title: Is there a way to edit/save an opening (in excel) xlsx file?
body: <p>I want to do something like this:</p>
  
  <pre><code>import openpyxl as x
  
  wb = x.load_workbook(filename)
  
  # do some edit to the workbook
  
  wb.save(filename)
  </code></pre>
  
  <p>The file specified by the filename is opening in Excel. Excel is locking the file so I will get permission denied error running the above code. Is there a way to edit/save it?</p>
