Importing excel .xls or comma delimited file into motorola droid x android 2.2 phone book

So I had a 5 yr old blackberry, was able to use the blackberry software to output my phone book (name,addy,ph#, all kinds of data) to a comma delimited txt file, which i then imported into an .xls excel spreadsheet

is there a way to use either of those files to populate my phone book on my new phone (droid x, android 2.2) instead of typing up hundreds of new entries?
