Python Dict to JSON Converter

Convert Python dictionaries to valid JSON

JSON is used when Python data needs to travel between applications: browser requests, REST APIs, configuration files and databases all rely on it. A Python dictionary looks close to JSON, but it is not always valid JSON. This tool converts common Python literals into a clean JSON document.

Key differences to remember

Python True, False and None become true, false and null.
JSON requires double quotes around text keys and string values.
Tuples, dates and custom objects need to be converted to supported JSON values before serialization.

Example

A Python value such as {'project': 'json2py', 'published': True, 'version': None} becomes {"project":"json2py","published":true,"version":null}. The formatted output is easier to inspect or copy into an API client.

When to use code instead

For production applications, use Python's built-in json.dumps(). This page is intended for quick inspection, debugging and converting small snippets. Do not paste credentials, private keys or confidential customer data into any online tool.
