Yes, importing as tab or comma delimited will work very nicely. mostly just like PB. Note that appeon is limited in importing comma delimited to full file only . while tab delimited can be done either as full file or a row/line at a time.
the other option is to use excel directly via the excel com objects to import/export to excel. this means the client would require excel to be installed:
ioo_excel = CREATE OleObject
ll_rval = ioo_excel.ConnectToNewObject("Excel.Application")
....
