破解密码加密的工作表excel

有些Excel 表格为了防止内容被修改，设置了保护工作表。 如何破解那修改那，就给大家一个示范

EXCEL工作表编辑资料，设置了工作表保护后，不能对表格进行插入删除操作。如果有密码，很简单:工具-选项—工作表保护——撤消工作表保护 就可以了。 如果忘记密码，如下操作： 1、打开文件

2、工具---宏----录制新宏---输入名字如:ha 3、停止录制(这样得到一个空宏) 4、工具---宏----宏,选ha,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:(完整复制下来即可) Public Sub ha()

6、闭编辑窗口

7、工具---宏-----宏,选AllInternalPasswords,运行,确定两次,等几分钟分钟(可能时间也挺长的半个小时是用不了的),再确定.OK,没有密码了!!

本程序我测试过了.，已经给客户完成修改工作，确实可行，就是破解时间长一些，Excel 可能还会出现无响应，大概一根烟卷的功夫就好了， （我是点击宏命令就去抽烟了了，回来点击两个确定就就好了，
