I have multiple excel spreadsheets that query a database for data using a SQL query I wrote, that then displays excel based reports/dashboards. You can also grab data from a bunch of other sources - sharepoint, etc.

Then you can just update from excel and everything is in the right format for non programming people to use.

The thing about excel is that for large orgs its probably on every computer and almost everyone sort of knows how to use the basics of it. that gives it value.

The real value would be if there was some way I could get excel on a random machine without any privileges to refresh the data itself on a schedule.
