Verwendung

Generate Python types

Paste a sample object and run Convert. The output imports typing helpers and defines a class per nested object.

  1. Paste a JSON object.
  2. Click Convert.
  3. Copy the Python code into your project.

Type mapping

Strings become str, integers int, decimals float, booleans bool, arrays List[T] and nested objects their own TypedDict class.

Häufige Fragen

Why TypedDict instead of dataclasses?

TypedDict describes plain dictionaries produced by json.loads without requiring conversion, which matches typical JSON handling.

How are null values typed?

They are typed as Any because null carries no type information.
