步驟7：關(guān)閉編輯窗口;
步驟8：依次點(diǎn)擊菜單欄上的工具---宏-----宏,選AllInternalPasswords,運(yùn)行,確定兩次;
步驟9：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)：
步驟10：再點(diǎn)擊確定。Excel的原始密碼就被清除了!!
