網上有不少這個代碼，但不少朋友並不太瞭解如何運用在此作了一些整理，但願對你們有所幫助！

注：不少時候會由於忘記密碼丟失重要EXCEL文件而煩惱，這份代碼就能幫你找回，僅僅出之這個初衷，如由於這個代碼讓你感到不安全，那請增強電腦文件的密保，如用在不當的地方，後果自負！

方法/步驟

 

1. 1

   一、新建一個EXCEL文件「BOOK1」，在工具欄空白位置，任意右擊，選擇Visual Basic項，彈出Visual Basic工具欄：
2. 2

   二、在Visual Basic工具欄中，點擊「錄製」按鈕，彈出「錄製新宏」對話框，選擇「我的宏工做簿」：
3. 3

   三、選擇「我的宏工做簿」後按肯定，彈出以下「暫停」按鈕，點擊中止：
4. 4

   四、在Visual Basic工具欄中，點擊「編輯」按鈕：
5. 5

   五、點擊「編輯」按鈕後，彈出以下圖的編輯界面：
         找到「VBAProject（PERSONAL.XLS）－模塊－模塊1（也多是模塊N-其餘數字）」
         雙擊模塊1－將右邊代碼內容清空  
6. 6

   六、複製「工做保護密碼破解」代碼到右邊框中，點保存，而後關閉「BOOK1」
7. 7

   七、運行須要解密的「EXCEL文件」，在Visual Basic工具欄中，點擊「運行」按鈕
8. 8

   八、點擊「運行」按鈕後，彈出「宏」對話框，
        點擊運行「PERSONAL.XLS!工做保護密碼破解」這個宏
9. 9

   九、運行「PERSONAL.XLS!工做保護密碼破解」這個宏後，
        以下圖示意就能夠 解除工做表的密碼保護了

    （這個圖，若是工做表中有多組不一樣密碼，
       每解開一組，就會提示一次，也就說可能會出現幾回）
