title: How to read xlsx file with ExcelJS?
body: <p>How does the code should look like to get cell A1 value from the file "C:\1.xlsx"? I tried numbers of examples but still didn't managed to get it work.</p>
  
  <pre><code>var Excel = require('exceljs');
  
  var workbook = new Excel.Workbook();
  
  workbook.xlsx.readFile("C:\1.xlsx")
      .then(function() {
          var worksheet = workbook.getWorksheet('Sheet1');
          var cell = worksheet.getCell('A1').value;
          console.log(cell);
      });
  </code></pre>
