TOML

Tom's Obvious Minimal Language

TOML is a configuration format designed to be unambiguous where YAML is subtle: no significant whitespace, explicit table headers, typed values. Rust (Cargo), Python packaging (pyproject.toml) and Hugo all use it.

Extension: .toml
MIME type: application/toml

Opening a .toml file

If you landed here because something handed you a .toml file and nothing on your machine will open it, converting it to a format you already have a reader for is usually faster than installing new software. Every conversion above runs in this browser — the file is not uploaded, so it works on a locked-down work machine and on a file you are not allowed to send anywhere.
