title: VLOOKUP returns #N/A in PHPSpreadsheet
body: <p>I am trying to work with a calculator implemented in excel file with phpspreadsheet. Working with multiple sheets. First sheet has calculator itself.</p>
  
  <p>Am I putting values right in way in it?</p>
  
  <pre><code>$spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load('calc.xlsx');
  $worksheet = $spreadsheet-&gt;setActiveSheetIndex(0);
  $worksheet-&gt;setCellValue('D8', 210000);
  $worksheet-&gt;setCellValue('D9', 160000);
  $worksheet-&gt;setCellValue('D10', '5%');
  $worksheet-&gt;setCellValue('D11', 30);
  $worksheet-&gt;setCellValue('D12', -1073);
  $worksheet-&gt;setCellValue('D15', 50000);
  $worksheet-&gt;setCellValue('D16', '7%');
  $worksheet-&gt;setCellValue('D19', 5000);
  $worksheet-&gt;setCellValue('D20', 5000);
  $worksheet-&gt;setCellValue('D21', 4500);
  $worksheet-&gt;setCellValue('D24', '12/7/2018');
  </code></pre>
  
  <p>Because below code outputs #N/A</p>
  
  <pre><code>$worksheet-&gt;setCellValue('I8', '=VLOOKUP("L",Daily!A:N,3,FALSE)');
  echo $worksheet-&gt;getCell('I8')-&gt;getFormattedValue();
  </code></pre>
  
  <p>Trying to do this in a wrdpress plugin.</p>
