What Gets Converted
This free online tool intelligently converts Python dictionary syntax to JSON format by handling all the differences between Python and JSON notation. It supports single quotes, None/True/False values, tuples, trailing commas, and even evaluates string representations of dictionaries.
None→nullTrue/False→true/false'single quotes'→"double quotes"(tuples)→[arrays]- Trailing commas are removed automatically
- Comments are stripped from output
Best Practices
Copy from Python: Paste dict literals, parsed objects, or even __repr__ output directly.
Test APIs: Convert Python fixtures to JSON for REST API testing or mock data generation.
Data Migration: Transform Python config files or data structures to JSON for cross-platform use.
Documentation: Generate clean JSON examples from Python code for API documentation.
