def convert_to_json(data: dict, filename: str, position: str = None) -> None:
    """
    Converts a dictionary to a JSON file and saves it at a specified location.

    Args:
        data (dict): The data to be converted into JSON format.
        filename (str): The name of the output JSON file, without the '.json' extension.
        position (str, optional): The file path where the JSON file should be saved. Defaults to the directory of the caller script if not provided.

    Returns:
        None: The function does not return anything.
        
    Raises:
        ValueError: If 'filename' contains '.json'.
        FileNotFoundError: If the specified directory does not exist.
        PermissionError: If write permissions are lacking for the directory.

    Example:
        >>> convert_to_json({'id': [1, 2], 'value': [10, 20]}, 'output', '/path/to/save')
        Saves a JSON file named 'output.json' at '/path/to/save'.

    Notes:
        This function automatically ensures the directory exists before attempting to write the file. If the directory does not exist, it will attempt to create it.
