Excel用VBA去除工作表保护密码

Excel用VBA去除工作表保护密码
Excel 的工作表保护是非常脆弱的。

下面的VBA代码虽然不能找出工作表保护密码，但可以取消工作表保护，如果自己的工作表保护密码忘记了，可以用这个方法：
1.按Alt+F11，打开VBA编辑器。

2.在“工程”窗口中选择要取消保护的工作表名称，单击菜单“插入→模块”。

3.在右侧的代码窗口中输入下列代码：
Sub Remove_WorkSheet_Password()
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
If ActiveSheet.ProtectContents = False Then
MsgBox "该工作表没有保护密码！"
Exit Sub
End If
For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
If ActiveSheet.ProtectContents = False Then
MsgBox "已经解除了工作表保护！"
Exit Sub
End If
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub
4.关闭VBA编辑器，回到工作表中，按Alt+F8，打开“宏”对话框，选择“Remove_WorkSheet_Password”，并单击“执行”按钮。

稍等片刻工作表保护将被取消。

亲测可用。
