Frequently asked questions

Why TypedDict instead of dataclass?

TypedDict describes dictionary shapes exactly as JSON decodes them, so it matches json.loads output without conversion.

What about keys that aren't valid identifiers?

Keys like 'first-name' use the functional TypedDict(...) syntax so any string key is supported.

Is the output final?

Treat it as a starting point — verify Optional fields and numeric types, since they are inferred from a single sample.
