About JSON to TOML Converter
TOML is a configuration format built to be obvious to read, and it is what Cargo.toml, pyproject.toml and netlify.toml use. It maps onto the same shapes as JSON - tables become objects, arrays become arrays - so most documents convert cleanly in both directions.
Two differences are worth knowing. TOML has no null, so keys with a null value are left out and listed for you rather than silently dropped. And TOML cannot have an array at the top level, so a JSON document that starts with [ needs wrapping in an object first.
