Issue when importing spread sheet into matlab

Hello,

I'm trying to import an string spread sheet into matlab by using the importdata button. However, it does not allow to do so, I got the following message:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.mathworks.mlwidgets.importtool.WorksheetTableModel.getDefaultColumnTargetTypes(WorksheetTableModel.java:166) at com.mathworks.mlwidgets.importtool.WorksheetTable.setTargetType(WorksheetTable.java:714) at com.mathworks.mlwidgets.importtool.SpreadsheetTabbedPane$TabContentPanel.build(SpreadsheetTabbedPane.java:549) at com.mathworks.mlwidgets.importtool.SpreadsheetTabbedPane$TabContentPanel.access$600(SpreadsheetTabbedPane.java:421) at com.mathworks.mlwidgets.importtool.SpreadsheetTabbedPane$TabContentPanel$1.worksheetCachedDataChanged(SpreadsheetTabbedPane.java:531) at com.mathworks.mlwidgets.importtool.ImportTable.fireWorksheetCachedDataListeners(ImportTable.java:1016) at com.mathworks.mlwidgets.importtool.WorksheetTable.worksheetCachedDataChanged(WorksheetTable.java:168) at com.mathworks.mlwidgets.importtool.AbstractFileTableModel.fireWorksheetCachedDataListeners(AbstractFileTableModel.java:621) at com.mathworks.mlwidgets.importtool.AbstractFileTableModel.matlabCallback(AbstractFileTableModel.java:772) at com.mathworks.mlwidgets.importtool.WorksheetTableModel$4$2.run(WorksheetTableModel.java:550) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:251) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:721) at java.awt.EventQueue.access$200(EventQueue.java:103) at java.awt.EventQueue$3.run(EventQueue.java:682) at java.awt.EventQueue$3.run(EventQueue.java:680) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:691) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:161) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:150) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:146) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:138) at java.awt.EventDispatchThread.run(EventDispatchThread.java:91)

Does anyone know what should I do.

Thanks.

Will the tool do anything or just the given spreadsheet?
