excel表格打开设置密码了 可是现在忘了密码怎么办
1、按住快捷键ALTF11，然后关闭VBA编辑窗口，如图1所示。在窗口的左侧，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“subJie()activesheet.protectallowfiltering:=true:activesheet.unprotecttendsub”。双击刚刚选定的工作表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。在弹出的宏对话框中，我们再次单击“运行”。此时，先前加密的工作表将被解锁。重新打开后，您可以直接进入。
工作表被保护了，打不开怎么办？一招破解其密码
有时候我们为了防止别人修改工作表内容，经常我们会设置工作表保护密码，但是有时候我们忘记了密码或者编辑人没给我我们密码，怎么办呢？别怕这个对于libora老师还是蛮简单的，让我教你一招破解她！
具体操作步骤：
第一步：修改工作表后缀，将工作表名称后缀中的 .xlsx 修改为.rar（修改后悔变成一个压缩包）；
第二步：查找压缩包里面的sheet1.xml文件（如果你需要修改sheet1的内容，你就选择sheet1.xml，如果修改别的sheet，你就选择sheet2或者sheet3），打开压缩包→xl文件夹→worksheets→sheet1.xml，选中sheet1.xml复制出来；
第三步：记事本打开sheet1.xml文件；
第四步：删除工作表保护编程。记事本打开后，ctrl+F调出查找窗口，输入protect搜索，找到编程并删除（编程为下图中选中蓝色区域），修改后关闭记事本；
第五步：将文件放回原位置和改回后缀。1.文件放回原位置：打开压缩包→xl文件夹→worksheets→删除原来sheet1.xml→放回修改后的sheet1.xml。2.文改回后缀：将 .rar 后缀改回 .xlsx 。
第六步：打开工作表检查破解情况。打开工作表尝试修改内容，检查密码是否已经破解。
1.首先将excel表格的文件后缀名 .xlsx更改为 .rar。
2.通过压缩文件打开这个表格，并找到下面的路径，xl——worksheets——sheet1.xml
3.在压缩文件里的sheet1.xml文件拖出来。
4.用记事本方式将.sheet1.xml文件打开，然后搜索，“protection”，将这段代码删除。即<sheetprotection.........="0"/>这一段。
5.把已经修改后的sheet1.xml文件，拖拽到压缩的工作蒲中，然后选择替换，确认即可。
6.，把文件名称，“演示操作表格.rar”重新更改“演示操作表格.xlsx”，这样就可以将之前设置的密码取消了。excel表格就可以正常打开了。

3)解除限制
只需等待几秒，软件即可成功移除文件的限制密码。
有两种方法可以解决：
方法1：使用密码破解程序破解。以下为具体方法：
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,确定两次,等2分钟,再确定.OK,没有密码了!!
内容如下：

再用该密码给保护，原来使用者的密码同样能打开。
方法2：使用压缩包解决。
将文件后缀名改为RAR。
打开压缩包文件，找到一个xml文件，用文本方式打开。
打开之后，找到代码pssword 语句，将该句删掉。
再将后缀名改为xls，再打开就没有密码了。
