2. Excel怎么破解密码

在打开这个Excel表格文件时提示要输入密码，下面我们来分享怎么取消这个密码。

输入文件的密码，打开这个Excel表格文件，然后点击菜单栏中的“文件”，点击文件后就打开excel设置页面，在“保护工作薄”的位置可以看到加密的说明，点击“保护工作薄”，之后在打开的菜单中选择“用密码进行加密”，点击“用密码进行加密”后，打开“加密文档”的对话框，删除密码下面输入框中的密码，然后点击下面的确定，这样就删除了Excel表格文件的打开密码。

回到Excel表格设置页面中，可以看到在“保护工作薄”下面的加密提示信息已经没有了，表示取消密码成功，

3. excel密码破解方法

Excel加密文件拒绝访问的解决办法如下

对被加密的文件点击鼠标右键，选择“属性”，在“常规”选项卡下面选择“高级”，其中有一项“加密内容以便保护数据”后面点击“详细信息”，其中有一栏为“用户名”，下面的那个信息就是列出了那个文件是被哪个用户加的密码。

假如你这个密码文件是被USER用户加的密，那麼你用USER这个用户登入电脑，再把加密取消，也就是说把“加密内容以便保护数据”前面的勾去掉就可以了。

4. excel设置密码了能破解吗

制表人在表格编辑中，如果发现表格被锁定的，是因为表格创建人设置了表格保护密码，对表格内容进行保护，禁止其他用户修改表格内容，因此，制表人要解锁的，需要向创建人索取解除保护密码即可。

5. excel设置了密码怎样破解呢

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
