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。

将整个表复制，粘贴到另一个表，粘贴时选择“选择性粘贴”－数值，这样就可以修改了。
或者你将表复制到word文档中编辑好后，粘贴到excel
工作簿
的另一个表中就行了。
