@deanho22 what do you mean by live? there are no modules that provide live data updates as you click, there is always some polling rate
there is currently no module that processes
excel sheets directly
you can export it as csv, convert the csv to json, and then there are modules that can use the json
see the 3rd party module list linked in the top menu above.
think about the data in the sheet, to have a readable view from 10-20 feet away takes a decent sized font, which means not much data can be displayed. add on clock and weather may take a pretty big display.
or you have to cycle what is in view with one of the modules that makes logical pages
definitely doable, you will need to learn a lot
