What is TOML?
TOML (Tom's Obvious, Minimal Language) is designed to be a highly readable and straightforward configuration file format. It maps cleanly to a hash table, making it a favorite for modern packaging and build systems such as Rust's Cargo.toml and Python's pyproject.toml. Using a formatter ensures consistent structure, clean spacing, and strict adherence to syntax specifications.
Frequently Asked Questions (FAQ)
Absolutely. All formatting and validation execution runs completely inside your browser using client-side JavaScript libraries. No configuration text is transmitted to external servers.
This tool relies on robust JavaScript TOML parsing engines to parse your structures into native objects before cleanly serializing and validating them back into clean text.
