I've used it directly to Excel.
I think the format is OK - but what I'd rather see is just the raw data so that I can cut and paste into and estimate form. Depending on what material I spec or where it gets ordered depending on if I order even lengths, how I control the round up (did I do joinery or is it for an esimate), etc. etc.
So the list is good - but I don't think it needs to do everything.
Also, exporting the raw data would be useful as someone who wants to use SketchUp for estimating panels / conventional enclosures.
