有没有办法使用十六进制编辑器取消保护Excel工作表（* xls）？

Question

我正在阅读此post，他们描述了一种在excel（V.2003或.xls）中打开受密码保护的VBA项目的方法。我想知道是否有类似的方法来取消保护excel表？

非常感谢。

假设Sheet2受密码保护。打开工作簿。选择sheet2。在sheet2的窗口中粘贴下面的代码。选择运行代码的所有代码。它会给你一个信息。只需关闭消息和vba窗口。 Sheet2未受保护。

    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)
                Exit Sub
            End If

          Next: Next: Next: Next: Next: Next
        Next: Next: Next: Next: Next: Next

    End Sub
