I am unable to actually import my inventory via excel, even with the template given and downloaded and also added in I still had problem importing it with error.
It might due to your excel file size is too big. The easier way is to break it into several files in smaller size (about 500-1000 recirds per file). If you still hit error in smaller file, it might due to your Office's driver is not up to date, please download the file from http://www.xincube.com/PatchDownload/AccessDatabaseEngine.exe , click and install the component to your computer. It is a component from Microsoft, for more information please visit http://www.microsoft.com/download/en/confirmation.aspx?id=23734.
If after installing the component update you still face the same error, please contact Xin Cube Support at http://support.xincube.com by providing your excel files with data for further investigation.
