JSON to TOML

Convert JSON objects into TOML for configuration files. Nested JSON objects become TOML sections, and arrays of objects become array tables.

JSON is convenient for APIs and generated data, but TOML is often easier to edit by hand. Converting JSON to TOML can help when moving settings into a project config file or writing readable examples for documentation.

TOML works best with object-shaped data. Deeply mixed arrays or values that do not have a natural TOML representation may need a small cleanup pass after conversion.

The output uses standard section headings for nested objects, which makes it easier to review related settings together.
