你好
(1)EXCEL文件的加密：
先来看看如何针对EXCEL文件进行加密，首先打开要加密的EXCEL文件，然后选择菜单的“文件”->“另存为”，在打开的“另存为”窗口中选择右上角的“工具”->“WEB选项”。
之后就会自动弹出一个窗口，里面包括了对打开权限密码以及修改权限密码的设置选项，添加对应密码后确定即7a64e78988e69d83362可。
和WORD文档加密一样需要确认输入的密码，确认后关闭保存窗口。
这样每次打开该EXCEL文件后都会首先弹出打开密码输入对话框，只有输入正确的密码才能够查看里面的内容。通过以上几步完成了对EXCEL文档的加密工作。那么excel密码破解方法有哪些呢?
(2)EXCEL文档密码破解不求人：
根据提供的消息资料，就能了解到excel密码破解方法。和之前的操作一样通过Office password Recovery Toolbox打开要破解密码的文件，然后选择要破解的密码类型，点REMOVE按钮完成操作。
软件发送找到的EXCEL文件加密KEY信息，找到后发送到rixler software server服务器进行在线破解。
等待一段时间后弹出“the document has been successfully decrypted”提示后说明这个文件已经被成功破解掉了密码，点“确定”关闭软件。
之后会看到新建立的XXX(DEMO).xls文件，这个就是破解后没有打开密码以及修改密码限制的EXCEL文件，打开该文件可以看到与之前加密EXCEL文件一样的内容，输入信息也都是可
满意请采纳
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，顺序点击确定，OK,没有密码了!!

闪电般的破解 5秒斩杀Word文档密码 为Word文档加密本来无可厚非，但如果过段时间忘记了密码怎么办？虽然网络上充斥着各种破解软件，但它们无一例外的采用暴力破解方式，耗费时间长并且成功率低。我们今天将采用一种特殊的方法，在几秒内解除Word中的密码，让你的宝贵资料“失而复得”。 一、破解Word密码不是梦 其实我们利用的也是一款软件——Word Password Recovery Master（下载地址： /netfriends/0613/WPasRec.rar），解压缩软件后不必安装，直接运行WPasRec.exe，软件的使用方法更是简单，通过浏览按钮指定已经加密的Word文档，然后软件会自动识别该文档具备何种密码（如图1），此时相应的“Remove”按钮即可解除对应的密码。完成后会弹出如图2所示信息，整个过程非常快，但在破解中必须保证电脑已经连接到网络。 最后会在加密文档的同级目录下生成一个新文件，以“demo”标注，再次打开这个文件，或者点软件界面的“Open document in Microsoft Word”直接打开破解后的文档。在破解使用了10位密码加密并且文档容量在250KB的过程中只耗费了不到5秒种（图2）。 在破解过程中必须连接到网络，如果出现错误对话框可能是由于网络不稳定造e79fa5e98193e58685e5aeb9364成的，最好尝试重新破解。 二、Excel也别跑 Office Password Remover也是一款破解软件，它不但能解除Word密码，还可以破解Excel密码（下载地址： /netfriends/0613/OPRemovba.rar）。首先保证要破解的文件没被占用，然后指定加密文件进行破解（如图3），速度同样很快，但必须连接到网络。虽然这款软件也可以破解Word密码，但笔者还是推荐使用Word Password Recovery Master，因为经过测试它连接服务器相对更稳定。 用了这两款软件，再保密的Word（Excel）文件也能恢复回来，对付应急情况很管用。
