Wholesale catalog sourcing help

Hello, Ive been selling on Amazon for over a year now. I’m looking to make the move to wholesale. I’ve received catalogs from a few distributors but I’m finding it hard to find a profitable product because I’m manually checking each item to see if it’s profitable. There is hundreds of products per catalog. Can anyone recommend a software where I can input all the UPC’s or asins from the catalogs and have it search for me if its profitable depending on criteria I have imputed? Thanks in advance
