title: How can I merge CSV rows that have the same value in the first cell?

  <p>As you can see, there are duplicates in the first column, but if I were to combine the duplicate rows, no data would get overridden in the other columns. Is there any way I can combine the rows with duplicate values in the first column?</p>
  
  <p>For example, turn "1,A,A,," and "1,,,T,T" into "1,A,A,T,T".</p>
