2. excel有密码保护怎么破解

一、整个Excel表被锁定的解锁方法：

首先打开设置了工作表保护的表格，点击工具栏的查阅，再点击撤销工作表保护，输入密码即可解锁。

二、解锁Excel表中的单元格

打开Excel表，全选，右击鼠标选择设置单元格格式，选择保护，把“锁定”前面的勾去掉，点击确定即可

3. excel的保护密码怎么破解不了

1、你打开的文件是不是在excel里进行过加密？

2、将这个文件拷到别的电脑上试试看能不能打开，如果可以，就另存为另一个文件回来尝试打开。

3、是不是在ntfs下进行过文件加密，如果是就需要加密人在它的登录状态下来打开。

4. excel的保护密码忘了怎么办

excel中取消密码保护的步骤分为以下三步：

　　1、在excel中点击“打开”按钮输入密码，打开加密后的文件。

　　2、在弹出的页面中选择“保护工作簿”一栏。

　　3、填入密码后点击“删除密码”即可。

5. excel的保护密码怎么破解啊

1，打开一个有工作表保护密码的Excel表格，双击可看到因为密码保护无法修改，点击“确定”，关闭表格。

2，点击表格的文件名，更改后缀xlsx为rar，按回车键后提示命名风险，点击“是”。双击这个文件，会被用解压软件打开。

3，点击“xl”，打开“worksheets”，将“sheet1.xml”文件拖拽到桌面上并点击右键，选择“打开方式”，点击“记事本”。

4，按Ctrl+F查找，输入protection，点击“查找下一个”，将<sheetprotection到=“1”/>这段代码删除。

5，点击“文件”，选择“保存”，把修改后的sheet1.xml文件拖拽回压缩工具中。

6，点击“替换”，关闭压缩工具，把示例文件的后缀改回xlsx即可。

6. excel 密码保护可以破解吗

1.

切换至【审阅】选项卡；

2.

单击【撤销工作表保护】；

3.

连续输入两次密码即可！这样就可以将excel表格的密码保护可以解除完成了。

7. excel被密码保护,破解

如果你只有打开密码，且密码是7位数以内的数字，可用以下步骤解开：

新开一Excel，打开，记住文件路径，取消。然后把你待解密文件copy到这一路径，改名为1.xls。然后回到Excel窗口，同时按键盘的Alt和F11，右键点左上窗口中的VBAProject，插入，模块，在右边新出来的窗口粘贴一下代码

Subcrack()

DimiAsLong

i=1

line2:

OnErrorGoToline1

DoWhileTrue

Workbooks.Open"1.xls",,,,i

Workbooks("1.xls").Close0

MsgBox"Passwordis"&i

ExitSub

Loop

line1:

i=i+1

Resumeline2

EndSub

然后运行此宏（回到Excel窗口，工具，宏，宏，DefineHyperlink，运行）

如果有字母，稍微复杂些，道理是一样的。太长的密码，基本解不开了。

若果还有读写密码，且与打开密码一样，将Workbooks.Open"1.xls",,,,i改为Workbooks.Open"1.xls",,,,i,i

8. excel保护密码忘了怎么解

1、先找到有工作表保护密码的Excel表格，然后将忘记密码的Excel文件名称后缀由 .xlsx改为 .rar，如果有提示可以忽略，一般不会造成什么影响。

　2、用压缩文件打开忘记密码的Excel文件，然后按以下步骤进行操作：xl——worksheets——sheet1.xml（这里是将sheet1工作表设置了保护密码，可根据实际情况选择相应文件名）。

　3、从压缩文件里面找到sheet1.xml文件，然后拖拽至一个方便找到的位置（因为我们要对其要进行修改） 。然后将sheet1.xml文件右击选择用记事本打开方式打开。

　4、然后搜索，“protection”，把从这一段代码，全部删除掉。

　　　5、然后再把修改后的sheet1.xml文件，选择拖拽到压缩的工作薄中，选择替换掉即可，点击确定。

　6、最后一步，和第一步相反，把文件名称后缀，由“演示表格.rar”重新更改“演示表格.xlsx”。最后打开Excel表格，你会惊喜地发现是不是保护密码都取消了吧。

9. excel 破解保护密码

如果Excel文件的打开密码忘记了，且密码是6位数以内的数字，可用以下步骤解开（关掉所有程序，为了速度）：

新开一Excel，同时按Alt和F11，进入VBA界面，点菜单上的插入，模块，在新出来的窗口粘贴一下代码：

Sub crack()Dim i As LongDim FileName As Stringi = 0FileName = Application.GetOpenFilename("Excel文件（*.xls & *.xlsx）,*.xls;*.xlsx", , "VBA破解")FileName = Right(FileName, Len(FileName) - InStrRev(FileName, "\"))Application.ScreenUpdating = Falseline2: On Error GoTo line1Workbooks.Open FileName, , True, , iMsgBox "Password is " & iExit Subline1: i = i + 1Resume line2Application.ScreenUpdating = TrueEnd Sub然后在此界面直接按F5运行此宏，选择文件，等啊等（看密码长度了）
