To throw in my two cents here, I’m having some success with something called Appsheet. (www.appsheet.com)
It’s literally a software that reads your excel file, and creates an web interface to update it, even as a mobile app.
But let me warn you, this software can get pretty in depth with different excel-like functions and expressions. However, I’ve successfully used it with a simple XP, sync’d the excel sheet through OneDrive to my Intuiface player, and used MirrorFolders to copy the excel file into Intuiface backend. I was able to update a directory board from the cloud account in a matter of seconds. You can also permit only certain users to access the app and make updates.
Later this year when I get my process smoothed out, I plan on releasing a nice description in this community so others can follow. But at least you can take an early look. Good luck!
