TOML vs YAML

TOML and YAML are both human-readable configuration formats, but have different strengths. TOML (used by Cargo.toml, pyproject.toml) has stricter typing and an unambiguous spec; YAML (used by GitHub Actions, Kubernetes, Docker Compose) is more expressive but has subtleties (e.g. implicit booleans, tabs vs spaces). This converter parses TOML into an intermediate object and serialises it with js-yaml. Related: TOML to JSON · YAML to TOML.
