接受的答案在Windows 10上的Excel 2019中无法正常工作。找到了查看锁定宏所需的额外步骤。我正在总结步骤。

Add a .zip to the end of the excel filename and hit enter Once the file has been changed to a ZIP file, open it by double clicking on it Inside you would see a folder called xl like below Inside xl, you'll find a file called vbaProject.bin, copy/paste it on the desktop Go to the online Hexadecimal Editor HexEd.it Search for the following texts DPB=... and change them to DPx=... Save the file and close HexEd.it Copy/Paste the updated file from your desktop inside the ZIP file (you would need to overwrite it) Remove the .zip extension from the end of the filename and add the excel extention again. Open the file in excel - you may receive a couple of error notifications, just click through them.

====在接受的答案=====之外的额外步骤

Open the Visual Basic window (usually ALT+F11 if I remember correctly) and open the VBAProject properties (Tools menu). Click on the Protection tab and change (do not remove at this stage) the password to something short and easy to remember (we'll be removing in next step). Save the workbook and then close and reopen. Open again the Visual Basic window and enter the password you just put in. Redo the previous step but this time you can remove (delete) the password. Save the workbook and you have now removed the password.

是的，只要你使用的是。xls格式的电子表格(2003年以前Excel的默认格式)。对于Excel 2007以后，默认是.xlsx，这是一个相当安全的格式，这个方法将不起作用。

正如Treb所说，这是一个简单的比较。一种方法是使用十六进制编辑器(参见Windows的十六进制编辑器)简单地交换文件中的密码条目。循序渐进的例子:

Create a new simple excel file. In the VBA part, set a simple password (say - 1234). Save the file and exit. Then check the file size - see Stewbob's gotcha Open the file you just created with a hex editor. Copy the lines starting with the following keys: CMG=.... DPB=... GC=... FIRST BACKUP the excel file you don't know the VBA password for, then open it with your hex editor, and paste the above copied lines from the dummy file. Save the excel file and exit. Now, open the excel file you need to see the VBA code in. The password for the VBA code will simply be 1234 (as in the example I'm showing here).

如果你需要使用Excel 2007或2010，下面有一些其他的答案可能会有帮助，特别是这些:1、2、3。

编辑2015年2月:另一种看起来很有前途的方法，看看Đức Thanh nguy的新答案。

您可以尝试这种不需要HEX编辑的直接VBA方法。它将适用于任何文件(*.xls， *.xls， *.xls)。xlsm, *。xlam……)。

测试和工作:

Excel 2007 Excel 2010 Excel 2013 - 32位版本 Excel 2016 - 32位版本

它是如何工作的

我会尽我最大的努力解释它是如何工作的-请原谅我的英语。

The VBE will call a system function to create the password dialog box. If user enters the right password and click OK, this function returns 1. If user enters the wrong password or click Cancel, this function returns 0. After the dialog box is closed, the VBE checks the returned value of the system function if this value is 1, the VBE will "think" that the password is right, hence the locked VBA project will be opened. The code below swaps the memory of the original function used to display the password dialog with a user defined function that will always return 1 when being called.

使用代码

请先备份您的文件!

Open the file(s) that contain your locked VBA Projects Create a new xlsm file and store this code in Module1 code credited to Siwtom (nick name), a Vietnamese developer Option Explicit Private Const PAGE_EXECUTE_READWRITE = &H40 Private Declare Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _ (Destination As Long, Source As Long, ByVal Length As Long) Private Declare Function VirtualProtect Lib "kernel32" (lpAddress As Long, _ ByVal dwSize As Long, ByVal flNewProtect As Long, lpflOldProtect As Long) As Long Private Declare Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As Long Private Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long, _ ByVal lpProcName As String) As Long Private Declare Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As Long, _ ByVal pTemplateName As Long, ByVal hWndParent As Long, _ ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) As Integer Dim HookBytes(0 To 5) As Byte Dim OriginBytes(0 To 5) As Byte Dim pFunc As Long Dim Flag As Boolean Private Function GetPtr(ByVal Value As Long) As Long GetPtr = Value End Function Public Sub RecoverBytes() If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 6 End Sub Public Function Hook() As Boolean Dim TmpBytes(0 To 5) As Byte Dim p As Long Dim OriginProtect As Long Hook = False pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA") If VirtualProtect(ByVal pFunc, 6, PAGE_EXECUTE_READWRITE, OriginProtect) <> 0 Then MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, 6 If TmpBytes(0) <> &H68 Then MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 6 p = GetPtr(AddressOf MyDialogBoxParam) HookBytes(0) = &H68 MoveMemory ByVal VarPtr(HookBytes(1)), ByVal VarPtr(p), 4 HookBytes(5) = &HC3 MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 6 Flag = True Hook = True End If End If End Function Private Function MyDialogBoxParam(ByVal hInstance As Long, _ ByVal pTemplateName As Long, ByVal hWndParent As Long, _ ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) As Integer If pTemplateName = 4070 Then MyDialogBoxParam = 1 Else RecoverBytes MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, _ hWndParent, lpDialogFunc, dwInitParam) Hook End If End Function Paste this code under the above code in Module1 and run it Sub unprotected() If Hook Then MsgBox "VBA Project is unprotected!", vbInformation, "*****" End If End Sub Come back to your VBA Projects and enjoy.

对于.xlsm或.dotm文件类型，您需要以稍微不同的方式进行操作。

Change the extension of the .xlsm file to .zip. Open the .zip file (with WinZip or WinRar etc) and go to the xl folder. Extract the vbaProject.bin file and open it in a Hex Editor (I use HxD, its completely free and lightweight.) Search for DPB and replace with DPx and save the file. Replace the old vbaProject.bin file with this new on in the zipped file. Change the file extension back to .xlsm. Open workbook skip through the warning messages. Open up Visual Basic inside Excel. Go to Tools > VBAProject Properties > Protection Tab. Put in a new password and save the .xlsm file. Close and re open and your new password will work.

保护是Excel中的一个简单的文本比较。 在你最喜欢的调试器中加载Excel (Ollydbg是我选择的工具)，找到进行比较的代码并将其修复为总是返回true，这应该可以让你访问宏。

我的工具VbaDiff直接从文件中读取VBA，因此您可以使用它从大多数办公文档中恢复受保护的VBA代码，而无需求助于十六进制编辑器。
