title: Reading Excel through exceljs module
body: <p>I am reading excel by using <code>exceljs</code> module. When my excel file in same folder. It works fine.</p>
  
  <pre><code>var workbook = new Excel.Workbook(); 
  workbook.xlsx.readFile('Data.xls')
      .then(function() {
          var worksheet = workbook.getWorksheet(sheet);
          worksheet.eachRow({ includeEmpty: true }, function(row, rowNumber) {
            console.log("Row " + rowNumber + " = " + JSON.stringify(row.values));
          });
      });
  </code></pre>
  
  <p>But When my excel file in some other folder and I try to give fileName with path, It throws console error, that file not found.
  my file structure is like below:</p>
  
  <p>TestFolder</p>
  
  <p>|------nodemodules/</p>
  
  <p>|------example/js/e2e/fileServer.js</p>
  
  <p>|------data/Data.xls</p>
  
  <p>My Question is How to provide relative path of excel file in <code>readFile()</code>. I want to provide path for <code>Data.xls</code> in <code>fileServer.js</code> file.</p>
