A short companion for YAML to TOML: when it is useful, what it expects, and what to check before using the result.
What it does
Convert YAML to TOML, preserving nesting, arrays and types. TOML has no null, so a null value is reported rather than quietly dropped or turned into an empty string.
Use the tool
Open YAML to TOML, 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
What happens to a null value?
TOML has no null type, so it cannot be represented. The converter tells you which key it was, so you can decide what the absence should mean.
Does key order survive?
Yes, and it matters in TOML, because keys have to be defined before any table that uses them. The converter keeps the order it was given.
