That is quite possible using a letter mailmerge in Word.

To use this, your Excel data would need to be organised in columns, with a column for the supplier names and at least one column for each separate address line. The first row in Excel would be a header row and each subsequent row would have the supplier details. Thus, for the header row, you might have:
Supplier, Address1,Address2,Locality,State,Zip
It doesn't matter if some suppliers only have one address line - the blank ones can be suppressed in the mailmerge.

In Word, you'd write the letter as if it were going to just one supplier. having done that, you'd use Word's mailing tools to create the mailmerge. See:
