  <p>this is my code:</p>
  
  <pre><code>import os
  address = os.getcwd()
  import win32com.client as win32
  
  fname = address + "\\Bundles.xls"
  fname2 = address + "\\searchresults.xls"
  excel = win32.gencache.EnsureDispatch('Excel.Application')
  excel2 = win32.gencache.EnsureDispatch('Excel.Application')
  wb = excel.Workbooks.Open(fname)
  wb5 = excel.Workbooks.Open(fname2)
  
  wb.SaveAs(fname+"x", FileFormat = 51)
  wb5.SaveAs(fname2+"x", FileFormat = 51)    #FileFormat = 51 is for .xlsx extension
  wb.Close()
  wb5.Close()                               #FileFormat = 56 is for .xls extension
  excel.Application.Quit()
  excel2.Application.Quit()
  print('File .xls convert .xlsx successful!!')
  </code></pre>
