A short companion for TOML to YAML: when it is useful, what it expects, and what to check before using the result.

What it does

Convert TOML to YAML, turning tables into nested mappings and arrays of tables into sequences. Handy when a tool wants YAML but the config is written in TOML.

Use the tool

Open TOML to YAML, add the input the tool asks for, run it, and check the output before using it elsewhere.

Input and output

  • Input: text.
  • Output: text.
  • Category: Formats.

Privacy and processing

Processing happens locally in your browser. This tool does not upload the input to ilham.dev.

Questions

How are TOML dates represented?

As ISO 8601 strings. YAML does have a timestamp type, but writing one that other parsers agree on is unreliable, so plain strings are the safer output.
