I want to convert Json file to csv file using Pyhton

I have problem when i convert json file to csv
i convert my csv file to json and it work
but when i convert json file to csv file it don’t work!

HERE MY PYTHON CODE

   with open('orders.json') as json_file:
    data = json.load(json_file)
 
    order_data = data['orders']

    # now we will open a file for writing
    data_file = open('data_file.csv', 'w')

    # create the csv writer object
    csv_writer = csv.writer(data_file)

    # Counter variable used for writing
    # headers to the CSV file
    count = 0

    for ord in order_data:
        if count == 0:

            # Writing headers of CSV file
            header = ord.keys()
            csv_writer.writerow(header)
            count += 1

        # Writing data of CSV file
        csv_writer.writerow(ord.values())

    data_file.close()

and the output is like this

there null row on the csv file how to handle this problem?

and here the json file

>Solution :

In Python 3 the required syntax changed and the csv module now works with text mode 'w', but also needs the newline='' (empty string) parameter to suppress Windows line translation (see documentation links below).

with open('/pythonwork/thefile_subset11.csv', 'w', newline='') as outfile:
    writer = csv.writer(outfile)
