解密excel文件 [英] decrypt excel files

问题描述

我有 1000 个加密的工作簿，我想通过提供密码来解密.我在apache poi或python的xlrd模块下找不到解密方法.

Hi I have 1000 encrypted workbooks which I would like to decrypt by providing a pwd. I could not find a decrypt method under apache poi or python's xlrd module.

有谁知道可以处理这个问题的库(wbc.decrypt(pwd)).我更喜欢我可以从 unix 框中使用的库.

Does anyone know a library which could handle this (wbc.decrypt(pwd)). I would prefer a lib i could you use from a unix box.

谢谢

推荐答案

使用 COM 绑定调用 Unprotect 方法.

Use the COM bindings to call the Unprotect method.

import win32com.client

excel = win32com.client.Dispatch('Excel.Application')

workbook = excel.Workbooks.open(r'c:\mybook.xls', 'password')

workbook.SaveAs('unencrypted.xls')

另存为可以应用新密码.请参阅:http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.workbook.saveas%28VS.80%29.aspx

SaveAs can apply a new password. See: http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.workbook.saveas%28VS.80%29.aspx
