title: Reading from CSV and filtering columns
body: <p>I have a CSV file.</p>
  
  <p>There are a fixed number of columns and an unknown number of rows. </p>
  
  <p>The information I need is always in the same 2 columns but not in the same row.</p>
  
  <p>When column 6 has a 17 character value I also need to get the data from column 0. </p>
  
  <p>This is an example row from the CSV file:</p>
  
  <pre><code>E4:DD:EF:1C:00:4F, 2012-10-08 11:29:04, 2012-10-08 11:29:56, -75, 9, 18:35:2C:18:16:ED,
  </code></pre>
