Create Google Earth kml files from 3 excel files

I"d like to create 3 Google Earth kml files from 3 excel files. they have about 6000 addresses, 4000 addresses and 1400 addresses in each file, respectively. the deliverable will be three kml files. Columns in the excel files are name, address, city, state, zip. this would be easy for anyone with the upper level google earth program (can import and save). google plus has a limit of 100 addresses. i'll be spot checking the files for accuracy. ## Deliverables 3 kml files that can be opened in google earth ## Platform mac osx (but the kml files are platform independent so i don't think it matters)
