FAQ
When would I convert TOML to YAML?
Common scenarios: migrating a Rust/Hugo project config to a Kubernetes or Docker Compose setup, or adapting a Cargo.toml dependency list for a CI/CD pipeline that expects YAML.
Are TOML arrays of tables supported?
Basic arrays and inline tables are supported. Complex multi-line arrays of tables ([[array]] syntax) may require manual adjustment after conversion.
Does YAML preserve TOML types?
Yes — numbers stay numbers, booleans stay booleans, and strings are quoted only when necessary to avoid ambiguity.
