this got me in the right direction. The product in the sdk was something by innovasys. this lead me to documentX which does this. It's pretty good, but about 450 bucks.
this lead me to try other things first...
One thought for the LLBL IDE is to have the grids export to excel. This would probably be a quick easy solution for you. I'm not sure about Janus grid, but with infragistics it was as easy as droping an export control on the form and pointing it at the grid.
Would your pluging model allow for me doing this? I can get to everything in the llbl file right? I might look into this if I have time.
