title: Excel not showing a row but python displaying it
body: <p>I'm trying to read from an excel sheet in python:</p>
  
  <pre><code>&gt;&gt;&gt; import xlrd
  &gt;&gt;&gt; book = xlrd.open_workbook("file.xlsx")
  &gt;&gt;&gt; sheet = book.sheet_by_index(0
  ... )
  &gt;&gt;&gt; value = worksheet.cell(1,1)
  &gt;&gt;&gt; print(value)
  text:u'awx aaw('
  </code></pre>
  
  <p>But when I do the same for row 195, I get <code>error:29</code>:</p>
  
  <pre><code>&gt;&gt;&gt; value = sheet.cell(195,1)
  &gt;&gt;&gt; print(value)
  error:29
  </code></pre>
  
  <p>What does this mean? I can't even see anything "29" in the excel sheet. Row 195 is something else there. I even tried to unhide rows, but nothing happened. Please help, this is creating problems for the rest of program as well.</p>
