1、Excel 密码保护的解除方法与解除原理:AAAABBBBAAA7Excel 弹出“您试图更改的单元格或图表受保护，因而是只读的。若要修改受保护单元格或图表，请先使用撤消工作表保护命令(在审阅选项卡的更改组中)来取消保护。可能会提示您输入密码。”窗口，如图 1。 出现这种情况，应该怎么解决呢？经过研究，找到了两种破解 Excel 工作表保护码的方法。一、VBA 宏代码破解法：第一步：打开该文件，先解除默认的“宏禁用”状态，方法是点击工具栏下的“选项”状态按钮，打开“MicrosoftOffice 安全选项”窗口，选择其中的“启用此内容”，“确定”退出(图 2)；再切换到“视图”选项卡，点击“宏
2、”“录制宏”，出现“录制新宏”窗口，在“宏名”定义一个名称为：PasswordBreaker(图 3)，点击“确定”退出；第二步：再点击“宏”“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“编辑”，打开“MicrosoftVisualBasic”编辑器，用如下内容替换右侧窗口中的所有代码：Sub PasswordBreaker()Dim i As Integer, j As Integer, k As IntegerDim l As Integer, m As Integer, n As IntegerDim i1 As Integer, i2 As Integer, i

Excel Key下载(下载地址：http:/ 5)。2. Advanced Office Password Recovery下载(下载地址：http:/ Excel 文件，马上就可以看到解出的密码了(图 6)。可以看出，用以上方法读出的密码完全不同，但
7、它们确实均可以解除该工作表的密码保护，这实在是个有趣的问题。在网上查找了许久，终于找到比较圆满的解释答案：当 Excel 工作表采用密码保护时，就会生成一个 16 位(双字节)长 hash 值。当输入密码进行验证时，真正进行比较的就是这个 hash 值。事实上，有很多不同的密码都可以生成同样的 hash 值。大家可以试试：当你用“test”(不含双引号)作为 Excel 工作表保护密码，你同样可以用“zzyw”(同样不含双引号)这个密码进行解锁。怎么样，神奇吧?Excel 对数据有很强的保护功能，可以对整个或部分数据隐藏、禁止复制和修改等，但有时候，由于忘记了密码，或者记不起以前自己到底做了哪
8、些改动，这种保护反而会为难自己。针对这种情况，我总结了几种解除保护的方法，供大家参考，并希望能够以此抛砖引玉。 一、解除单元格的保护1取消隐藏的行或列 被隐藏的行或列有一个明显的标志，那就是在行标题栏或列标题栏上有一条粗的黑线。取消隐藏的行或列的方法有两种，一种是直接拖动隐藏处的行或列标题使之变宽，也可以选中包含隐藏区域的行或列，通过“格式”菜单中的行列项目输入非 0 数值调整行高或列宽，使数据有足够的空间显示出来；另一种方法是选中包含隐藏内容的行或列区域，再通过“格式”菜单行列选项中的“取消隐藏”命令来恢复全部行列区域。2取消隐藏单元格或区域中的数据为了不让他人直接看到单元格的内容，一种简单
9、的方法就是把数据颜色设置成与背景色相同，这时我们只要拖选整个工作表即可让数据原形毕露；如果用图片、矩形框之类的非字符内容将重要数据遮盖，需要先用拖选方式找出工作表中的图片位置，再将其移开，激活被遮住的单元格，一般在公式编辑栏中就会显示其内容。若在单元格格式中使用了三个分号或空格之类的自定义格式，一般只要选中此单元格，在公式编辑栏中即可显示其内容，要想取消这种隐藏，可重新设置此单元格格式，在“数字”选项卡中选择“常规”即可。如果选中怀疑有数据的单元格后并没有在公式编辑栏中显示数据，不一定它就真的没有数据，我们只要看一下单元格的格式能否设置，若不能的话说明工作表被保护，如果不用密码可以取消工作表保
10、护的话，再在单元格格式设置中先查看数据格式是否为自定义，然后查看“保护”选项卡，看看是否已勾选了“隐藏”项，将这些都取消就可以知道单元格是否真的没有内容。当然，如果在撤消工作表保护时需要密码的话，我们将无可奈何，除非用户设置的密码很简单，那我就告诉你一个秘密，当密码的形式是“*123*”或“*abc*”时，我们可以分别用“*333*”或“*ccc*”来破解，星号表示任意字符，到底是什么只有靠猜了，这种方法对工作表和工作簿保护的密码也适应。3取消单元格数据的只读属性有时单元格中的数据虽然可见，但是我们既不能修改，也不能在当前工作表中复制，对于这种保护措施，取消的方法跟上面的第 2 点基本相同，只
11、要取消单元格格式设置对话框中“保护”选项卡中的“锁定”一项即可。当然还需要通过密码取消工作表的保护才行。 如果我们无法通过密码取消怎么办？你可以将其复制粘贴到其他工作表中，再在新的工作表中进行修改。二、解除工作表的保护查看是否有被隐藏的工作表，若菜单中有“格式工作表取消隐藏”项，则可通过此项取消隐藏的工作表。如果在菜单中也没有有效的“取消隐藏”项，仍然可能有被隐藏的工作表，这时我们可以任选一工作表右击，在弹出菜单中选择“查看代码”，然后在左窗格中的“Microsoft Excel 对象”列表中选择被隐藏的工作表，将其“Visible”属性值取“-1”退出即可，如图所示。如果工作表被密码保护，则
12、可复制当前表全部内容到另一张未保护的工作表中编辑。三、VBA 宏代码破解法：第一步：打开该文件，先解除默认的“宏禁用”状态，方法是点击工具栏下的“选项”状态按钮，打开“Microsoft Office 安全选项”窗口，选择其中的“启用此内容”，“确定”退出(图 2)；再切换到“视图”选项卡，点击“宏”“录制宏”，出现“录制新宏”窗口，在“宏名”定义一个名称为：PasswordBreaker(图 3)，点击“确定”退出；第二步：再点击“宏”“查看宏”，选择“宏名”下的“PasswordBreaker”并点击“编辑”，打开“Microsoft Visual Basic”编辑器，用如下内容替换右侧窗
