I am trying to create a membership/subscription website where I can allow a monthly fee for members to access an Excel file that I have embedded into one of my pages. I have successfully uploaded the file to OneDrive, embedded the file onto a webpage, and added a member's login to my site. The problem I'm running into is that I want each user to have their own file but do not want to have to upload one specifically for them. I just want them to be able to access the file and have the relevant tables empty when they open it each time. I do not want them to collaborate or to see each other's data as it is unique and sensitive to each of them individually. But I want them all to access the same file and keep it updated. I don't want them to be able to download the Excel file either. Right now, they purchase a digital download of the Excel file from my site but I have to send out updates to the file as needed.
