How to import an XP .csv file to 8.1

I have been using XP system, outlook express on a desktop computer. As XP is "out", I am now using a laptop Asus Q501LA-BB15T03 and want to use my old outlook express email address file on the new computer. I made up a .csv file to transfer the information and don't know how to import it into the new computer which is set up for Windows Live Mail 2012.

Please help.

Thanks, Jay
