The only other currently available method for export of the grid would be to just highlight the entire grid and use ctrl-c to copy it. You could then paste it into Excel and do whatever you want with it from there.
Additionally, you could save the grid to a .bps file using File > Save. The .bps file is pure xml, which means that it can be loaded into a spreadsheet app like Excel, or a database.
We are considering more options for a future version, including database interaction of some kind. However, at the moment this is not available in the currently published build, and I’m not sure what the timeline is for it to become available or if it will definitely become available.
