做数据分析的人都知道，原始数据的正确性是非常重要的，常常会因为一个数据的错误，导致结果发生很大的偏差。
因此在工作表中将原始数据输入完成并校对后，为了防止误操作或是被他人随意复制，都会选择将这些数据进行保护。
但随着现代生活节奏的加快，再加上使用密码的地方太多，因此忘记密码的事情也是常有发生。当辛辛苦苦做的一份工作表因为忘记密码再也不能进行修改时，是不是感觉很郁闷呢？
这时该怎么办呢？重做一份吗？其实不用这么麻烦，下面我就为大家分享两种常用的清除工作表保护密码的方法。
利用VBA清除
1、点击菜单栏中的“开发工具”，选择录制宏，录制一个名为“清除工作表保护密码”的宏文件（可以根据自己的习惯命名该宏文件）。
2、再次点击菜单栏中的“开发工具”，选择“宏”，打开宏对话框，“宏名”选择刚刚新建的宏文件，然后点击“编辑”，打开宏（VBA）编辑窗口。
3、在宏（VBA）编辑窗口的左侧依次选择“VBAProject PERSONAL,XLSB”→“模块”→“模块2”后，将右侧的代码窗口中的原有内容删除后，把以下代码复制后粘贴在代码窗口中保存。
4、再次点击菜单栏中的“开发工具”，选择“宏”，打开宏对话框，“宏名”选择刚刚新建的宏文件，然后点击“执行”或“单步执行”，等程序运行完成后工作表保护密码就清除了。（提示：程序运行时有点卡，如果电脑配置低就选择单步执行，效果是一样的）
VBA代码如下：
Public Sub 工作表保护密码破解() Const HUANHANG As String = vbNewLine & vbNewLine Const MINGCHEN As String = "清除工作表保护密码" Const JINGGAO As String = "该工作簿中的工作表密码保护已全部清除!!" & HUANHANG & "请记得另保存" _ & HUANHANG & "注意：不要用在不当地方，要尊重他人的劳动成果！" Const TISHI1 As String = "该文件工作表中没有加密" Const TISHI2 As String = "该文件工作表中没有加密2" Const KSPJ As String = "解密需花费一定时间,请耐心等候!" & HUANHANG & "按确定开始清除!" Const FXMM1 As String = "密码重新组合为:" & HUANHANG & "$$" & HUANHANG & _ "如果该文件工作表有不同密码,将搜索下一组密码并修改清除" Const FXMM2 As String = "密码重新组合为:" & HUANHANG & "$$" & HUANHANG & _ "如果该文件工作表有不同密码,将搜索下一组密码并解除" Const MSGONLYONE As String = "确保为唯一的?"
