How it works

β–  What is YAML? YAML (YAML Ain't Markup Language) is a human-readable format that uses indentation for hierarchy. Widely used in Kubernetes manifests, CI/CD (e.g. GitHub Actions), Docker Compose. β–  What is TOML? TOML (Tom's Obvious, Minimal Language) is a human-readable format for config files. It supports key=value, [sections], arrays, dates, numbers, and booleans. Widely used in Rust (Cargo.toml), Python (pyproject.toml). β–  How conversion works The tool parses YAML into an object and serializes it to TOML. All processing runs in the browser.
