I'm looking for a formatted list, ideally in csv, xls or txt format, of products listed in Amazon or Ebay. For example, from the following departments from Amazon: Sports & Outdoors ? Other Sports ? Martial Arts ? Weapons ? Martial Art Knives What I'd want from here is "Martial Art Knives". So it would be a huge list with product names like "Kitchen Knives", "Sharpening Stones", "Microwave Stand", etc, not the specific product model and brand but what the generic product is called. Amazon and Ebay are just an example, I'd need like a huge dictionary or encyclopedia of product names. Hope my request made sense.
