I am not sure whether there are other dashboard apps that specifically have the option to display an Excel file. One of the most extensive dashboards app (for creating a web page based dashboard) is Dashboard Studio. A major version was also released today (in test still):
- App link: Dashboard Studio
- Forum topic link: [APP][Pro] Dashboard Studio - A completely free-form dashboard designer
You might want to ask in the linked topic whether what you want is possible in that solution.
