Ⅱ 如何解锁excel中的密码忘了怎么办

Excel保护密码若是忘记，可通过以下步骤进行解锁：

所需材料：解压软件（这里用的WINRAR）、Excel2007演示。

一、下图中这个表格文件被保存，双击表格内单元格内会弹出该表格为只读，那么开始破解该表格。

注意事项：

1、第五步查找的内容“sheetPro”中，“P”必须是大写，其他字母必须全部为小写，否则找不到。

2、第六步选中的是“sheetPro”所在尖括号内的全部内容，包含尖括号。

3、若是使用能够在压缩包内修改的压缩软件，第三步可跳过，直接在压缩包内进行修改。

Ⅲ Excel文件忘记密码怎么办

1、找到被密码的保护Excel表格文档，鼠标右键点击该文档，在属性中将忘记密码的Excel文件名称后缀由。xlsx格式改为。rar格式。
2、打开电脑的360压缩，用360压缩打开忘记密码的Excel文件，然后在360压缩的菜单栏中将此文件还原，然后重新压缩成sheet1.xml格式。

Ⅳ Excel的保护密码忘记了怎么办，急用

有两种方法可以解决：

方法1：使用密码破解程序破解。以下为具体方法：

1打开文件

2工具---宏----录制新宏---输入名字如:aa

3停止录制(这样得到一个空宏)

4工具---宏----宏,选aa,点编辑按钮

5删除窗口中的所有字符(只有几个),替换为下面的内容:(复制吧)

6关闭编辑窗口

7工具---宏-----宏,选AllInternalPasswords,运行,确定两次,等2分钟,再确定.OK,没有密码了!!

内容如下：

再用该密码给保护，原来使用者的密码同样能打开。

方法2：使用压缩包解决。

• 将文件后缀名改为RAR。

• 打开压缩包文件，找到一个xml文件，用文本方式打开。

• 打开之后，找到代码pssword 语句，将该句删掉。

• 再将后缀名改为xls，再打开就没有密码了。

Ⅳ excel打开密码忘记了怎么办

1.开启excel文件点击撤销工作簿保护时忘记密码的情况,
2.这时就可以右键文件,开启右键菜单列表,
3.点击重命名把文件后缀改成rar,
4.改成完rar使用压缩应用打开这个rar文件,
5.然后打开xl目录下的worksheets文件夹,
