title: Looping a formula through numerous spreadsheets
body: <p>I have the following three Excel (2010) formulas which perform exactly what I want them to:</p>
  
  <pre><code>=IF([NoData]Sheet1!C4=ISBLANK(TRUE)," ",[NoData]Sheet1!A4)
  =IF([NoData]Sheet1!C4=ISBLANK(TRUE)," ",[NoData]Sheet1!C4)
  =IF([NoData]Sheet1!C4=ISBLANK(TRUE)," ",[NoData]Sheet1!K4)
  </code></pre>
  
  <p>I want these three formulas to run through data in several worksheets contained within a given workbook. The cells that they will operate on will remain the same for each worksheet.  </p>
  
  <p>How can I run these three formulas through 11 or 12 different worksheets within the given workbook? </p>
