def flatten_json(nested_json, prefix=''):
    flat_dict = {}

        if isinstance(value, dict):
            flat_dict.update(flatten_json(value, prefix + key + '.'))

# Usage:
nested_json = {'name': 'John', 'address': {'city': 'New York', 'zip': '10001'}}
flatten_json(nested_json) # Returns: {'name': 'John', 'address.city': 'New York', 'address.zip': '10001'}
