Excel撤销工作表保护密码的破解并获取原始密码

在日常工作中，您是否遇到过这样的情况：您用Excel编制的报表、表格、程序等，在单元格中设置了公式、函数等，为了防止其他人修改您的设置或者防止您自己无意中修改，您可能会使用Excel的工作表保护功能，但时间久了保护密码容易忘记，这该怎么办？有时您从网上下载的Excel格式的小程序，您想修改，但是作者加了工作表保护密码，怎么办？您只要按照以下步骤操作，Excel工作表保护密码瞬间即破！
1、打开您需要破解保护密码的Excel文件；
2、依次点击菜单栏上的工具---宏----录制新宏，输入宏名字如:aa；
3、停止录制(这样得到一个空宏)；
4、依次点击菜单栏上的工具---宏----宏,选aa,点编辑按钮；
5、删除窗口中的所有字符(只有几个),替换为下面的内容；

6、关闭编辑窗口；
7、依次点击菜单栏上的工具---宏-----宏,选AllInternalPasswords,运行,确定两次；
等一会,就会出现以下对话框：这就是Excel密码对应的原始密码(此密码和原先设置的密码都能打开此文档。如果是别人的文档，你又想恢复密码设置，就可以用此密码进行保护，他就能用他设置的密码打开，你可以试试，很有趣的。字母一定要大写)：





再点击确定。Excel的原始密码就被清除了!!
