title: How can I convert a sheet to a string? Or do I even need to?
body: <p>I'm having a problem taking an xlrd document and placing it into an xlwt file to be saved. I keep getting the error:</p>
  
  <pre><code>decode() argument 1 must be string, not Sheet
  </code></pre>
  
  <p>How can I change a Sheet back into a string? here is my code:</p>
  
  <pre><code>import xlrd
  import xlwt
  wb = xlrd.open_workbook("Workbook1.xlsx")
  sh = wb.sheet_by_name("worksheet")
  wbk = xlwt.Workbook(sh)
  sheet = wbk.add_sheet("sheet1")
  </code></pre>
