TOML → XML for configuration handoffs
Reads TOML and writes it as XML elements inside a root element, with the same rules as JSON → XML.

Developer notes

The conversion goes through JSON, so it follows the rules of JSON → XML. Keys become child elements, never attributes. Array items are named after the parent key without its last letter, plus _item, so tags gives tag_item. Comments are dropped, and dates and times are written as ISO 8601 text. This pair has no output options. Namespace declarations are not written.

Use cases

Hand a Cargo or pyproject file to a system that only reads XML. Compare the shape of a TOML file with an XML schema. Preview how nested tables become elements.

About these options

CSV exports: choose a delimiter (Auto follows locale — semicolon on /fr), RFC-minimal vs always-quoted fields, line endings, and whether to emit a header row. CSV imports: delimiter is auto-detected from the first line (comma, semicolon, tab, or pipe) — toggle whether row 1 holds column names. JSON output (XML, YAML, or CSV sources): indentation (including compact one-line) and optional recursive key sort. JSON → XML: toggle pretty-printing and indent width. YAML output: indent width, readable vs tighter layout, and deterministic string quoting (there is no source YAML file to “preserve”). XML comments are not represented in the intermediate JSON tree.

Examples

Package and dependencies

Input

[package] name = "fastminify-cli" version = "2.1.0" edition = "2021" [dependencies] serde = { version = "1.0", features = ["derive"] } tokio = "1.35"

Output

<?xml version="1.0" encoding="UTF-8"?> <root> <package> <name>fastminify-cli</name> <version>2.1.0</version> <edition>2021</edition> </package> <dependencies> <serde> <version>1.0</version> <feature_item>derive</feature_item> </serde> <tokio>1.35</tokio> </dependencies> </root>

Array, root key and table

Input

title = "Release" tags = ["stable", "lts"] [owner] name = "Platform team"

Output

<?xml version="1.0" encoding="UTF-8"?> <root> <title>Release</title> <tag_item>stable</tag_item> <tag_item>lts</tag_item> <owner> <name>Platform team</name> </owner> </root>

TOML → XML FAQ

Rules of the output

Are attributes written?

No. Every key becomes a child element.

How are arrays written?

Each item becomes an element named after the parent key without its last letter, plus _item, and the parent tag is dropped.

What happens to TOML dates?

They are read as dates and written as ISO 8601 text inside the element.

Is my data sent to a server?

No. The conversion runs in your browser, and FastMinify never receives what you paste.
