1、按住快捷键ALT+F11，然后切换出VBA编辑窗口，如图1所示。在窗口左侧，我们选择忘记密码的工作表，例如表1。
2、然后我们复制以下代码“Sub Pojie()ActiveSheet.Protect AllowFiltering:=True: ActiveSheet.UnprotectEnd Sub”，双击刚刚选中的工作表1后，在编辑窗口中输入刚刚复制的代码。
3、接下来，单击“运行” - “运行宏”。在弹出宏对话框中，我们再次单击“运行”。此时，先前加密的工作表将被解锁。重新开放后，可以直接进入。

1.视图—宏—录制新宏—输入宏名如:aa（aa是可随意输入）
2.停止录制，这样得到一个空宏
3.同样视图—宏—查看宏—选aa（aa为之前新建的宏）—点击编辑按钮
4.删除窗口中的所有字符，复制下面的内容粘贴。一个字母、标点符号都不能少。

付费内容限时免费查看回答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。
提问然后呢
回答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。
提问好难呀
回答、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。
提问为什么更换后缀后提示错误，说压缩文件格式未知
回答有解压软件吗
提问有的
回答更改后缀只适用于.xlsx

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*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

你的excel制作完成后，如果需要加密码，可以进行如下操作
1、excel制作完成，先要保存一下。
2、你打开“工具”--“选项”
，在“选项”下，你选择“安全性”一栏；
3、在“安全性”选项中，你可以看到两个项目a，此文件加密设置
打开权限密码
b，共享设置修改权限密码
这里你可以设置你的密码，如果你的表格需要共享的，建议你在设置共享密码的同时，在“建议只读”该项目上打钩（这样别人就只能看你的表格，但不能修改内容。
4、点“确定”，退出excel，然后你可以打开刚做的excel，看看打开表格时是否需要密码输入。
如果时间长了，忘记密码。可以再网上搜索破解excel、word的密码软件进行解密。
