有两种方法可以解决：
方法1：使用密码破解程序破解。以下为具体方法：
1\打开文件
2\工具---宏----录制新宏---输入名字如:aa
3\停止录制(这样得到一个空宏)
4\工具---宏----宏,选aa,点编辑按钮
5\删除窗口中的所有字符(只有几个),替换为下面的内容:(复制吧)
6\关闭编辑窗口
7\工具---宏-----宏,选AllInternalPasswords,运行,确定两次,等2分钟,再确定.OK,没有密码了!!
内容如下：

再用该密码给保护，原来使用者的密码同样能打开。
方法2：使用压缩包解决。
将文件后缀e79fa5e98193e58685e5aeb9366名改为RAR。
打开压缩包文件，找到一个xml文件，用文本方式打开。
打开之后，找到代码pssword 语句，将该句删掉。
再将后缀名改为xls，再打开就没有密码了。
快速破解
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，e799bee5baa6e997aee7ad94e78988e69d83330一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
