How to save a file (ajax request)?

Question

Django

ajax send a GET request to the server
then the server returns the xsl file, implementation :

response = HttpResponse(content_type='application/json')
        response['Content-Disposition'] = 'attachment; filename="team_maxes.xlsx"'
 
        wb = xlwt.Workbook()
          ....
        return response

and then on the client it is not possible to give this file to the user for downloading, I do this:

success: function (data) {
                        var bb = new Blob([data],{ type: 'application/vnd.ms-excel;charset=utf-8;',endings:'native'});                          
                         var bUrl = URL.createObjectURL(bb);
                         window.open(bUrl,"_self");
  }

A dialog box is shown to save the xsl file, but the data there is somehow unreadable. Excel says :
File format does not match file content !
Tell?
