excel忘记密码是无法找回的，但可以删除加密数据，来解锁excel文件，具体操作如下：

1、首先选中被加密的excel文件，按F2键把文件后缀名改为rar。

2、然后双击打开该压缩文件，选择打开XL文件夹。

3、接着打开worksheets文件夹，将sheet1.xml文件拖到桌面。

4、右键该文件选择使用记事本打开，按Ctrl+F键查找protection。

5、删除该词所在尖括号内的全部内容并保存，再将该文件拖回压缩包。

6、最后在弹窗中点击确定按钮，将压缩文件后缀名重新改为XLSX即可。

只要知道密码特征，根据组合遍历尝试，一般情况下是可以解密的。

举例说明。

将文件sample保存为带密码的文件，密码设置为“123”。如图：

第二步：创建新文档。

第三步：插入模块，输入以下代码。

Sub crack()

Dim i As Long

Dim FileName As String

i = 0

FileName = Application.GetOpenFilename("Excel文件(*.xls & *.xlsx),*.xls;*.xlsx", , "VBA破解")

FileName = Right(FileName, Len(FileName) - InStrRev(FileName, "\"))

Application.ScreenUpdating = False

line2: On Error GoTo line1

Workbooks.Open FileName, , True, , i

MsgBox "Password is " & i

Exit Sub

line1: i = i + 1

Resume line2

Application.ScreenUpdating = True

End Sub

如图：

第四步：运行宏。如图：

第五步：按提示打开指定的文件。运行后结果如图：

说明：1、这段程序仅适用于纯数字的密码；

          2、如果知道密码的基本特征，对上述代码进行适当的修改，基本也可以实现。

设置的什么密码？如果是工作表保护密码的话试试这个：
打开文件-----工具---宏----录制新宏------输入名字如:123-----停止录制(这样得到一个空宏)工具---宏----宏------选123,----点编辑按钮---删除窗口中的所有字符替换为下面的内容（呵呵，代码不是我写的，感谢写这段代码的人，非常好用）为免输错，你可以直接复制：

哈哈没有密码了

付费内容限时免费查看回答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。
