Frequently Asked Questions
What Python version is targeted?▼
The generator targets Python 3.10+ using `from __future__ import annotations` for PEP 604 union syntax (Optional[T] becomes T | None).
How are null values handled?▼
When nullable field detection is enabled, fields with null values are typed as Optional[T] (or T | None with PEP 604 syntax), and the field default is set to None.
Is my data sent to a server?▼
No. All conversion happens locally in your browser.
