Pandas: Looking up the list of sheets in an excel file

Question

The new version of Pandas uses the following interface to load Excel files:

read_excel('path_to_file.xls', 'Sheet1', index_col=None, na_values=['NA'])

but what if I don't know the sheets that are available?

For example, I am working with excel files that the following sheets

Data 1, Data 2 ..., Data N, foo, bar

but I don't know N a priori.

Is there any way to get the list of sheets from an excel document in Pandas?

Answer 1

You can still use the ExcelFile class (and the sheet_names attribute):

xl = pd.ExcelFile('foo.xls')

xl.sheet_names  # see all sheet names

xl.parse(sheet_name)  # read a specific sheet to DataFrame

see docs for parse for more options...

Answer 2

You should explicitly specify the second parameter (sheetname) as None. like this:

 df = pandas.read_excel("/yourPath/FileName.xlsx", None);

"df" are all sheets as a dictionary of DataFrames, you can verify it by run this:

df.keys()

result like this:

[u'201610', u'201601', u'201701', u'201702', u'201703', u'201704', u'201705', u'201706', u'201612', u'fund', u'201603', u'201602', u'201605', u'201607', u'201606', u'201608', u'201512', u'201611', u'201604']
