TOML Formatter
Format and beautify TOML configuration files with proper structure and validation.
What is TOML?
TOML (Tom's Obvious, Minimal Language) is a configuration file format designed to be easy for humans to read and write. It’s commonly used in modern tooling and build systems—like Python projects (pyproject.toml), Rust (Cargo.toml), and many app configuration setups.
TOML uses simple key/value pairs and sections (tables) like [database] to group related settings. Keeping TOML consistently formatted helps reduce mistakes and makes diffs easier to review.
