　　Excel密码破解方法有很多，最常见的便是使用密码字典去解读，解读成功即为破解，而本次使用的是宏命令，若是你还在一筹莫展，可以看看下文中的方法，因为涉及Excel重要文件，若是别人的东西，请获取授权！

　　Excel密码破解方法介绍：

　　1、进入加密的 Excel 用快捷命令Alt+F8 打开宏命令 窗口。

　　2、在宏名一栏中 输入宏的名字 随意健入即可。

　　3、输入完宏名后 创建的按钮就亮了 点击创建 我们就可以来到 新的界面了。

　　4、将编辑框内的Sub knife( )End Sub删除 将下列代码 复制 上去。

　　5、关闭 宏窗口 回到Excel下 按ALT+F8 重新打开 宏命令窗口。

　　6、你会发现 你前面输入的宏名 变成了AllInternalPasswords 点击执行 会出现如下对话框 点确定。

　　7、一直点 确定 直到不在 出现对话框为止。

　　8、等待 一段之间之后 系统会 再次跳出对话框 再点确定 保护就破解成功了。

　　！！！注：以上方法仅作为参考教材，请勿用于非法途径。

　　以上内容便是Excel密码破解方法的操作步骤，下次请用户在设置Excel密码的时候尽可能的简单一些，并记录下密码备份，避免再次需要使用宏。
