What Is YAML to TOML Converter?
YAML to TOML Converter transforms YAML configuration files into TOML format. TOML (Tom's Obvious Minimal Language) is increasingly popular for configuration files in Rust, Go, and Python projects. This tool handles scalars, nested tables, arrays, and array-of-tables.
How to Use
- Paste your YAML into the input area
- The TOML output appears instantly on the right
- Copy the result with the Copy button
Features
- Converts scalars, nested objects (TOML tables), and arrays
- Array-of-tables support using
[[table]]syntax - Preserves types: strings, integers, floats, booleans
- Runs entirely in the browser — no server required
FAQ
What YAML features are supported?
This tool handles the most common YAML patterns: scalar values, nested mappings, and sequences. Advanced features like anchors, aliases, multi-document streams, and block scalars are not supported.
How are YAML nulls handled?
YAML null and ~ are converted to empty strings in TOML, since TOML has no native null type.
When should I use TOML over YAML?
TOML is stricter and less whitespace-sensitive than YAML, making it less error-prone for configuration files. It is the default format for Rust's Cargo.toml and Python's pyproject.toml.
