Is this related to Enterprise Guide or are you using PROC EXPORT? And from your message, it wasn't clear whether you don't have Excel or you don't have SAS/ACCESS to PC File Formats.
If using Enterprise Guide, you can do a "Send To Excel" (assuming that you have Microsoft Excel), and EG will automate Excel and populate a sheet with the formatted values. This does NOT require SAS/ACCESS to PC File Formats.
You can also Export data to an xls file from EG. That also does not require the SAS/ACCESS product.
