Excel密码保护解除指南：轻松移除工作表或工作簿密码

为什么需要去除Excel密码保护？

在日常工作中，我们经常收到或创建带有密码保护的Excel文件。无论是工作表保护（限制编辑）还是工作簿打开密码（限制访问），一旦遗忘密码或需要修改数据，就会成为障碍。本文将提供几种安全、有效的方法来移除这些保护。

方法一：使用VBA代码移除工作表保护密码

适用于Excel 2010及更高版本。此方法通过暴力破解密码，但通常能快速处理简单密码。

1. 打开Excel文件，按 Alt + F11 打开VBA编辑器。
2. 在菜单栏选择 插入 -> 模块。
3. 将以下代码粘贴到模块窗口中：

   Sub RemoveSheetProtection()
       Dim i As Integer, j As Integer, k As Integer, l As Integer, m As Integer, n As Integer
       Dim o As Integer, p As Integer, q As Integer, r As Integer, s As Integer, t As Integer
       Dim u As Integer, v As Integer, w As Integer, x As Integer, y As Integer, z As Integer
       Dim a As String, b As String, c As String, d As String, e As String, f As String
       Dim g As String, h As String, i2 As String, j2 As String, k2 As String, l2 As String
       Dim m2 As String, n2 As String, o2 As String, p2 As String, q2 As String, r2 As String
       Dim s2 As String, t2 As String, u2 As String, v2 As String, w2 As String, x2 As String
       Dim y2 As String, z2 As String
       On Error Resume Next
       For i = 65 To 66: For j = 65 To 66: For k = 65 To 66: For l = 65 To 66: For m = 65 To 66: For n = 65 To 66
           For o = 65 To 66: For p = 65 To 66: For q = 65 To 66: For r = 65 To 66: For s = 65 To 66: For t = 65 To 66
               For u = 65 To 66: For v = 65 To 66: For w = 65 To 66: For x = 65 To 66: For y = 65 To 66: For z = 65 To 66
                   a = Chr(i): b = Chr(j): c = Chr(k): d = Chr(l): e = Chr(m): f = Chr(n)
                   g = Chr(o): h = Chr(p): i2 = Chr(q): j2 = Chr(r): k2 = Chr(s): l2 = Chr(t)
                   m2 = Chr(u): n2 = Chr(v): o2 = Chr(w): p2 = Chr(x): q2 = Chr(y): r2 = Chr(z)
                   ActiveSheet.Unprotect a & b & c & d & e & f & g & h & i2 & j2 & k2 & l2 & m2 & n2 & o2 & p2 & q2 & r2
                   If ActiveSheet.ProtectContents = False Then
                       MsgBox "密码已移除！"
                       Exit Sub
                   End If
               Next: Next: Next: Next: Next: Next: Next: Next: Next: Next: Next: Next
           Next: Next: Next: Next: Next: Next
       Next: Next: Next: Next: Next: Next
   End Sub

4. 按 F5 运行代码。如果密码简单，程序会很快找到并移除保护。
5. 如果运行时间较长，可按 Ctrl + Break 中断。

方法二：更改文件扩展名并编辑XML

适用于Excel 2007及以上版本（.xlsx格式）。此方法通过直接修改文件内部的XML来移除保护。

1. 复制一份Excel文件，将扩展名改为 .zip。
2. 解压压缩包，找到 xl/worksheets/sheet1.xml（每个工作表对应一个）。
3. 用记事本打开该XML文件，查找 <sheetProtection 标签。
4. 删除整行包含 <sheetProtection 的内容，保存文件。
5. 重新打包所有文件，将扩展名改回 .xlsx。打开时密码已移除。

方法三：使用第三方工具

如果上述方法无效或文件有工作簿打开密码，可以借助专业软件：

• PassFab for Excel：支持找回或移除打开密码和限制密码。
• Excel Password Recovery Lastic：支持暴力破解和字典攻击。
• Online Service：如 LostMyPass，上传文件在线解密（注意隐私风险）。

使用工具时，请确保来源可靠，避免恶意软件。

注意事项

• 请确认您有权解除密码保护。未经授权破解他人文件可能违法。
• 建议对重要文件备份后再操作。
• 如果文件中包含宏或复杂结构，某些方法可能导致文件损坏。

掌握这些技巧，您将不再为Excel密码烦恼。选择最适合您情况的方法，快速恢复对数据的控制。
