title: Protractor excel4node doesn't work
body: <p>I'm trying to save some data into my excel:</p>
  
  <pre><code>var xl = require('excel4node');
  var wb = new xl.Workbook();
  var ws = wb.addWorksheet('abc1');
  ws.cell(1,1).string('abc2');
  ws.cell(1,2).string('abc3');
  ws.cell(1,3).string('abc4');
  ws.cell(1,4).string('abc5');
  </code></pre>
  
  <p>It works fine but when i am trying to:</p>
  
  <pre><code>var a = element(by.className('token')).getText();
  ws.cell(2,8).string(a);
  </code></pre>
  
  <p>I get an error:</p>
  
  <blockquote>
    <p>Failed: val.match is not a function</p>
  </blockquote>
  
  <p>I know that "a" return a good string value, because I've checked the logs.</p>
