VBA是脚本语言，可直接看到代码（VB的语法），所以需要你对VB这种编程语言有一定的了解。或者贴出来让大家帮你看看
Excel是一个专门用于整理数据的电子表格，为了保障表格的安百全，用户可以为文档进行加密，可以设置以下类型密码：打开密码、编辑密码、工作度表密码、共享账簿密码以及VBA密码。VBA全称是VisualBasicforApplications，是微软开发出来在其桌面应用程序中执行通用的自动化(OLE)任务的编程语言。VBA是VisualBasic的一种宏语言，主要能用来扩展Windows的应用程式功能，特知别是MicrosoftOffice软件，特别是Excel表格。另外，也可说VBA是一种应用程式视觉化的Basic脚本道。实际上VBA是寄生于VB应用程序的版本，可以具备VBA的宏功能。VBA密码就是回为变成语言设置访问权限。破解VBA密码有两种方法：1、使用宏代码，这种方法比较专业，不具有普遍的适用性；2、使用专业的第三方密码破解工具答，这个可以广泛被使用，传播比较广泛的是AdvancedOfficePasswordRecovery，使用软件打开Excel文档，程序会自动开始破解VBA密码的操作，一旦破解成功，用户可以更改Excel文档的VBA密码，重新获取权限。
关于破解EXCEL VBA工程密码的方法,以下代码非常有效,首先建一新EXCEL文件,在工作表标签处右点>>查看代码>>复制以下代码>>按F8执行在弹出窗中选你要你破解工程密码的EXCEL文件 >>再按F5执行即可.
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e79fa5e98193e78988e69d83333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
If Protect = False Then
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"
End If
Close #1

首先，尝试打开工作簿时，提示有密码：

点击运行：
破解过程需要几分钟，有几次对话框弹出，都是英文的，留意对话框中如下内容：
标注部分即为密码。虽然不是原始密码，但是用这个密码照样可以打开工作簿的。
