Cant get my head round delimited files

Question

hey guys i have been trying to sort this out for ages but i just cant get it to display correctly just wondering if any one could help
Create a comma delimited file for example:
     Smith, Jon
     Bloggs, Fred
     Jones, Anne
Then simply read each item of data and display it to look like this:
     Jon Smith
     Fred Bloggs
     Anne Jones
