您的excel文件扩展名更改为xml。 然后用记事本打开。 密码文本在XML文件中找到。

你看下面这条线;

Sheets("Sheet1").Unprotect Password:="blabla"

(抱歉我的英语不好)

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!

我基于Đức Thanh nguynun的精彩回答，让这种方法适用于64位版本的Excel。我在64位的Windows 7上运行Excel 2010 64位。

这对我来说很有效，我在这里记录了它，希望它能帮助别人。我还没有完全测试过。请确保在继续此选项之前保存所有打开的文件。

对于Windows 10机器上的Excel 2016 64位，我使用了十六进制编辑器来更改受保护的xla的密码(尚未对任何其他扩展进行测试)。 提示:在执行此操作之前创建备份。

我采取的步骤:

在十六进制编辑器中打开vba(例如XVI) 搜索这个DPB 将DPB更改为其他内容，如DPX 保存它! 重新打开.xla，将出现一条错误消息，继续。 您现在可以通过打开属性并转到password选项卡来更改.xla的密码。

我希望这对你们中的一些人有所帮助!

对于Excel 2007，您需要将文件扩展名更改为。zip 在存档中有一个子文件夹xl，在那里你会发现vbaProject.bin。 使用vbaProject.bin执行上面的步骤，然后将其保存回存档中。 修改回您的扩展名和voilà!(意思是遵循上面的步骤)

如果该文件是一个有效的zip文件(前几个字节是504b——用于.xlsm等格式)，那么解压缩该文件并查找子文件xl/vbaProject.bin。这是一个CFB文件，就像.xls文件一样。按照XLS格式的说明(应用于子文件)，然后压缩内容。

对于XLS格式，您可以使用本文中的其他一些方法。我个人更喜欢搜索DPB=块并替换文本

CMG="..."
DPB="..."
GC="..."

有空格。这样就避免了CFB容器大小的问题。
