title: Intersection of Excel Columns in Respect to a Third Column
body: <p>Suppose I have 3 columns in my excel file that look like this:</p>
  
  <p>Column A has the values {A,B,C,...,Z} (each value is a cell down the row)</p>
  
  <p>Column B has the values {www.link.com/A/browse.html,...,www.link.com/Z/browse.html}</p>
  
  <p>Column C has the values {A,1,B,2,D,5,78,...Z,54}</p>
  
  <p>That is, column A doesn't contain C and neither does C contain A, but they do have common values, and column B has the values of A within a link.</p>
  
  <p>I need to get all the rows of B so that their "name", A,B,..,Z, in my example, appears in column C and of course in A (the intersection of both columns, but yielding the link from column B).</p>
  
  <p>Thanks for the help!</p>
