I have a list of product in a CSV file. I want to download product spec of those products from icecat. Software should give facility to put one product at a time or list of product at a time and it should download spec from icecat like sku, manufacturer part number, icecat code, picture, category tyep, category name, description, lenght, size etc. I mean all the available data into a csv file with column headings. Please note that different items will have different column headings.
