Excel弹出“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。可能会提示您输入密码。”窗口,如图1。

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);

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)。
