Hello, I noticed in http://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_excel.html#pandas.read_excel that `read_excel` can have a parameter `sheetname`set to `None` or a to a `list` In such a case a dictionary of `DataFrame` is returned. Maybe it should output an `OrderedDict` of `DataFrame` to preserve sheets order. Kind regards
