A while back I had a client who needed to do a short run geocoding job, just a couple hundred address from an excel sheet. I could not find a free short run geocoding service, so I wrote a geocoder module. It utilizes google’s maps api, and accepts input as a single line or a csv file. Feel free to register an account to test out the bulk geocoder, it is currently limited to 200 addresses at a time. The single address geocoder will be available for anonymous use until someone starts abusing it. :)
