TOML to YAML Converter
The TOML to YAML converter transforms TOML configuration files into clean, readable YAML. TOML is widely used in the Rust ecosystem (Cargo.toml), Python packaging (pyproject.toml), and Go projects, while YAML dominates in DevOps tooling like Docker Compose, Kubernetes, and Ansible. This tool bridges the two formats for easy migration and interoperability.
The converter handles all common TOML constructs: key-value pairs, tables (sections), arrays of tables, inline tables, arrays, strings (basic and literal), integers, floats, and booleans. TOML's table headers like [database] become nested YAML objects, and arrays of tables like [[dependencies]] become YAML arrays.
This is particularly useful when migrating project configurations between ecosystems — for example, converting a Rust project's Cargo.toml into YAML for documentation, or transforming a pyproject.toml into YAML for integration with CI/CD pipelines that expect YAML input. All processing happens locally in your browser.
