How to Convert Python to JSON - Step by Step Guide

Step 1

Input Your Python Code

Start by pasting your Python dictionary, class instantiation, or list that needs to be converted to JSON format. The tool supports Python dict literals, class constructors with keyword arguments, and nested structures.

•
Paste Python code: Copy your Python dictionary or class instantiation directly into the editor
•
Upload a file: Load Python code from a .py or .txt file on your computer
•
Try samples: Click sample buttons to see different Python patterns (dict literals, class instances, lists, nested structures)

Example: Python Dictionary/Class

Here's a typical Python dictionary:

person = {
    'name': 'Lydia Hart',
    'age': 28,
    'is_active': True,
    'roles': ['admin', 'user']
}
Step 2

Click Convert Button

Click the green "Convert" button to send your Python code to our backend API for processing. The converter uses tree-sitter AST parsing to transform Python syntax to JSON format, handling True/False, None values, single quotes, and proper formatting.

•
Boolean conversion: Python True/False becomes JSON true/false
•
None handling: Python None converts to JSON null
•
Quote standardization: Single quotes ('') become double quotes ("") for JSON compliance
•
Class instantiation: Python class constructors convert to JSON objects
•
Nested structures: Handle complex Python data hierarchies with nested objects and arrays

Example: Converted JSON Output

The same data in JSON format:

{
  "name": "Lydia Hart",
  "age": 28,
  "is_active": true,
  "roles": [
    "admin",
    "user"
  ]
}
Step 3

Get Valid JSON Output

The tool produces properly formatted, valid JSON that's ready to use in your applications, APIs, or configurations.

•
Real-time validation: Green checkmark confirms your JSON is syntactically correct
•
Proper formatting: Beautified with correct indentation and structure
•
Ready for APIs: Use directly in Flask, Django, FastAPI responses or database storage
Step 4

Copy or Download JSON

Copy the JSON to your clipboard or download it as a .json file for use in your Python projects, web applications, or REST APIs.

•
Copy to clipboard for immediate use
•
Download .json file for integration into your codebase
•
Use in Python frameworks: Perfect for Flask, Django, FastAPI, and modern Python APIs
•
Export options: Convert to readable tables or minify for production

What is Python to JSON Conversion?

Python to JSON conversion transforms Python data structures like dictionaries, lists, and class instances into standard JSON format. This process converts Python-specific syntax (True, False, None, single quotes) into JSON-compliant syntax (true, false, null, double quotes) for data interchange and API communication.

The conversion is essential for Python web frameworks like Flask, Django, and FastAPI where JSON is the standard format for REST API responses. You can also convert other languages like C# to JSON or Java to JSON using our related tools.

Frequently Asked Questions

How do I convert Python dictionary to JSON?

Simply paste your Python dictionary or class instantiation into the converter. It will automatically convert Python syntax (True, False, None, single quotes) to valid JSON format (true, false, null, double quotes).

Does the converter handle nested Python structures?

Yes! The converter properly handles nested dictionaries, lists, class instances, and mixed data structures, converting them to equivalent JSON representations while maintaining the structure.

What Python types are supported?

The converter supports Python dictionaries, lists, class instances with keyword arguments, strings, numbers, booleans (True/False), and None. These are converted to their JSON equivalents: objects, arrays, strings, numbers, booleans, and null.

Is the output valid JSON?

Yes! The converter produces standard, valid JSON that can be used in any application or API. The output is properly formatted and validated.

Is the Python to JSON converter free?

Yes, completely free with no limitations on data size or conversion frequency. No registration required.
