Excel экспорт и тестирование файла Excel API

Question

Я тестирую drf api, который принимает файл Excel в качестве входных данных.поэтому я хочу создать книгу Excel с именем Sheet1, потому что мой API написан в этом формате, и после создания книги я сохраняю в своем приложении, но я не могу указать путь к нему, чтобы мой API мог взять файл Excel

, как будто рабочая книга создается и сохраняется в моем приложении, но когда я указываю свой путь, я получаю ошибку.

my putput:

 xls
<HttpResponse status_code=200, "application/vnd.ms-excel"> responsefffffffffff
<_io.TextIOWrapper name='drftesting1.xls' mode='r' encoding='UTF-8'> fileee

2-й метод

   def generate_file_xls(self):
    try:
        myfile = open('test.xlsx', 'wb')
        wr = csv.writer(myfile)
        wr.writerow(('Designation','Role','Department','Staff 
     Name','Mobile','Email','Address','Erp Code'))
        wr.writerow(('Call center agent','teacher', 'Marketing', 
    'abctest', '1231231234', 'test@gmail.com', 'ewerq,sdfa', 
    '5677ERP'))
        wr.writerow(('Digital executive','planner', 'maths', 
 'abctest2', '1231231234', 'test2@gmail.com', 'dfsfsdf,wefwef', 
 '90765ERP'))
    finally:
        myfile.close()

    return myfile

Когда я использовал 2-й метод, лист Excel был создан и использовался для правильного ввода, но я хочу, чтобы он был в рабочей книге, тогда только мойкод будет работать
