Why use a private YAML to TOML converter?
Moving YAML configs to TOML for Rust, Python, or Hugo is a common migration task. This converter handles it entirely in your browser — no data is uploaded or transmitted.
How it works
js-yaml parses the YAML input. The root must be a YAML mapping (object) since TOML requires a root table. The converter maps YAML sequences of mappings to TOML arrays of tables and serializes the result to TOML format.
Common use cases
- Migrating GitHub Actions or Kubernetes YAML configs to TOML for Rust tooling
- Converting YAML front matter in Markdown files to TOML for Hugo
- Translating YAML config files to TOML for pyproject.toml or Cargo.toml
Frequently asked questions
- Is my data safe to convert here?
- Yes. All conversion happens in your browser. No data is transmitted to any server.
- Why must the YAML root be a mapping?
- TOML requires a root table (object). A YAML sequence at the root has no direct TOML equivalent.
