Excel中2007版進(jìn)行撤銷(xiāo)保護(hù)密碼的操作技巧
工作中，有時(shí)會(huì)出現(xiàn)這樣的情況，用Excel編制的單元格中設(shè)置了公式、函數(shù)等，為了防止其他人修改。今天，學(xué)習(xí)啦小編就教大家在Excel中2007版進(jìn)行撤銷(xiāo)保護(hù)密碼的操作技巧。
Excel中2007版進(jìn)行撤銷(xiāo)保護(hù)密碼的操作步驟
1、打開(kāi)Excel表格中的Excel選項(xiàng)，選擇自定義，得到如下畫(huà)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。

點(diǎn)擊按鈕，之后彈出窗口：
4、在宏名處填寫(xiě)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?xún)?nèi)的內(nèi)容開(kāi)始復(fù)制粘貼在上面的窗口內(nèi)：
從橫線下開(kāi)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(kāi)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(kāi)，你可以試試，很有趣的。字母一定要大寫(xiě))：
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(kāi)，文檔仍舊處于只讀狀態(tài)而無(wú)法修改。
