First, it would be helpful if there was a way to apply a format for an entire column (except for, obviously, header and footer rows). This would prevent us from having to write a script that loops over every row to format every 3rd column (for example) to a specific format.

In addition, it would be nice to be able to use Kendo formats for columns and have that automatically translated into Excel formats. In my case, I have to write a translation layer that, in my opinion, would be much simpler if it was incorporated into the back end. If this could even auto-format to match the format used in the grid display on the page, it would be even better.
