去除Excel工作表保护密码 绿色版

去除Excel工作表保护密码,很有用的小工具:)，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！

操作步骤：

1  打开需要破解密码的Excel；
2. Alt+F11，进入VBA编辑界面；
3. 插入 -- 模块(Module)；
4. 在右边Module的空白编辑区域，复制粘贴下面所有内容；
5. F5，运行该VBA命令；
