Fix Python 'None', 'True', 'False' in JSON

Repair JSON created from Python dictionaries. Convert True to true, False to false, and None to null.

Problem Example

This invalid JSON will cause parsing errors

{
  "is_valid": True,
  "results": None
}

Why This Happens

Python's boolean and null values are capitalized (True, False, None), while JSON requires lowercase literals (true, false, null).

About JSON Standard

JSON (JavaScript Object Notation) is a strict data interchange format. Unlike JavaScript objects, JSON requires:

All keys must be enclosed in double quotes
String values must use double quotes (not single quotes)
No trailing commas after the last item
No comments allowed
Proper escaping of special characters
