Code generation
JSON to Python
Generate Python dataclasses from JSON locally.
What is JSON to Python?
Infer Python dataclasses from a JSON example in your browser. Nested objects become their own dataclasses, fields are typed from the sample values, and the result is ready to paste straight into a Python module — no server round-trip required.
How to use JSON to Python
- Paste or type your input into the editor.
- Use the tool action to process your data in the browser.
- Review the output, then copy or download it if needed.
Key features
- Private browser-based processing.
- No account or login required.
- Works without uploading your data.
- Fast results for common developer tasks.
Frequently asked questions
Is JSON uploaded?
No. Generation runs in your browser.
How are nested objects handled?
Each nested object in your JSON example becomes its own dataclass, referenced as a field type on the parent dataclass.
Does it require any external libraries?
No. The generated code uses only the standard library's dataclasses module, so it works without extra installs.
