Why should I convert TOML to JSON?

TOML is a human-readable config format, but many web APIs, JavaScript apps, and SaaS tools require JSON. By converting TOML to JSON, you ensure compatibility with these systems. JSON also strips comments (which TOML supports), reducing file size and speeding up data transfer.

What happens to TOML's data types during conversion to JSON?

TOML tables become JSON objects, arrays become JSON arrays, and integers, floats, booleans, and strings are preserved. Datetimes (RFC 3339) are converted to ISO 8601 strings because JSON has no native date type. Nested tables and arrays of tables are converted to nested objects and arrays. Comments are not retained as JSON does not support them.
