破解密码保护Excel文件的方法

　　方法一，要是我们知道密码，直接打开Excel，点“工具”――》“保护”――》“撤消工作簿保护”，弹出窗口后输入密码就行。

　　方法二，没有密码的话，我们可以用“宏模块”来破解，具体步骤看下面。

　　1、打开要处理的Excel文件，然后按“ALT”+“F11”，就像下图那样。

　　2、接着点菜单上的“插入”――“模块”，如图所示。

　　3、把下面这段代码复制，粘贴到空白的地方；

　　代码如下

　　复制代码

　　4、好了，确定没问题后按一下“F5”运行宏模块，开始密码破解。先点击确定，之后就能看到红框处的密码数字了

　　5、完成之后，再去尝试编辑Excel，就不会有任何问题了哦。

　　需要注意的是，破解他人加密的Excel文件可能会涉及隐私问题，一定要在合法合规的前提下使用这些方法，可不能乱用哦。

　　你有没有遇到过破解Excel密码的情况呀？用这些方法尝试的时候顺利吗？可以在评论区说说你的经历。
