title: JAVASCRIPT reading value from excel sheet displas a diffrent value
body: <p>currently, I am working on a function that is needed to import all the excel data into json objects on a website, therefore I have used the <code>XLSX.utils.sheet_to_json</code> utility on JS which brings me all the data to JSON on the web page. but few data are invalid which are not the same as on the excel sheet specifically date formats.</p>
  <p>on the read method what I was following is below</p>
  <pre><code>  var workbook = XLSX.read(data, {
          type: &quot;binary&quot;, 
    });
  </code></pre>
  <p>do I need to add anything else to get the date data correctly?</p>
