Are you referring to the Apple Address Book, the Office Address Book, some
other Address Book?
If it happens to be the Apple Address Book it will not import from an Excel
File. You need to save the Excel file as a Text file then use the Address
Book's File> Import facility. That Address Book, however, is an Apple
product & it's unlikely that anyone here is familiar with the process from
that end. You might do better to ask in the appropriate Apple Discussions
forum. Information on creating the Text file can be found in Excel Help.
