This is the limitation of SAS on 32bit system, if you run your SAS on 64bit Windows you can try
%let import_path=yourExcelFile.xlsx;
Proc IMPORT OUT= WORK.ImportedExcel
DATAFILE= "&import_path"
DBMS=XLSX REPLACE;
run;
If you only can run your SAS on 32bit Windows, you can try to export the Excel sheet to a TXT file with Tab delimitation, then import from the TXT.
Good luck!
