Excel vba 忘了密码 怎么办

Posted 2023-03-16

1、首先，如果文件格式是Excel 2010版（.xslm），需要先打开Excel文件，另存为2003版格式（.xls）。

2、然后用普通的文本编辑器（这里用的是NotePad++）打开这个文件，注意文件类型选“所有文件”。

3、然后在文件里查找“DPB"，把它改成“DPx”。注意大小写。

4、保存修改。然后用Excel重新打开这个文件。你会遇到一些错误，忽略它们。

5、然后进入Excel的“开发工具”面板，选择“Visual Basic”。又会有一系列错误，忽略它们，知道VBA项目打开。

6、这时候已经可以查看VBA代码了。如果想改变甚至去除原来的密码，继续看。从VBA编辑器的“工具”菜单，选择“VBA工程属性...“，然后转到”保护“面板。

7、在密码框中输入新密码。保存VBA文件和Excel文件，关闭Excel。重新启动Excel并重新打开这个文件，然后进入"开发工具"->"Visual Basic"，会提示输入密码。输入新设置的密码。

8、然后回到VBA编辑器的“工具”->"VBA工程属性"->“保护”，去掉密码以及保护选项前面的标记。最后保存文件即可。

1． 打开带密码的Excel,视图---宏----录制宏---（保存到）“个人宏工作簿”---点“确认”。
2． 查看宏----点“编辑”-----进入“Microsofe visual basic-PERSONAL.XLSB”页面；
3． 点“模块1“，弹出“模块1代码”----清除“模块1代码”里面的东西-----复制如下东西：

4． 点保存，然后关闭“BOOK1”
5． 点运行即可。 参考技术B

将你要破解的Excel文件关闭，切记一定要关闭呀！然后新建一个Excel文件，打开新建的这个Excel，按下alt+F11，打开vba界面，新建一个模块，将代码复制到这个模块中，代码如下：

Private Sub VBAPassword() '你要解保护的Excel文件路径
Filename = Application.GetOpenFilename("Excel文件（*.xls & *.xla & *.xlt）,*.xls;*.xla;*.xlt", , "VBA破解")
If Dir(Filename) = "" Then
MsgBox "没找到相关文件,清重新设置。"
Exit Sub
Else
FileCopy Filename, Filename & ".bak" '备份文件。
End If
Dim GetData As String * 5
Open Filename For Binary As #1
Dim CMGs As Long
Dim DPBo As Long
For i = 1 To LOF(1)
Get #1, i, GetData
If GetData = "CMG=""" Then CMGs = i
If GetData = "[Host" Then DPBo = i - 2: Exit For
Next
If CMGs = 0 Then
MsgBox "请先对VBA编码设置一个保护密码...", 32, "提示"
Exit Sub
End If
Dim St As String * 2
Dim s20 As String * 1
'取得一个0D0A十六进制字串
Get #1, CMGs - 2, St
'取得一个20十六制字串
Get #1, DPBo + 16, s20
'替换加密部份机码
For i = CMGs To DPBo Step 2
Put #1, i, St
Next
'加入不配对符号
If (DPBo - CMGs) Mod 2 <> 0 Then
Put #1, DPBo + 1, s20
End If
MsgBox "文件解密成功......", 32, "提示"
Close #1
End Sub

然后运行该宏，你会看到，打开了一个文件夹，找到我们要破解的这个文件，然后点击打开，稍等几分钟你就会看到破解成功的提示了。
