Copy and Paste Data from Manufacturer\'s website onto another - repost 3

There are currently 45 products on a Shopify ecommerce store that is currently under construction. \r\n\r\nWhat I would like is for each of these products to have a product description, which they currently do not have. As an example, nine have already been completed leaving only 36 remaining.\r\n\r\nShopify has a bulk upload ability from a .csv file where HTML can be entered into a cell. This partially (at the moment) completed file will be provided.\r\n\r\nTo include the manufacturer\'s wording, please copy and paste directly from the source code of the website, while removing any specific CSS from their website, to accurately capture all bullet points, tables and their formatting.
