml), you've already used TOML.

Why Convert XML to TOML?

TOML is the format of choice in modern toolchains: Rust's Cargo, Python's Poetry and Hatch, Hugo, and a long list of Go and Rust projects. A lot of legacy config still lives as XML, but the tools you're feeding it into now expect TOML. Converting xml to toml online is the fastest way across without retyping nested elements by hand. Use a xml to toml tool when you need to migrate XML configs to TOML-based projects, generate Cargo.toml or pyproject.toml from older config files, modernize legacy settings into a strongly-typed format, or sync XML data into TOML for tools that read it.

How Our XML to TOML Converter Works

When you click Convert, the tool parses your XML, walks the tree, and writes it out using TOML syntax. Top-level child elements become [section] headers, nested elements become nested tables, and repeated tags become arrays of tables ([[section]] blocks). Strings are quoted, numbers and booleans are auto-detected, and attributes are preserved as keys alongside the element values. Everything runs in your browser. Your XML data is not uploaded to any server.

Features You Get

  • Section detection: top-level XML elements with children automatically become TOML tables.
  • Type preservation: numbers, booleans, and dates are detected and written with the right TOML syntax.
  • Array of tables support: repeated elements become [[section]] blocks for clean lists of records.
  • Attribute preservation: XML attributes are kept as TOML keys alongside the element values.
  • Upload support: load a .xml file from your device or drag-and-drop it into the input.
  • One-click copy: grab the TOML output with the Copy button and paste it into your config file.

How to Use the Tool

  1. Paste your XML into the input editor, or use the Upload File button to load a .xml file.
  2. Click the Convert button to generate the TOML output on the right.
  3. Verify the section headers and table-array blocks match what your tool expects.
  4. Click the Copy button to copy the TOML to your clipboard.

Common Use Cases

  • Config modernization: moving XML configs into TOML-based projects without retyping.
  • Rust and Python projects: generating Cargo.toml or pyproject.toml entries from older XML.
  • Static site generators: migrating XML data to Hugo or Zola TOML config.
  • Strongly-typed configs: moving from untyped XML to TOML's typed format for fewer surprises.

Example Conversion

Input (XML)

<config>
  <server>
    <host>localhost</host>
    <port>3000</port>
  </server>
</config>

Output (TOML)

[config.server]
host = "localhost"
port = 3000
