title: excel default value for IF
body: <p>Is it possible to add a "default value" for an if?</p>
  
  <p>Let's give an example:</p>
  
  <p><code>if (formula="", "", formula)</code> or more specifically:</p>
  
  <p><code>if (trim(INDIRECT(ADDRESS($G$2+1+$K6,$F6+L$5,4,TRUE,$F$2))) = "", "", INDIRECT(ADDRESS($G$2+1+$K6,$F6+L$5,4,TRUE,$F$2)))</code></p>
