title: Convert a string containing days, hours and minutes into hh:mm:ss
body: <p>I have 400 records to process and they are in the following formats (string):</p>
  
  <pre><code>3h
  24h20min
  3h
  2d
  26min
  1h12min
  17h35min
  6h12min
  30s
  </code></pre>
  
  <p>How do I make a formula that would automatically detect the <code>d</code>, <code>h</code>, <code>min</code> and <code>s</code> and convert into the right <code>hh:mm:ss</code> with hh being eventually higher than 24?</p>
