Frequently asked questions
Which TOML version is supported?
TOML 1.0, including tables, arrays of tables, inline tables, and dates.
What happens to TOML dates in JSON?
They become ISO 8601 strings, since JSON has no date type.
Can every JSON file become TOML?
Almost. TOML needs an object at the top level and has no null, so JSON with a top-level array or null values can't be represented.
