title: How to use excel files with Nest JS
body: <p>I am trying to creat a rest api which uses a third part api to get some status. I'll get the url from a excel file, for this specific case it needs to be a excel file, use them in my service to obtain the data from the third part api and save this response in the same excel file. I am already able to get the data from the third part api, but I'm failing to manage the excel through nest js. I tried to use exceljs library but it didn't work as I intended. I would like to have the return(assume it is inside a function) to be the cell value in this excel file. Could someone give me some hint in how to handle this file use inside nest js?</p>
  <pre><code>let Excel = require('exceljs');
      let workBook = new Excel.Workbook();
      workBook.xlsx.readFile('./ExcelFile/Archive.xlsx').then(function()
      {
          let sheet = workBook.getWorkSheet(&quot;Sheet1&quot;);
          let cellValue = sheet.getRow(2).getCell(1).value;
      });
      return cellValue;
  </code></pre>
