??excel撤銷保護(hù)密碼的方法

??1、打開Excel表格中的Excel選項(xiàng)，選擇自定義，得到如下畫面：

??2、然后在左邊側(cè)框欄中選擇“查看宏”

??之后雙擊或者選擇添加按鈕，則可以看到右邊欄中有了查看宏按鈕，之后點(diǎn)擊右下角的確定。

??3、大家可以在下面這個(gè)窗口處看到箭頭所指的按鈕：

??點(diǎn)擊按鈕，之后彈出窗口：

??4、在宏名處填寫一個(gè)名字(可隨意)，然后點(diǎn)擊創(chuàng)建，彈出以下窗口：

??5、將窗口內(nèi)的內(nèi)容全選后刪除，然后將下面分割線以內(nèi)的內(nèi)容開始復(fù)制粘貼在上面的窗口內(nèi)：

??從橫線下開始復(fù)制

??復(fù)制到橫線以上

??得到情況如下圖表示

??6、關(guān)閉編輯窗口;

??7、依次點(diǎn)擊菜單欄上的工具---宏-----宏,選AllInternalPasswords,運(yùn)行,確定兩次;

??等一會(huì),就會(huì)出現(xiàn)以下對(duì)話框：這就是Excel密碼對(duì)應(yīng)的原始密碼(此密碼和原先設(shè)置的密碼都能打開此文檔。如果是別人的文檔，你又想恢復(fù)密碼設(shè)置，就可以用此密碼進(jìn)行保護(hù)，他就能用他設(shè)置的密碼打開，你可以試試，很有趣的。字母一定要大寫)：

??再點(diǎn)擊確定。Excel的原始密碼就被清除了!!

??8、最后記得關(guān)閉EXCEL文檔時(shí)要保存，否則下回打開，文檔仍舊處于只讀狀態(tài)而無法修改。

??以上就是excel撤銷保護(hù)密碼的方法，希望可以幫助到大家。
