body: <p>How to download an .xlsx file saved in a angular 2 project folder from a browser using blob. I am able to download a csv by using the following code:</p>
  
  <pre><code>return this.http.get(fileUrl, {headers: headerInfo})
      .map((response: any) =&gt; {
          return new Blob([response._body], {type: 'text/csv'});
