各位朋友不知道有没有碰到过这样的情况，当你要打开一个EXECL工作表时，突然发现密码忘记了，唯一可做的也许是搞个破解软件来破一下，但针对打开后的工作表保护，一般就很难有效了，复制虽是一种办法，但不少数据（特别是公式较多着），可能就要乱套了，入户才能破解这一类密码呢？不久前在网上发现此精华，与大家共享一下！
利用宏运行方式破解，真的很有效，运行中可能电脑有两分钟无反应，千万不要以为死机了，等等吧！
步骤方法如下：
1.打开文件
2.工具---宏---录制新宏---输入名字如：aa
3.停止录制（这样得到一个空宏）
4.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：（复制吧）
6.关闭编辑窗口
7.工具---宏----宏。选AllInternalPasswords，运行，确定两次，等两分钟，再确定，OK，没有密码了！！
宏内容如下：
