title: pandas pd.ExcelWriter and xlrd to output python dataframe as excel file
body: <p>I can print a dataframe using display (and it shows and it's correct), but when I output the same dataframe to a excel file I can't find the file? </p>
  
  <p>My code is:</p>
  
  <pre><code>from pandas import ExcelWriter
  import xlrd
  import openpyxl
  
  writer = pd.ExcelWriter('workbook_name.xlsx')
  merged_data.to_excel(writer,'sheet_name')
  </code></pre>
