今天得到一個任務，是破解一個excel工作表的保護密碼。我覺的網上的教程都挺好的，主要一點是注意excel中沒有工具這一欄，需要自己去尋找出相關項。
用到的教程如下：
添加相關工具項
點擊excel最左上角的標誌（花）——最下方的excel選項——自定義——選擇開發工具項——添加需要的工具項如宏安全性、查看宏、錄製宏、visual basic——點擊確定。
可以看到需要的工具項都已經在左上角出現了。
設置好工具欄宏，需要啓用宏。
然後就下面就是按照教程來一步步操作即可。
1新建宏 錄製新宏隨便輸入個名字如hong 點擊“確定”按鈕
2點擊“停止錄製”按鈕或從菜單“停止錄製”宏
3選擇剛纔所建的宏然後點擊“編輯”按鈕，會彈出代碼編寫窗口
4填寫代碼將下面的代碼全部複製必替換原來的字符，填寫完畢後關閉該窗口
//這裏十分感謝原作者，因爲經實踐，確實好用。
