Might be worth doing some data reduction if the data are all over the place as you describe. Delete (or hide) rows/columns if you can easily identify them. I might be inclined to export as csv and use something like awk - say " if column2 and column3 and column28 are all zero delete the entire record". Then re-import the reduced file.

Good idea, but it would be nice to visualize it in some way. I wonder if awk could generate an xpm image. Hmm......

You have me thinking of something penguiny.
