1. excel中工作表保护密码忘记了
1、先找到有工作表保护密码的Excel表格，然后将忘记密码的Excel文件名称后缀由 .xlsx改为 .rar，如果有提示可以忽略，一般不会造成什么影响。
2、用压缩文件打开忘记密码的Excel文件，然后按以下步骤进行操作：xl——worksheets——sheet1.xml（这里是将sheet1工作表设置了保护密码，可根据实际情况选择相应文件名）。
3、从压缩文件里面找到sheet1.xml文件，然后拖拽至一个方便找到的位置（因为我们要对其要进行修改） 。然后将sheet1.xml文件右击选择用记事本打开方式打开。
4、然后搜索，“protection”，把从这一段代码，全部删除掉。
5、然后再把修改后的sheet1.xml文件，选择拖拽到压缩的工作薄中，选择替换掉即可，点击确定。
6、最后一步，和第一步相反，把文件名称后缀，由“演示表格.rar”重新更改“演示表格.xlsx”。最后打开Excel表格，你会惊喜地发现是不是保护密码都取消了吧
2. excel中工作表保护密码忘记了怎么办
步骤1、打开手机，点击【手机管家】-【进入权限隐私】；
步骤2、进入后点击【应用加密】，如果之前设置了相应的【密码】，是需要输入才可以进入的；
步骤3、不记得就随意输入，下方会出现【忘记密码】，点击会出现之前设置的【密保问题】，输入【相应答案】，就可以【重新设置密码】；
步骤4、如果【密保问题】也忘记了，就需要【恢复出厂设置】来清除密码了，记得备份重要资料；
步骤5、主界面点击【设置】-进入【其他设置】；
步骤6、进入【备份与重置】，进行【相关清理】即可；
备注：如果每次进入加密文件输入密码觉得麻烦，有指纹解锁的机型可以在【应用加密】-【设置】-【使用指纹解锁来打开应用】，可以操作看看。
以上就是应用加密忘记密码了怎么办的步骤，希望给健忘的朋友们有多一个解决方法

1、Excel启动工作表保护后，如果忘记取消工作表保护时使用的密码，则不能对工作表进行编辑。单击“开发工具”菜单，单击“录制宏”，在弹出的“录制新宏”对话框中修改“宏名”，最后单击“确定”按钮。
2、在“代码”区域单击“停止录制”按钮，完成宏的录制。按快捷键 AIT + F8 打开 “宏”对话框，选择新录制的宏，单击“编辑”按钮，对刚才录制的宏进行编辑。
3、打开的宏的代码区域，删除该区域的所有代码。将写好的代码粘贴在该区域，关闭代码编辑区域。
4、再次打开“宏”对话框，选择“PasswordBreaker”，单击“执行”按钮。弹出Excel对话框，单击“确定”按钮，便可以发现Excel的密码保护已经被撤销。
撤消保护工作表后，还可以在“审阅”选项下对工作表重新进行进行保护和撤消保护工作表操作。
