When people work in Excel they create tables which layout maybe understandable for humans but cannot be used to export data or generate pivot tables due to hierarchy for instance. Alternative organization of data storage is flatten table. With XLTools Unpivot Table app a flatten table is created by a user 2D table automatically just by one mouse click. Of course a user can manually copy and paste data to generate a flatten table but there is a high possibility that he will make a mistake, lose data or miss something and it will take a lot of time to get the result. Thanks to XLTools Unpivot Table the converting process is performed automatically and immediately!
