I have three lists that need to be combined into a single spread sheet that is can be used in a phplist program for sending emails. Two of them are in cvs format. One of these - with about 1600 addresses -- is from a google list and the other - with about 800 addresses - is already functioning on a phplist. The third list is about 50 addresses that are just in a regular doc or odt file. In addition to the email addresses there is a smattering of other info on the lists -- but the main thing is the emails.
