  在日常工作中,您是否遇到过这样的情况:您用Excel编制的报表、表格、程序等,在单元格中设置了公式、函数等,为了防止其他人修改您的设置或者防止您自己无意中修改,您可能会使用Excel的工作表保护功能,但时间久了保护密码容易忘记,这该怎么办?有时您从网上下载的Excel格式的小程序,您想修改,但是作者加了工作表保护密码,怎么办?您只要按照以下步骤操作,Excel工作表保护密码瞬间即破!
  1、打开您需要破解保护密码的Excel文件;
  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;
  从横线下开始复制

  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,就会出现以下对话框: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。如果是别人的文档,你又想恢复密码设置,就可以用此密码进行保护,他就能用他设置的密码打开,你可以试试,很有趣的。字母一定要大写):
