excel撤銷工作表保護密碼忘記了如何辦

做數據分析的人都知道，原始數據的正確性是非常重要的，常常會因為一個數據的錯誤，導致結果發生很大的偏差。

因此在工作表中將原始數據輸入完成并校對后，為了防止誤操作或是被他人隨意復制，都會選擇將這些數據進行保護。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。當辛辛苦苦做的一份工作表因為忘記密碼再也不能進行修改時，是不是感覺很郁悶呢？

這時該怎么辦呢？重做一份嗎？其實不用這么麻煩，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、點擊菜單欄中的“開發工具”，選擇錄制宏，錄制一個名為“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宏文件）。

2、再次點擊菜單欄中的“開發工具”，選擇“宏”，打開宏對話框，“宏名”選擇剛剛新建的宏文件，然后點擊“編輯”，打開宏（VBA）編輯窗口。

3、在宏（VBA）編輯窗口的左側依次選擇“VBAProject PERSONAL,XLSB”→“模塊”→“模塊2”后，將右側的代碼窗口中的原有內容刪除后，把以下代碼復制后粘貼在代碼窗口中保存。

4、再次點擊菜單欄中的“開發工具”，選擇“宏”，打開宏對話框，“宏名”選擇剛剛新建的宏文件，然后點擊“執行”或“單步執行”，等程序運行完成后工作表保護密碼就清除了。（提示：程序運行時有點卡，如果電腦配置低就選擇單步執行，效果是一樣的）

VBA代碼如下：

Public Sub 工作表保護密碼破解()

Const HUANHANG As String = vbNewLine & vbNewLine

Const MINGCHEN As String = "清除工作表保護密碼"

Const JINGGAO As String = "該工作簿中的工作表密碼保護已全部清除!!" & HUANHANG & "請記得另保存" _

& HUANHANG & "注意：不要用在不當地方，要尊重他人的勞動成果！"

Const TISHI1 As String = "該文件工作表中沒有加密"

Const TISHI2 As String = "該文件工作表中沒有加密2"

Const KSPJ As String = "解密需花費一定時間,請耐心等候!" & HUANHANG & "按確定開始清除!"

Const FXMM1 As String = "密碼重新組合為:" & HUANHANG & "$$" & HUANHANG & _

"如果該文件工作表有不同密碼,將搜索下一組密碼并修改清除"

Const FXMM2 As String = "密碼重新組合為:" & HUANHANG & "$$" & HUANHANG & _

"如果該文件工作表有不同密碼,將搜索下一組密碼并解除"

Const MSGONLYONE As String = "確保為唯一的?"
