撤銷工作表保護密碼忘了怎麼辦

做資料分析的人都知道,原始資料的正確性是非常重要的,常常會因為一個資料的錯誤,導致結果產生很大的偏差。

因此在工作表中將原始資料輸入完成併校對後,為了防止誤操作或是被他人隨意複製,都會選擇將這些資料進行保護。

但隨著現代生活節奏的加快,再加上使用密碼的地方太多,因此忘記密碼的事情也是常有發生。當辛苦做的一份工作紙因為忘記密碼再也不能進行修改時,是不是覺得很鬱悶呢?

這時該怎麼辦?重做一份嗎?其實不用這麼麻煩,下面我就為大家分享兩種常用的清除工作表保護密碼的方法。

利用VBA清除

1、點擊選單列中的“開發工具”,選擇錄製宏,錄製一個名為“清除工作表保護密碼”的宏文件(可以根據自己的習慣命名該巨集文件)。

2、再次點擊選單列中的“開發工具”,選擇“巨集”,開啟巨集對話框,“巨集名”選擇剛剛新建的巨集文件,然後點選“編輯”,開啟巨集(VBA)編輯視窗。

3、在巨集(VBA)編輯視窗的左側依序選擇「VBAProject PERSONAL,XLSB」→「模組」→「模組2」後,將右邊的程式碼視窗中的原有內容刪除後,把以下程式碼複製後貼上在程式碼視窗中儲存。

4、再次點擊選單列中的“開發工具”,選擇“巨集”,開啟巨集對話框,“巨集名”選擇剛剛新建的巨集文件,然後點擊“執行”或“單步執行”,等程式運行完成後工作表保護密碼就清除了。 (提示:程式運行時有點卡,如果電腦配置低就選擇單步執行,效果是一樣的)

#VBA程式碼如下:

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?"
