Excel文件密码遗忘？三种专业级恢复方案详解

紧急处理一份受密码保护的Excel文件却无法访问，是典型的办公数据困境。这并非绝境，通过系统性的密码恢复策略，你完全可以重新获得文件的完整编辑权限。以下方法适用于合法访问自有文件。

方法一：利用专业密码恢复工具

对于追求效率的用户，采用成熟的密码恢复软件是最优解。选择一款支持Excel加密算法（如AES）且信誉良好的工具，其核心流程高度自动化。

安装并启动选定的专业软件，导航至“Excel密码恢复”或“工作簿解密”功能模块。导入目标加密文件后，软件通常提供多种攻击模式：针对简单密码的字典攻击，或针对复杂密码的暴力破解。启动恢复进程后，计算时间直接取决于密码强度与硬件性能。

方法二：执行VBA宏代码破解

熟悉Excel开发环境的用户，可通过VBA脚本实施定向破解。此方法本质是编写宏指令，系统化遍历预设字符集。

在目标Excel中按下 Alt + F11 启动VBA编辑器。插入新模块后，完整粘贴以下代码至代码窗口：

Sub PasswordBreaker()
    Dim i As Integer, j As Integer, k As Integer, l As Integer, m As Integer
    Dim n As Integer, o As Integer, p As Integer, q As Integer, r As Integer
    Dim s As Integer, t As Integer, u As Integer, v As Integer, w As Integer
    Dim x As Integer, y As Integer, z As Integer
    Dim myPassword As String
    Dim myWorkbook As Workbook
    Dim myWorksheet As Worksheet

    Set myWorkbook = ActiveWorkbook
    Set myWorksheet = myWorkbook.Worksheets(1)
    On Error Resume Next

    For i = 65 To 90
        For j = 65 To 90
            For k = 65 To 90
                For l = 65 To 90
                    For m = 65 To 90
                        For n = 65 To 90
                            For o = 65 To 90
                                For p = 65 To 90
                                    For q = 65 To 90
                                        For r = 65 To 90
                                            For s = 65 To 90
                                                For t = 65 To 90
                                                    For u = 65 To 90
                                                        For v = 65 To 90
                                                            For w = 65 To 90
                                                                For x = 65 To 90
                                                                    For y = 65 To 90
                                                                        For z = 65 To 90
                                                                            myPassword = Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m) & Chr(n) & Chr(o) & Chr(p) & Chr(q) & Chr(r) & Chr(s) & Chr(t) & Chr(u) & Chr(v) & Chr(w) & Chr(x) & Chr(y) & Chr(z)
                                                                            myWorksheet.Unprotect myPassword
                                                                            If myWorksheet.ProtectContents = False Then
                                                                                MsgBox "Password is " & myPassword
                                                                                Exit Sub
                                                                            End If
                                                                        Next
                                                                    Next
                                                                Next
                                                            Next
                                                        Next
                                                    Next
                                                Next
                                            Next
                                        Next
                                    Next
                                Next
                            Next
                        Next
                    Next
                Next
            Next
        Next
    Next
End Sub

运行此宏将尝试所有由大写字母A-Z构成的18位密码组合。成功破解后，系统将弹出密码提示框。请注意：此脚本仅适用于工作表（Worksheet）保护，对工作簿（Workbook）级加密无效，且密码复杂度会显著影响破解耗时。
