excel工具菜单中保护子菜单中撤销工作表保护命令的密码不知...-excel怎么撤销工作表保护,excel怎么撤销保护

• 首先打开你要清楚密码的工作表，点击那个有密码的工作簿，可以看到，现在这个工作簿有密码，是无法修改的，输入错误的密码也是无用

• 此时我们按“alt+f11”，进入到office的vba编辑模式，大家不熟悉也不要紧，后面都是很傻瓜的操作，进入之后，选择“插入”“模块”，之后出现一个白色的框了

• 复制一e799bee5baa6e78988e69d83337下代码到这个框中：

  Sub DeletePW()

  ActiveSheet.Protect DrawingObjects:=True, Contents:=True, AllowFiltering:=True

  ActiveSheet.Protect DrawingObjects:=False, Contents:=True, AllowFiltering:=True

  ActiveSheet.Protect DrawingObjects:=True, Contents:=True, AllowFiltering:=True

  ActiveSheet.Protect DrawingObjects:=False, Contents:=True, AllowFiltering:=True

  ActiveSheet.Unprotect

  End Sub

• 之后，按f5，运行，选择如图所示的，点击运行，把这个编辑器关了，回到刚才的表格，你可以发现已经可以编辑了，也无需输入密码了，这就是消除了保护密码。

录制一个新宏，然后编辑这个宏，将宏代码删除，将下列代码放入：

执行这个宏即可。

Excel工作表密码去除，破解

一、密码保护：

Microsoft Excel中的密码保护提供了几种类型：

利用密码以打开一个文抄档；

利用密码以修改文档；

利用密码以取消保护工作表；

利用密码以保护工作簿；

利用密码以保护共享工作簿。

二、当对Excel工作表进行保护操作后，不慎忘记了保护密码，导致无法编辑工作表，那么就要撤销密码保护。袭

1、对Excel工作表进行保护操作后，便无法再编辑工作表的内容了。

2、首先点击“开发工具”菜单，然后单击“录制宏”，在弹出的“录制新宏”小对话框中修改“宏名”，最后“确定zd”按钮。

3、在“代码”区域内单击“停止录制”的按钮，完成宏的录制。

4、再打开“宏”的对话框，选择新录制的宏，单击有变“编辑”的按钮，对刚才录制的宏进行编辑。

5、打开的宏的代码区域，删除该区域的原有的所有代码。将已经写好的代码粘贴在下图区域（具体代码可以直接通过百度获得），关闭代码编辑区域。

6、再次打开“宏”对话框，选择“PasswordBreaker”，单击右边“执行”按钮。

7、弹出Excel对话框，单击“确定”按钮，就可以发现Excel的密码保护九已经被撤销。
