excel工作表保护密码破解(可行有效) 的方法
作者:桑三 日期:2010-08-31
一个excel文档要修改其中的内容,可是被保护了,怎么也修改不了。找了一堆破解软件,要么需要购买,要么是破解打开密码的,非保护密码。好不容易找到解决方案!现在给大家分享下。
excel工作表保护密码破解(可行有效) 的方法:
1、打开被保护的excel工作表;
2、工具---宏----录制新宏---输入一个宏名,如宏名为sangsan;
3、确定后出来一个可以点停止的东西,点停止录制(这样得到一个空宏);
4、工具---宏----宏,选刚才录制的宏,如宏名为sangsan的,再点编辑按钮;
5、删除代码框中的所有文字,用下面的代码复制粘贴进去,然后关闭(会自动保存的);
6、回到工作表,点工具-宏选AllInternalPasswords,再点右边的执行;
7、出来两次点确定,然后就开始破解密码了,等几分钟(密码复杂可能更久)有就会提示你密码,同时保护excel工作表保护密码也去掉了,可以正常修改录入数据了。至此破解成功。
