I'm pretty new to using excel and am having a bit of a problem with this. I have two spreadsheets full of products one of new products and the other of old products. I want to filter out the old ones that are discontinued but keep the ones that are still there. The old list has data I want to preserve for the new listings that would be duplicates from the old ones. I want to delete the new listings that already exist in the old list. I'm not sure exactly how to do it. I tried to delete dups based on product id or name but I'm afraid it's deleting entries I want to keep. Both lists contain over 5000 products each. I need to compare two lists and filter out the old products then work on removing the dupes. I hope this explains what I'm trying to do.
