What draft version does it use?
It generates schemas compatible with Draft 7, which is widely supported by most JSON Schema validators and tools.
Does it handle arrays?
Yes, it infers the types of items in an array. If items have different types, it creates a list of possible types or uses a more general schema.
Are required fields identified?
Yes, by default it treats all top-level properties found in the JSON as required, but you can easily modify this in the output.
