GUI_UPLOAD to read data from an Excel File

Question

Hi Folks,
I'm using FM GUI_UPLOAD to read data from an Excel File. But all I see in the table returned is 1 row with garbage values (special chacaters). Excel Workbook has proper data in the sheet, but its not getting uploaded properly. Sy-subrc is 0.
What could be the reason?
Thanks
