Hi,
Here is what I did for demo purposes.
Business need: users want to upload excel files which include detailed calculation of a number.
Example: users are inputting aje or rje for consolidation and they want to add the detail of that journal as excel file.
I am allowing users to upload excel file and then they can download it when needed.
Technically, ux is already storing file location to a cell, and I am converting that file name into an html link so that it is downloaded when the user clicks on the link.
