本办法只能破解后缀为xls的Excel文件,如果后缀为xlsx的Excel文件可先把该文件转换为2003版Excel文件后尝试破解。
一、通过找出密码破解:
1、打开您需要破解保护密码的Excel文件;
2、依次点击菜单栏上的工具---宏----录制新宏,输入宏名字如:aa;
3、停止录制(这样得到一个空宏);
4、依次点击菜单栏上的工具---宏----宏,选aa,点编辑按钮;
5、删除窗口中的所有字符(只有几个),替换为下面的内容;

横线中间的部分

6、关闭编辑窗口;
7、依次点击菜单栏上的工具---宏-----宏,选AllInternalPasswords,运行,确定两次; 等一会(有1~2分钟),就会出现一个对话框 
:这就是Excel密码对应的原始密码(此密码和原先设置的密码都能打开此文档)。

P.S:按“确定”后将清除excel的密码,若此excel是他人的,而你只是想获取密码,则在关闭文件时“您是否保存对XXX的更改”选“否”即可

二、暴力删除破解:
使用方法: 
1、打开新文件excle, 按ALT+F11, 双击左侧工程ThisWorkbook表单, 把代码拷贝在右面的窗口里;
2、打开密码保护的工作表,运行该宏程序,即可破解工作表密码
