Excel Formatting & Capabilities Question

(NEWBIE)

I have a mailing list I put together of the last several months; over 2000+ Name and Addresses. How do I configure my list in a fast/quick/easy way in to the right format using Excel or some other type of computer software? I need for this same list to be corrected/modified by adding the necessary commas within the right areas for importing into a Mailing Software. Would I have to manually add the commas (comma delimited) in the right areas one-by-one using Excel or is there a software out their - that will do that for me fast and automatically (so-to-speak)?

EXAMPLE OF THE CORRECT FORMAT I AM LOOKING FOR: ABC Company, 1234 Jones Blvd, Las Vegas, Nevada, 89119, abc@yet.net

REQUIREMENT: I need six fields/grids: Company, Street/Mail Address, City, State, Zip-code and Email Address – ALL separated properly with a comma in the right areas.

Here is a sample of my list (Names & Addresses Have Been Modified For Privacy Issues):
