Again, those fields have no meaning unless they are tied to a task. You could use the Visual Report, convert the visual report to formulas (breaking the link with the OLAP cube) and then perform any work in Excel that you would like.

An alternative is the export the data through VBA. But I am not the person to help you with that, sorry. If you have skills in VBA, search for excerpts from Rod Gill's book on Project VBA on the MSDN site.

As far as being sure there should be a better solution - if I knew of one I'd share it. Project is NOT Excel and the fields and options are set by the database structure.
