title: Pandas Excelwriter, writer.save()
body: <p>Pandas <strong>Excelwriter</strong>, <strong>writer.save()</strong>
  the command is saving the file in read-only mode.
  Does it have an option to <strong>save the file in write mode</strong>.</p>
  <p>Problem: When i am trying to copy the cell values (through python coding) from the file created from writer.save(), its says that the value is <strong>read-only</strong>.
  Note: I am working with xlsx files.</p>
