title: How to save CSE Excel formula in plain CSV format?
body: <p>I would like to form CSV excel file in my program. Some cells contains CSE (Ctrl+Shift+Enter) formulas (array formulas).</p>
  
  <p>This does not work:</p>
  
  <pre><code>=SUM(IF(COUNTIF(B4:B1000;B4:B1000)=0; ""; 1/COUNTIF(B4:B1000;B4:B1000)))
  </code></pre>
  
  <p>This does not work too:</p>
  
  <pre><code>{=SUM(IF(COUNTIF(B4:B1000;B4:B1000)=0; ""; 1/COUNTIF(B4:B1000;B4:B1000)))}
  </code></pre>
  
  <p>This formula makes distinct count on cells array...</p>
