Via vba, you would use Docmd.actransferspreadsheet Acimport,, "your file name",
"C:\whatever" , true, "sheet1!A4:d10"
The true is if you have column headers you want to import with the document.
Easiest is to use the Access menu; select File... Get External Data... Import;
select .xls on the "files of type" dropdown, and then your workbook file.
TransferSpreadsheet does the same thing in VBA code and would be better for a
recurring task.
