Import Keywords to tag images using excel file

Hello all. I have recently purchased the Javascript for Adobe Bridge reference book as well as the Javascript Bible reference book. I'm not asking for a fully fleshed out code but maybe some direction on where to begin. If my images are all contained in a folder but the naming conventions are not based on any sequential hierarchal system but rather varying sets of three digit numerical codes, is it possible to whip together a javascript file that takes an xls spreadsheet with specific keyword columns and rows and parses through, embedding certain rows of information onto corresponding images containing three digit code sets, if that makes any sense? Thanks and look forward to further discourse pertaining to this topic.
