EXCEL工做表保护密码破解 宏撤销保护图文教程

今天获得一个任务，是破解一个excel工做表的保护密码。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，须要本身去寻找出相关项。

用到的教程以下：

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——添加须要的工具项如宏安全性、查看宏、录制宏、visual basic——点击肯定。

能够看到须要的工具项都已经在左上角出现了。

设置好工具栏宏，须要启用宏。

而后就下面就是按照教程来一步步操做便可。

1新建宏 录制新宏随便输入个名字如hong 点击“肯定”按钮

2点击“中止录制”按钮或从菜单“中止录制”宏

3选择刚才所建的宏而后点击“编辑”按钮，会弹出代码编写窗口

4填写代码将下面的代码所有复制必替换原来的字符，填写完毕后关闭该窗口

//这里十分感谢原做者，由于经实践，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以后就能够看到效果了
