1、Excel 中如何破解“撤銷工作表保護(hù)密碼”并獲取原始密碼一、保護(hù)工作表的方法1 、 全選定工作表右擊 設(shè)置單元格格式 找到保護(hù)將鎖定和 隱藏 兩個(gè)的勾去掉；2、將要保護(hù)的工作表單元格選定右擊設(shè)置單元格格式 找到保護(hù)將 鎖定 和 隱藏兩個(gè)的勾打上；3 、 點(diǎn)菜單欄的工具 中的保護(hù)里的 保護(hù)工作表將保護(hù)工作表及鎖定的單元內(nèi)容打上勾，下選允許此工作表的所有用戶選定未鎖定的單元格打上勾二、Excel 工作表保護(hù)密碼破解方法（如果Excel 文件的打開密碼忘記了，且密碼是6 位數(shù)以內(nèi)的數(shù)字，可用以下步驟解開（關(guān)掉所有程序，為了速度）：新開一Excel ，同時(shí)按Alt 和 F11 ，進(jìn)入 VBA 界面，

2、點(diǎn)菜單上的插入，模塊，在新出來的窗口粘貼一下代碼：然后在此界面直接按F5 運(yùn)行此宏，選擇文件，等啊等（看密碼長度了）1 、打開您需要破解保護(hù)密碼的Excel 文件；2、依次點(diǎn)擊菜單欄上的工具- 宏 錄制新宏，輸入宏名字如:aa；3、停止錄制（這樣得到一個(gè)空宏）；4、依次點(diǎn)擊菜單欄上的工具 -宏-宏選aa,點(diǎn)編輯按鈕；5、刪除窗口中的所有字符（只有幾個(gè)）,替換為下面的內(nèi)容；從橫線下開始復(fù)制Option ExplicitPublic Sub AllInternalPasswords()' Breaks worksheet and workbook structure passwords.
