使用宏命令取消EXCEL工作表保护

使用宏命令取消EXCEL工作表保护

作者:嘟嘟鱼 时间:2013-10-18 分类:技术 评论:0条 浏览:47954

帮朋友修改一个excel文档,没想到被加了密码,不能编辑,提示“您试图更改的单元格或图表受保护,因而是只读的。若要修改受保护单元格或图表,请先使用‘撤消工作表保护’命令(在‘审阅’选项卡的‘更改’组中)来取消保护”。然后提示输入密码。。。

google一下找到了个靠谱的方法,自己收藏一下:

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。如果没有密码,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:a
3. 停止录制(这样得到一个空宏)
4. 工具—宏—-宏,选a,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:(复制下来)

6. 关闭编辑窗口
7. 工具—宏—–宏,选AllInternalPasswords,运行,确定两次,等2分钟(确实有这么长时间),再确定.OK。
没有密码了,继续干活。
