excel有密码怎么破解
破解方法：1、将工作表的后缀名改为rar；2、打开文件，点击“Xl”，将sheet1文件移到文件夹中；3、记事本打开sheet1文件，删除“protection到0/处”的内容；4、修改后的文件替换原文件并改后缀名为xlsx。
excel文件被设置了密码怎么破解
打开文档后，通过文件菜单中“另存为”，将文档存为rtf格式。保存好文件后，先关掉文档再打开另存的文件，选择工具栏中的“解除文档保护”命令，不用填写密码就可以解除此文件的“文档保护功能”，而且任何信息都不会丢失。用Office Password Remover这个软件可以打开。
使用方法：
首先运行解压好的OPRemove.exe 这个程式，打开程式后能看到中间文本框后面有个类似目录的按钮。
选择后出现下图的画面，点击移除密码。
呆几秒钟后便出现“该文件已被成功破解”，点确定即可，这时候就大功告成了。 在这里要注意的是，破解后的文章名字会有点变化，加了“DEMO”这四个字母，翻译过来就是示范的意思，不必在意，重命名去掉就能了。
Excel设的密码怎样解除
用 excel的宏破解 法
1，打开需要解除保护的EXCEL工作表；
2，选择工具---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,旧的密码自动提示，工作表也自动解除保护了。
内容如下：==================================================================================

Excel文档加密，忘记密码了如何破解？
可以多试一下常用密码，大多数人设置密码一般都是设置的常用密码。或者使用密码找回的功能试一下。还可以先把密码写到记事本上，然后依次试一下。我之前有使用U盘加密超级3000加密了U盘上的文件后来忘记密码，就是将所有的密码写在记事本上一个一个的试出来的。
不要强制的破解哦。否则文件可能被损坏呢。
怎样破解EXCEL加密文件
工具：5秒WORD-EXCEL密码破解.exe
步骤如下：
1、百度“5秒WORD-EXCEL密码破解”，点击下方的连接，下载软件，软件不是很大，直接下载下来就可以了，下载下来是一个压缩包，解压该压缩包。打开压缩包解压出来的文件夹，第二个文件就是我们的密码破解工具，双击打开工具。
2、浏览，找到我们要破解的文件，点击确定，破解就开始啦。点击移除密码。
3、弹出对话框，点击确定，当然，电脑是要能联网的，相信你能看到这篇经验，电脑应该也是能联网的。
4、解密时间要看密码复杂程度，不过应该没有太变态的密码。
5、成功破解密码，并且生成了一个新的没有密码的文件。
excel文件密码忘记了怎么办 excel文档密码破解方法汇总
大家是不是还以为Excel密码破解是几乎做不到的事情？但事实刚好相反，借助Excel密码破解工具，Excel密码破解只需几秒钟的事情。
小编只为告诉大家一个简单的事实，Excel密码破解真的很简单。
强悍的Excel密码破解工具
与其说是Excel密码破解工具，不如说是Office文档密码破解工具更适合，因为这些Office密码破解工具都无一例外支持Word、Excel、PPT文档破解。我们先来看看有哪四大Excel密码破解工具吧。
4大破解工具
1、Accent OFFICE Password Recovery
特点：成功破解过的密码都会被记录下来用作下一次破解，破解已经破解过文档不费吹灰之力。
2、Office Password Remover
特点：在线秒杀所有采用普通加密方式的“.doc”、“.xls”、“.ppt”文档。
缺点：付款才能看到完整的被破解的文档，必须上网才能用。
3、Advanced Office Password Recovery
特点：功能无比强大，如果上面两款都破解不了，这款是最终武器。
4、Office Password Unlocker
特点：由于前三款Excel密码破解工具已经够用，这款功能其实也不差，但对笔者而言是凑数用。
方法：
先用Microsoft Office Excel 2003（可用金山WPS Office 2012 表格代替）创建一个“2003.xls”的普通方式加密Excel文档，然后用Office Password Remover这个在线破解工具来破解，1,2,3，3秒之后，就生产一个已经被成功破解的新Excel文档——2003（DEMO）.xls 。破解一个普通加密方式的Excel文档，只需3秒钟！如果你真的不信，可以自己测试一下！
3秒钟的事
当然，这个3秒破解Excel文档密码是有条件的。第一个条件：Excel文档保存格式必须为古老的“.XLS ”格式（同理，Word文档保存为“.DOC”格式，PPT文档为“.PPT格式”），第二个条件为加密方式必须为Office 2003或2007（WPS Office 2012）的默认加密方式。
注：要想得到完全的破解文件，需要付费，免费破解的Excel文档只能看到前几行。
Excel密码破解工具一秒能测试多少个密码？
如果不付费就破解不了，那就大错特错。要知道，在一台普通配置的电脑上，Excel密码破解工具一秒能测试约88万个密码（需符合以上两个条件）。假设一个6位数的全数字密码，你猜要多长时间来破解？答案是2秒不到（破解时间因测试环境不同而不同）。
Excel密码破解工具一秒能测试约88万个密码
WPS表格（用途相当于Excel）虽然提供多种加密方式，但其中的XOR加密方式在Advanced Office Password Recovery里就形成虚设。可能是Advanced Office Password Recovery已经掌握了怎么完美破解XOR加密方式的方法，否则不可能做到无论你设置什么密码，都会被瞬间打开！
小编在此强调一下，这不代表WPS Office 2012 的加密方式不行，只是想说明，Excel加密要选对加密方式才靠谱，后面就是详细讲解这个。
总结：从另一个角度探讨看XOR加密方式，XOR加密方式虽然可以被 Advanced Office Password Recovery 瞬间破解，但却完全不怕Office Password Remover的在线破解。因为Office Password Remover对XOR加密方式的Office 文档无可奈何。如果有人想找随时找回密码的加密方式，那WPS内置的XOR加密毫无疑问是最适合的方式。
