title: Compare two columns in excel with different lengths
body: <p>I have two columns in Excel, with different length.  They contain links to SharePoint sites.</p>
  
  <p>I need to make a comparison, so that in column C, I would like to get all the links that exist in column A and not B.</p>
  
  <p>In column D I would like to get all the links that exist in column B and not A.</p>
  
  <p>To clarify, in the C and D column I want the link values, and not any true, false or 0 or 1.</p>
  
  <p>As it's links I don't see how any test data would help to be posted here but in case you need it, leave a comment and I'll put something together as I cant post the company links here.</p>
