Add item descriptions off eBay listings onto spreadsheet

Hi, I would like an easy job completed.... To add my eBay item descriptions onto a spreadsheet ready for Amazon upload To check back after every 50 entries for me to check they are all correct The quicker the better There are 686 in total I will email you a spreadsheet with all the other data already on there, ie price, image url ect. None of these to be changed, only item description added. Thanks
