I need someone who can take a large commission junction datafeed file and subdivide it accurately into smaller categories. for example you will take a large affilate feed file from best buy and sort it into smaller categories : appliances : electronics : etc. if you have the skills or tools to automate it let me know so the idea is you take a large datafeed excel or text file : say bestbuy ; you then subdivide this into smaller categories such as electronics, stereos, headphones etc. or a shoestore datafeed file ; you then subdividide this into shoes, bags, basketball shoes etc. somone who can write excel marcors or scripts is needed. With scripts this is a very easy task.
