1、工作表写入保护，忘记密码，解决办法：
流程如下：
1打开文件
2工具---宏----录制新宏---输入名字如:aa
3停止录制(这样得到一个空宏)
4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：

或者参考如下内容：
是打开文件需要密码？还是文件打开后设置的修改密码？他们方法不同的，我都用过。（符件中的移除密码，是移除打开文件时需要的密码，无需安装，打开即用，很简单。），如果是能
打开文件，需要取消单元格的修改密码，方法如下：
先打开EXCEL文件，然后点“录制宏”，随便录一下就可以了，然后打开“宏”选“编辑”，将里面的内容全部换成以下文本，然后执行。几分钟后，即可解掉密码。
