I'm working for a big nonprofit that uses convio for web donations and raisersedge for data management but the two don't link up so I have to downland the csv from convio clean it up in excel and import into raisersedge. I run a large macro and do some cleaning manually too but would love to offer them a better solution. ..or I want to suggest better software because raisersedge is atrocious
