WonderLister – the premier eBay listing management software provides many time and money saving features. If you sell on more than one eCommerce channel, WonderLister lets you easily import your data files to other eCommerce websites such as Amazon and Etsy. WonderLister lets you define one or more export layouts, called mappers. For each mapper, you can select the columns you’d like exported, the order in which these columns should be exported and even assign a new name for each column, if necessary.
