今天得到一个任务，是破解一个excel工作表的保护密码。我觉的网上的教程都挺好的，主要一点是注意excel中没有工具这一栏，需要自己去寻找出相关项。

用到的教程如下：

添加相关工具项

点击excel最左上角的标志（花）——最下方的excel选项——自定义——选择开发工具项——添加需要的工具项如宏安全性、查看宏、录制宏、visual basic——点击确定。

可以看到需要的工具项都已经在左上角出现了。

设置好工具栏宏，需要启用宏。

然后就下面就是按照教程来一步步操作即可。

1新建宏 录制新宏随便输入个名字如hong 点击“确定”按钮

2点击“停止录制”按钮或从菜单“停止录制”宏

3选择刚才所建的宏然后点击“编辑”按钮，会弹出代码编写窗口

4填写代码将下面的代码全部复制必替换原来的字符，填写完毕后关闭该窗口

//这里十分感谢原作者，因为经实践，确实好用。

6最后就来执行刚才所建的宏工具-宏-宏点击执行等带小段时间之后就可以看到效果了
