出现这种情况,应该怎么解决呢?经过研究,找到了两种破解Excel工作表保护码的方法。
一、VBA宏代码破解法:
第一步:打开该文件,先解除默认的“宏禁用状态,方法是点击工具栏下的“选项状态按钮,打开“Microsoft Office安全选项窗口,选择其中的“启用此内容,“确定退出(图2);
点击看大图
再切换到“视图选项卡,点击“宏→“录制宏,出现“录制新宏窗口,在“宏名定义一个名称为:PassWordBreaker(图3),点击“确定退出;
第二步:再点击“宏→“查看宏,选择“宏名下的“PasswordBreaker并点击“编辑,打开“Microsoft Visual Basic编辑器,用如下内容替换右侧窗口中的所有代码:
Sub PasswordBreaker()
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
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 "One usable password is " & Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
ActiveWorkbook.Sheets(1).Select
Range("a1").FormulaR1C1 = Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
Exit Sub
End If
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub
第三步:再点击“宏→“查看宏,选择“宏名下的“PasswordBreaker并点击“执行,密码就现形了(图4)。
