值得指出的是，如果您有一个Excel 2007 (xlsm)文件，那么您可以简单地将其保存为Excel 2003 (xls)文件，并使用其他答案中概述的方法。

Access、Excel、Powerpoint或Word文档上的VBA项目密码(带有扩展名. accdb . xlsm . xltm . docm . dotm . potm . ppsm的2007、2010、2013或2016版本)可以轻松删除。

这只是将文件名扩展名更改为. zip，解压缩文件，并使用任何基本的十六进制编辑器(如XVI32)来“打破”现有密码的问题，这会“混淆”Office，因此它会在下次打开文件时提示输入新密码。

步骤总结:

rename the file so it has a .ZIP extension. open the ZIP and go to the XL folder. extract vbaProject.bin and open it with a Hex Editor "Search & Replace" to "replace all" changing DPB to DPX. Save changes, place the .bin file back into the zip, return it to it's normal extension and open the file like normal. ALT+F11 to enter the VB Editor and right-click in the Project Explorer to choose VBA Project Properties. On the Protection tab, Set a new password. Click OK, Close the file, Re-open it, hit ALT+F11. Enter the new password that you set.

此时，如果您愿意，您可以完全删除密码。

完整的说明和我制作的“way back when”视频在YouTube上。

令人震惊的是，这种解决方法已经存在多年了，而微软还没有解决这个问题。

这个故事的寓意是什么?

Microsoft Office VBA项目密码不依赖于任何敏感信息的安全。如果安全性很重要，请使用第三方加密软件。

删除VBA项目密码的一个简单方法是执行以下操作:

将xlsm文件转换为zip 打开VBAProject.bin文件(我更喜欢使用notepad++ (https://notepad-plus-plus.org/downloads/)) 搜索DPB字段 用DPx替换它 保存文件 将zip文件转换为XLSM 打开excel文件 如果出现消息框，请单击“是” 为VBA项目属性设置新密码 关闭并再次打开该文件 输入新密码取消保护

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。

Colin Pickard is mostly correct, but don't confuse the "password to open" protection for the entire file with the VBA password protection, which is completely different from the former and is the same for Office 2003 and 2007 (for Office 2007, rename the file to .zip and look for the vbaProject.bin inside the zip). And that technically the correct way to edit the file is to use a OLE compound document viewer like CFX to open up the correct stream. Of course, if you are just replacing bytes, the plain old binary editor may work.

顺便说一句，如果你想知道这些字段的确切格式，他们现在有文档:

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:

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!
