EXCEL分享----用VBA代码解决工作表密码保护问题
 二维码 29

Content组最近遇到了比较多的受密码保护的EXCEL文档,这些文档不能编辑,我的解决办法就是破解密码。(没兴趣看邮件的同志们可以去百度~~)代码请查看下文




开发工具(Developer)(如果你的EXCEL上Developer还没有的话,请参看邮件“EXCEL分享--- 表单控件”,有讲解)--- Visual Basic---(前面两步可以用快捷键Alt+F11) 选择对象下任一工作簿---将代码复制粘贴到空白工作簿(当然你也可以插入(Insert)模块(Module)来放置代码)----运行(Run)(快捷键 F5)


简单的:一般文件密码被保护,打开Visual Basic界面的时候会有可以选择的工作簿给我们选择,直接双击任一一个(sheet1 or  sheet 2  or Thisworkbook 都可以)

稍微麻烦点:  如上图中遇到的,所有东西都被保护了。所以借助于一个新的Excel表格来实现工作簿的选择。如上图操作。


运行此代码后,会提示点击几次“确定”, 稍等下,就OK了。


要注意的是,不太会用这些的同志们,在用的时候不要打开其他重要的表格,以免运行错误。 还有,保存的时候可以先将Visual Basic界面打开,将里面的代码清空在直接保存,或者用另存为。


不是很了解宏代码之类,如果错误或疑惑,欢迎指出,此次为解燃眉之急也!
