Using the clipboard to export/import spark data?

I'd like to look into using the clipboard to import and export spark data, as a way of doing the level modeling in a different program, one with better tools.

I (finally!) found a program that will let me look at the raw clipboard data (InsideClipboard) and I can't make heads or tails of the data

I would love some information about the format of how data is stored in the clipboard. Does anybody have any insight on this?
