title: Splitting names in one cell and adding commas between to new cell
body: <p>I am an excel novice, and I really have no idea what I am doing...</p>
  
  <p>But I have a list of 1500 names in Column A.  I'd like to have a function for column C that takes each work in Column A and adds a comma between them, and displays that in Column C...</p>
  
  <p>I have the names in Column A, and want to create a string of tags that will be in Column C.  </p>
  
  <p>Also, if it's possible to get the first letter of the last word in the string, then Column C will be made up of First Name, Last Name, First Letter of Last Name.</p>
  
  <p>Any help would be great!</p>
