【实用】轻松破解Excel2007写保护密码图文教程

kcww

Microsoft发布Excel 2007时，引入了新的文件类型，即xlsx、xlsm、xltx，等等，称之为Open XML。因为这种新文件类型实质上是包含XML文件的包。如果将一个xlsx文件的扩展名修改为zip，那么能够看到组成该Excel文件的所有xml文档。

新的Open XML文件类型带来了许多好处。其主要的好处之一是可以通过操作组成文件的XML文档来简单地修改Excel 2007文件的内容和属性。

是的，当处理Open XML文件时，发现可以通过简单地编辑Excel文件里的xml文件，从而简单地移除工作表保护。

假设有一个工作簿，其工作表Sheet1被保护。现在，我希望取消该工作表的保护，但是不知道密码。怎么办呢？幸好这是Excel 2007，我们可以利用XML来移除工作表保护。

步骤1 首先备份工作簿，以防万一。

步骤2 修改工作簿文件的扩展名为zip。

步骤3 解压该压缩文件。

步骤4 找到代表目标工作表的XML文件（在xl\worksheets文件夹中）。

步骤5 使用任一XML编辑器打开代表目标工作表的xml文档。

步骤6 找到“sheetProtection”标签并移除该标签所在的行。

步骤7 保存已编辑的XML文档，用其取代原Zip文件中相应的XML文档。

步骤8 将文件的扩展名修改回xlsx。

至此，工作表保护已解除。

注意：

在XML文件中看到的任何密码都不是真正的密码。

这种方法不能取消对整个工作簿的保护。

还有一种方法是使用宏代码来取消的，代码附后：

VBA的工程密码如何取消？可以教我方法吗？
整个工作薄受保护，版本是2010版的，如何取消啊？

你好！楼主。我操作到减压就进行不下去了。提示文件损坏！我把后缀改回来这个文件就可以打开。
