"Cannot interpret data in file" error while using GUI_UPLOAD for .xls file

Question

Hi,
     I have made a program using FM GUI_UPLOAD to upload an .xls file to an internal table. But upon executing ,it gives error "Cannot Interpret data in file". I have seen in other posts people talking about GUI_UPLOAD FM to upload data from excel directly into internal table. Kindly help.
Here is my code. I had tried using different combination for HAS_FIELD_SEPARATOR but still its not working.
In my emp1.xls file , the data in each column is present in the same order as in the internal table. Although the first column in my internal table is NUMC. I dont know if that is causing the problem.
REPORT  ZUPLOAD_1.
data: itab TYPE TABLE OF zempl_master WITH HEADER LINE.
CALL FUNCTION 'GUI_UPLOAD'
  EXPORTING
    FILENAME                      = 'C:\empl1.xls'
    FILETYPE                      = 'ASC'

hi amber22 you need to use the below fm to upload an xls file

      I_END_COL   = 6
      I_END_ROW   = 100
    TABLES
      INTERN      = xl_itab.
