This is a suggestion for Esri Maps for Office (Excel) to have the capability to view (or even edit) attribute information of a map or feature service.
For example, if I seach for a map (or feature) service and add it to my Excel map, I'd like to be able to (from the layer's context menu) add the service's entire attribute table (or subset of attributes) to a specified cell range inside my Excel workbook.
This would be very useful as a read-only view of the data, and would also be an interesting way of editing (feature service) attribute data as well. If you modified the attribute information in the spreadsheet their could be a way for users (with sufficient permissions) to push those updates back to the feature service.
