You will still have to go to each profile and clean it up. Gedcom uploads usually leave a mess. I opted to input mine by hand which turned out well. After a few generations I connected to the tree so I actually didn't have to input all my ancestors, as a lot were already on Wikitree. It also gave me an opportunity to review the information I had as I added them, to make sure I had good sources, and things were correct (as far as I knew).
Hope your Gedcom upload goes well and you don't have too much to clean up.
