熊貓無法打開這個Excel文件

Question

我想用python熊貓打開一個Excel文件。代碼很簡單，如下所示;

import pandas as pd 
df = pd.read_excel('../TestXLWings.xlsm', sheetname="TestSheet") 

我在下面的錯誤;

Traceback (most recent call last): 
    File "C:\Program Files\JetBrains\PyCharm Community Edition 2017.2\helpers\pydev\pydevd.py", line 1599, in <module> 
    globals = debugger.run(setup['file'], None, None, is_module) 
    File "C:\Program Files\JetBrains\PyCharm Community Edition 2017.2\helpers\pydev\pydevd.py", line 1026, in run 
    pydev_imports.execfile(file, globals, locals) # execute the script 
    File "C:\Program Files\JetBrains\PyCharm Community Edition 2017.2\helpers\pydev\_pydev_imps\_pydev_execfile.py", line 18, in execfile 
    exec(compile(contents+"\n", file, 'exec'), glob, loc) 
    File "C:/Users/testing/Dropbox/Test-XLwings/test.py", line 3, in <module>

    File "C:\ProgramData\Anaconda3\lib\site-packages\pandas\io\excel.py", line 203, in read_excel 
    io = ExcelFile(io, engine=engine) 
    File "C:\ProgramData\Anaconda3\lib\site-packages\pandas\io\excel.py", line 260, in __init__ 
    self.book = xlrd.open_workbook(io) 
    File "C:\ProgramData\Anaconda3\lib\site-packages\xlrd\__init__.py", line 441, in open_workbook 
    ragged_rows=ragged_rows, 
    File "C:\ProgramData\Anaconda3\lib\site-packages\xlrd\book.py", line 87, in open_workbook_xls 
    ragged_rows=ragged_rows, 
    File "C:\ProgramData\Anaconda3\lib\site-packages\xlrd\book.py", line 595, in biff2_8_load 
    raise XLRDError("Can't find workbook in OLE2 compound document") 
xlrd.biffh.XLRDError: Can't find workbook in OLE2 compound document 

我的Excel文件是xlsm並受密碼保護。 OLE2複合文檔究竟意味着什麼？熊貓在打開這種Excel文件時是否有問題？我正在使用python v3.6

Answer 1

我會回答我自己的問題。在ayhan的評論之一中，Excel保護的文件不能被xlrd讀取。一個解決方案是取消保護。

I need the command to unprotect an Excel file from python

另一種解決方案來讀取Excel中保護的文件是使用xlwings。我已驗證xlwings能夠在Excel文件打開時讀取受保護的Excel文件。
