Frequently asked questions

What is TOML used for?

TOML (Tom's Obvious, Minimal Language) is used for configuration files, especially in Rust projects (Cargo.toml), Python (pyproject.toml), and other tools.

How does TOML differ from YAML?

TOML is more explicit and less ambiguous than YAML. It uses clear key-value pairs and tables, making it easier to read and less error-prone.

Can it validate TOML syntax?

Yes, the formatter parses TOML and reports syntax errors, helping you debug configuration files before deployment.
