What this tool is for

Use this tool when you need to turn valid YAML into TOML that is easier to scan, share, or commit. Everything runs locally in the browser.

Where it helps

  • Converting API examples into TOML for docs or config files.
  • Rewriting copied YAML payloads into a format that is easier to diff by eye.
  • Preparing structured content for tools and workflows that expect TOML.

What to watch for

  • Input must be valid YAML in this tool.
  • The converter preserves data structure, but TOML presentation can still differ from hand-written style.
  • If you need to go the other direction, use the TOML to YAML converter instead.
