Comment utiliser

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.

Questions fréquentes
