ExcelWriter not working
I get the below exception.

writer = pandas.ExcelWriter('output.xlsx')
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/IPython/core/interactiveshell.py", line 2538, in run_code
    exec code_obj in self.user_global_ns, self.user_ns
  File "<ipython-input-1-2e9db80bb8db>", line 1, in <module>
    writer = pandas.ExcelWriter('output.xlsx')
  File "/usr/lib/pymodules/python2.7/pandas/io/parsers.py", line 709, in **init**
    from openpyxl import Workbook
ImportError: cannot import name Workbook

Perhaps 'from openpyxl.workbook import Workbook' will help? This was suggested here: http://stackoverflow.com/questions/10439539/cannot-import-openpyxl-to-python-on-osx
