撤销是不能撤销的，只能通过破copy解密码来实现，可以用修改后缀名称的方法。工具：华硕电脑1、首先找到Excel表格，修改后缀名称xlsx改为演示操作表格rar，如下图所示2、然后用压缩文件打开，然后打开xl，如下图所示3、然后把压缩文件里面找到的sheet1．xml文件，然后拖拽出来，然后要进行修改，如下图所示4、然后sheet1.xml文件打开用记事本打开，然后搜索protection，把图中的这zd一段代码，全部删除掉，如下图所示。5、再把修改后的sheet1．xml文件，选择拖拽到压缩的工作蒲中，选择替换掉就可以，如下图所示。6、把文件名称．rar重新更改．xlsx，然后再打开工作表保护就撤销了，如下图所示。本回答被网友采纳，原发布者:飞莲无解666如何破解EXCEL工作表保护密码忘记密码怎么办1.新建一个EXCEL工作表，而后点击另存为，讲表格保存为启用宏的工作表2.一次点击开发工具---录制新宏，在弹出的对话框内修改宏名称而后确定3.依次点击开发工具----停止录制宏，宏录制完成4.依次点击开发工具，---宏----在弹出的对话框找到我们刚才录制的宏名称而后进入VBA界面5.在VBA界面，全选里面的代码，而后删除，讲里面的代码全部删除完7a64e58685e5aeb9313334336237636.代码复制到VBA编辑窗口内PublicSubAllInternalPasswords() 'Breaksworksheetandworkbookstructurepasswords.BobMcCormick 'probablyoriginatorofbasecodealgorithmmodifiedforcoverage 'ofworkbookstructure/windowspasswordsandformultiplepasswords ' 'NormanHarkerandJEMcGimpsey27-Dec-2002(Version1.1) 'Modified2003-Apr-04byJEM:Allmsgstoconstants,and 'eliminateoneExitSub(Version1.1.1) 'RevealshashedpasswordsNOToriginalpasswords ConstDBLSPACEAsString=vbNewLine&vbNewLine ConstAUTHORSAsString=DBLSPACE&vbNewLine&_ "AdaptedfromBobMcCormickbasecodeby"&_ "NormanHarkerandJEMcGimpsey" ConstHEADERAsString="AllInternalPasswordsUserMessage" ConstVERSIONAsString=DBLSPACE&"Version1.1.12003-Apr-04" ConstREPBACKAsString=DBLS，按下面步骤操作，如果不会发邮件给我吧 SOUP5257@126.COM1\打开文件 2\工具e79fa5e98193e59b9ee7ad9431333262383635---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:(你复制吧) Option ExplicitPublic Sub AllInternalPasswords() ' Breaks worksheet and workbook structure passwords.

大家在日常使用的过程中，经常会制作一些不允许别人修改的工作簿，这个时候就会使用保护密码，但有时候如果忘记了保护密码，要怎么解除工作表与工作薄的保护密码呢？一起来看看吧！
方法
打开需要破解密码的Excel。
1、在进行编辑的excel地表的情况下中，那么就出现提示了无法进行编辑excel。2、然后需要进
按Alt+F11进入VBA编辑界面。
用宏代码破解密码：以office2007为例说明，（2003也是一样的，只是菜单命令的位置不同）
选择插入 ，点击进入 模块。
