JSON to Pydantic Model

Generate Pydantic v2 BaseModel classes from a JSON sample. Field types are inferred (str, int, float, bool, list, datetime, EmailStr). Nested objects become nested classes. Output is ready to drop into a Python file.

How to use the JSON to Pydantic Model

Paste a JSON sample. The generator infers Python types and writes a Pydantic class for the root object plus one for each nested object. Output uses Pydantic v2 syntax (the current major version). Imports needed are listed at the top of the output.
