FM to pass data into internal table

Hi Experts,

I am using FM  'ALSM_EXCEL_TO_INTERNAL_TABLE'  to pass the excel sheet data into internal table. But this FM is accepting only .xlsx format excel sheet.

i tried      KCD_EXCEL_OLE_TO_INT_CONVERT,

               TEXT_CONVERT_XLS_TO_SAP these fm bit getting dump

Do we have any FM available , which is accepting .xls/ .xlsx both the format as input excel sheet.

This is a basic question, need your help here.

Regards,

A. N.
