Online TOML to YAML Converter

What is TOML?

TOML (Tom's Obvious, Minimal Language) is a configuration file format designed to be easy to read and write. It maps to a hash table and is often used for project configuration files such as Cargo.toml (Rust), pyproject.toml (Python), and Hugo configs. TOML supports tables, arrays of tables, inline tables, multi-line strings, and typed values like integers, floats, booleans, and datetimes.

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files, CI/CD pipelines, Kubernetes manifests, and Docker Compose files. YAML uses indentation-based nesting, supports complex data structures, and is widely adopted across DevOps tooling.

Why Convert TOML to YAML?

Converting TOML to YAML is useful when migrating configurations between tools that use different formats. For example, you might have a TOML-based config that needs to be adapted for a Kubernetes deployment (YAML) or an Ansible playbook. This converter lets you quickly transform your data without manual rewriting.
