JSON to Python Dict Generator

Automatic mapping: string→str, number→int/float, boolean→bool, null→None, array→list, object→dict. ISO date strings in JSON are automatically converted to datetime objects. Nested objects are recursively processed into full dict structures.

Yes. The generated code uses standard Python dict literal syntax and can be copied directly into your Python project. Compatible with Python 3.6+. The plain dict mode works with Python 2.7+ as well. No external dependencies required.

JSON null values are converted to Python's None keyword. In 'typed annotation' mode, null fields are marked as Optional[Any]. The tool also supports replacing nulls with default empty values via configuration options.

Fully supported. Nested objects are recursively converted to Python nested dict structures, preserving the hierarchical relationships and indentation of the original data. Objects in arrays are also handled correctly.

Absolutely. This tool runs 100% in your browser. Your JSON data is processed entirely in local memory and never uploaded to any server. Once processed, the data is immediately cleared. The tool works offline as well.
