Quick tips for Python dict conversion
# Python dict input
{
'name': 'Maeve Winters',
'age': 28,
'active': True,
'tags': ('developer', 'backend'),
'metadata': None
}
// JSON output
{
"name": "Maeve Winters",
"age": 28,
"active": true,
"tags": ["developer", "backend"],
"metadata": null
}Work with Python data structures and JSON using these complementary conversion and code generation tools.
Format and validate the JSON output for better readability.
Generate Python dataclasses or Pydantic models from JSON for the reverse workflow.
Create JSON Schema definitions from converted JSON for validation and documentation.
Generate TypeScript interfaces from JSON for frontend development.
Supports standard Python dictionary and list syntax including single quotes, None, True/False values, nested structures, and tuples (converted to arrays).
None → null, True/False → true/false, single quotes → double quotes, tuples → arrays. Numbers and strings are preserved with proper JSON formatting.
Yes. You can paste Python dict definitions, list results, or any Python data structure that evaluates to a dict or list.
Only basic data types are supported: dict, list, tuple, str, int, float, bool, None. Custom objects need to be converted to basic types first.
Yes, all data processing happens entirely in your browser. Your Python data is converted locally and never sent to any server, ensuring completely private and secure conversion.
