Does the generated Python code compile in Python 3.10+?

Yes. By default, the generator outputs modern Python 3.10+ syntax with union pipes (e.g. str | None) and built-in generic collections (list[str]). If you need compatibility with Python 3.9, select 'Python 3.9' in the options panel.

How are Python reserved keywords handled?

If a JSON key conflicts with a Python reserved keyword (such as class, from, def, id, or type), the generator automatically appends a trailing underscore (class_, from_, id_) and maps it accurately in the from_dict and to_dict methods.

What is the JSON to Python Converter?

The PriyGop JSON to Python Converter transforms raw JSON structures into type-annotated Python classes or @dataclass models. It includes automatedfrom_dict() deserialization and to_dict() serialization methods, making it straightforward to parse external API payloads, JSON configs, and database records.

Python Type System & Features

@dataclass or Standard Class: Choose between modern boilerplate-free dataclasses or standard Python classes.
Python 3.10+ Pipes: Generates concise str | None and list[str] syntax by default, with an option for legacy typing.Optional.
Serialization Helpers: Generates recursive from_dict classmethods and to_dict methods for nested structures.
Reserved Keyword Escaping: Automatically escapes Python built-ins (e.g. id → id_, type → type_).

Dataclass with Serialization

@dataclass

Type hints with built-in dictionary conversion methods.

Example Syntax

from dataclasses import dataclass

@dataclass
class Profile:
    bio: str
    years_experience: int

    @classmethod
    def from_dict(cls, data: dict) -> "Profile":
        return cls(
            bio=data.get("bio"),
            years_experience=data.get("years_experience"),
        )

Eliminates tedious manual dictionary indexing and key error risks.
