2. 怎樣取消EXCEL表格的密碼保護

如果可以用只讀方式打開這個文件，那麼只要打開後「另存為」一個就行了，另存後的文件就沒有密碼了。

3. 怎麼解除excel密碼保護

打開文檔後，通過文件菜單中「另存為」，將文檔存為rtf格式。保存好文件後，先關掉文檔再打開另存的文件，選擇工具欄中的「解除文檔保護」命令，不用填寫密碼就可以解除此文件的「文檔保護功能」，而且任何信息都不會丟失。用Office Password Remover這個軟體可以打開。
使用方法：
首先運行解壓好的OPRemove.exe 這個程式，打開程式後能看到中間文本框後面有個類似目錄的按鈕。
選擇後出現下圖的畫面，點擊移除密碼。
呆幾秒鍾後便出現「該文件已被成功破解」，點確定即可，這時候就大功告成了。在這里要注意的是，破解後的文章名字會有點變化，加了「DEMO」這四個字母，翻譯過來就是示範的意思，不必在意，重命名去掉就能了。

4. 怎樣破解Excel工作表保護密碼

它可以在很短的時間內破解Word和Excel文檔的密碼，經過測試最多不超過5秒。使用本軟體時需要連接到Internet，因為要給該軟體的伺服器發送數據並解密。不過大家可以放心，本軟體不會泄露任何個人隱私。

使用方法：

首先運行解壓好的OPRemove.exe 這個程序，打開程序後可以看到中間文本框後面有個類似文件夾的按鈕。

點擊它瀏覽打開要破解的文檔。

呆幾秒鍾後便出現「該文檔已經被成功破解」，點確定即可，這時候就大功告成了。

在這里要注意的是，破解後的文章名字會有點變化，加了「DEMO」這四個字母，翻譯過來就是示範的意思，不必在意，重命名去掉就可以了。

另外，為了防止別人用該軟體，也可以給它設置密碼，打開軟體後，點文件 — 設置訪問密碼，輸兩遍就OK了。下次運行時就出現提示要求輸入運行程序的密碼。
