Fix Excel Address List

I have an Excel address book, about 900 lines, and I would like to fix it so that it has a column for Name, Last Name, State, City, Zip code, phone, and cell phone. Yes, I have the information in three columns now. I want it in as many columns so that I can import to Access. so: Fist Name, Last Name, Street Address, PO box (other info such as apt #), State, Zip, Phone, Cell Phone, also some people have an alternate address in another country. Can u do this?
