  <p>I have some excel xls file . I want to parse it by using <code>xlsx package</code> (<a href="https://www.npmjs.com/package/xlsx" rel="nofollow noreferrer">https://www.npmjs.com/package/xlsx</a>) .. I read a file by <code>multer</code>  and get some <code>req.file.buffer</code> response and try to parse this response in this way . </p>
  
  <pre><code>const xlsx = require('xlsx');
  let x = xlsx.read(req.file.buffer, {type:"buffer"});
  </code></pre>
  
  <p>when u will make request like <code>console.log(x.Strings);</code> u will get smth like this :</p>
  
  <pre><code>[ { t: 'first_name', raw: '&lt;t&gt;first_name&lt;/t&gt;', r: 'first_name' },
    { t: 'middle_name', raw: '&lt;t&gt;middle_name&lt;/t&gt;', r: 'middle_name' },
    { t: 'last_name', raw: '&lt;t&gt;last_name&lt;/t&gt;', r: 'last_name' },
    { t: 'phone_number_first',
      raw: '&lt;t&gt;phone_number_first&lt;/t&gt;',
      r: 'phone_number_first' },
    { t: 'phone_number_second',
      raw: '&lt;t&gt;phone_number_second&lt;/t&gt;',
      r: 'phone_number_second' },
    { t: 'email', raw: '&lt;t&gt;email&lt;/t&gt;', r: 'email' },
    { t: 'address1', raw: '&lt;t&gt;address1&lt;/t&gt;', r: 'address1' },
    { t: 'address2', raw: '&lt;t&gt;address2&lt;/t&gt;', r: 'address2' },
    { t: 'zipcode', raw: '&lt;t&gt;zipcode&lt;/t&gt;', r: 'zipcode' },
    { t: 'city', raw: '&lt;t&gt;city&lt;/t&gt;', r: 'city' },
    { t: 'state', raw: '&lt;t&gt;state&lt;/t&gt;', r: 'state' },
    { t: 'fds', raw: '&lt;t&gt;fds&lt;/t&gt;', r: 'fds' },
    { t: 'fsd', raw: '&lt;t&gt;fsd&lt;/t&gt;', r: 'fsd' },
    { t: '[19674913171]',
      raw: '&lt;t&gt;[19674913171]&lt;/t&gt;',
      r: '[19674913171]' },
    { t: 'fdssd@gmail.com',
      raw: '&lt;t&gt;fdssd@gmail.com&lt;/t&gt;',
      r: 'fdssd@gmail.com' },
    { t: 'fdsfs', raw: '&lt;t&gt;fdsfs&lt;/t&gt;', r: 'fdsfs' },

How to configure it in the way when I don't need to add some characters and get response :</p>
  
  <pre><code>{ t: '19674913171',
