I was told Excel can do this, but I'm not very familiar with the program.. Example:

First Names: John, Ryan, Michael
Last Names: Smith, Williams, Jones

I need to create a final list that will look like

John.Smith
John.Williams
John.Jones
Ryan.Smith
Ryan.Williams
Ryan.Jones
Michael.Smith

etc

Any help in the right direction would be much appreciatd. I've googled but have only used Excel for very simple tasks and formulas. Thank you so much.
