表格受密码保护时,我们修改数据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。 | |
可能会提示输入密码。这时候我们可以用VBA宏代码破解法来破解表格保护密码: | |
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” | |
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,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 | |
第四步:点击“撤消工作表保护”,然后输入密码即可解除锁定; | |
测试结果,密码破解可用,但是很晕的是破解的密码跟原来的密码有很大的差距,想不明白了,反正能用就好。 |
