This is a common type of data format which programs from Mainframes, to Microsoft Excel can output.
It is also called the "Comma Delimited" format, or just "Delimited" which means to separate by.
CSV files separate the fields by columns with a comma, and the records in to rows with a carriage return.
Many All-USA address CDs come in this format. You can output the area codes or states you wish, then process them with the CallNot Software.
Here is an example where we would process the 6th field for Phone. (Actual names and numbers changed for privacy)
