Download/Upload Excel workbook created with openpyxl using dialog box

Question

I'm using Django and Openpyxl to create an app that can write an Excel workbook using data from the app and then save the file locally.

When I used:

wb = Workbook()
wb.save('test.xlsx')

The file was saved in my Django project's root folder.

How can I have the file download to the browser's download folder as opposed to saving directly in the root directory of the app on its server?

Thanks.

openpyxl provides a function to save a file to a StringIO object:

from openpyxl.writer.excel import save_virtual_workbook
stream = save_virtual_workbook(wb)

However, for larger files it might be preferable to save to somewhere in the file system and let the http server handle the download.
