YAML to TOML Converter

Summary

Paste YAML on the left, get clean TOML on the right — instantly, in your browser.

How it works

1. Paste or type your YAML into the left panel.
2. The tool parses the YAML using js-yaml.
3. It then serializes the parsed data tree into valid TOML.
4. The converted TOML appears instantly in the right panel.
5. Click Copy to copy the TOML output to your clipboard.

Use cases
