I am generating an excel spreadsheet in python using xlsxwriter in the backend of a webapp, which is then stored on the server. The link to that is then sent to the frontend and downloaded in the browser. Similar to this: How to download excel file that is generated by xlsxwriter in browser with using fastapi?

I was wondering if there is not an easier way using BytesIO to download temporarily instead of processing and storing the file locally and taking up space.
import xlsxwriter
from io import BytesIO

import xlsxwriter
from io import BytesIO

Thank you so much for pointing me in the right direction.
