Does this support nested tables?

Yes. Standard tables ([section]), nested dotted keys, and inline tables are all converted to nested XML elements.

How are TOML arrays converted?

Each array element becomes a repeated child element with the key name. For example, ports = [80, 443] becomes two elements inside the parent element.

Are dates and times supported?

Basic ISO 8601 date-time literals are preserved as text content in the XML element. Full TOML date-time offset parsing is included.

Is my data sent to any server?

No. The entire conversion runs inside your browser using JavaScript. No data is transmitted anywhere.

What XML root element is used?

The root element is by default. All top-level TOML keys and tables become direct children of .

Can I open the converted XML in Word or Notepad++?

Yes. The output is standard, well-formed XML — open it in any text editor (Notepad++, VS Code), an IDE, or Microsoft Word, or feed it to any XML parser.

Summary

Paste TOML on the left and get well-formed XML on the right — instant, client-side, no data leaves your browser.

How it works

Paste your TOML into the left panel, or click Load Sample to see an example.
A JavaScript TOML parser reads the input and builds an in-memory tree of tables, arrays, and values.
The tree is serialized to indented, well-formed XML in the right panel.
Copy the XML or download it as a file — all processing stays in your browser.

Use cases

Convert a TOML config to XML so a legacy tool or Java library can consume it.
Quickly inspect the structure of a TOML file as a readable XML tree.
Cross-check TOML parsing when building a multi-format config pipeline.
Generate XML fixtures for tests from TOML source files.
