title: Can't find data referred to in an Excel formula
body: <p>I've inherited a spreadsheet with no instructions.</p>
  
  <p>There is a formula in one of the cells:</p>
  
  <pre><code>=IFERROR(ROUND((SUM('RawData'!C:C)/K21)*24*60*60,0),0)
  </code></pre>
  
  <p>There are no hidden tabs - so I'm guessing 'RawData' is a named reference of some sort.</p>
  
  <p>Is there any way for me to find out where the data is referred to in 'RawData'?</p>
  
  <p>Thanks for any help, Mark</p>
