Convert YAML to TOML online, free. YAML is an indentation-based superset of JSON favoured for human-edited config. TOML is a readable configuration format built around key/value pairs and tables. YAML to TOML conversion parses your YAML against the YAML 1.2.2 grammar (https://yaml.org/spec/1.2.2/), builds an in-memory model of its keys, nested objects and arrays, then re-serializes it as valid TOML following the TOML v1.0.0 conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include Rust Cargo & Python pyproject config, app settings files and tool configuration.
It maps the full structure of your YAML onto well-formed TOML, following the TOML v1.0.0 conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.

YAML (YAML Ain't Markup Language) (YAML) and TOML (Tom's Obvious Minimal Language) (TOML) are different serialization formats, each with its own syntax and strengths. Data often needs to move between them when integrating tools, APIs, or configuration systems that expect a specific format. This converter maps the structure of your YAML onto valid TOML so you can use it wherever TOML is required.
