About Python to JSON Converter
Convert Python object text output to standard JSON. Supports the following syntax conversions:
1. Single quotes → Double quotes — e.g.,
{'name': 'Alice'} becomes {"name": "Alice"}
2. True/False/None → true/false/null — Python booleans and None converted to JSON standard
3. Tuples () → Arrays [] — e.g., (1, 2, 3) becomes [1, 2, 3]
4. Trailing comma removal — e.g., extra commas in {"a": 1,} are automatically removed
Perfect for developers who need to quickly convert Python debug output (print/repr/pprint), log data, or REPL results to standard JSON. All processing happens locally in your browser.Frequently Asked Questions
What Python syntax does this tool handle?▼
It converts single quotes to double quotes, replaces True/False/None with true/false/null, converts tuples () to arrays [], and removes trailing commas.
Can it handle nested Python dicts?▼
Yes, the converter recursively processes all nested dictionaries, lists, and tuples, converting them to their JSON equivalents.
What about Python-specific types like sets or datetime?▼
The tool handles the most common repr output patterns. Complex Python types like sets, datetime objects, or custom class repr() output may not be fully supported — those require manual adjustment.
