my code actually worked. I thought it was going to save the excel file to
'C:\excel' folder so i was looking for the file in the folder but i
couldn't find the excel file. The excel file was actually exported to my
django project folder instead.

How to i allow the end user to be able to download the file to their
desktop instead of exporting it to the server itself
