Clean Up CSV from data feeds

I have merchant csv and they contain product information along with other information. I will need the csv to be a 5 column csv from the original 15+ column. They also have to remove some items from the data and replace some items. It would be a stand alone application. I have a script as a base for you to use and give you an idea of what I need. I would prefer it be a desktop application. If there is other information need please contact. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
