execl密码忘了咋办

如果忘记了 Excel 文档的密码，可以尝试以下方法：

1. 使用 VBA 代码解锁：打开 Excel 文档，按 ALT + F11 进入 VBA 编辑器，插入下面的代码：

   Sub PasswordBreaker()
   'Breaks worksheet password protection.
   Dim i As Integer, j As Integer, k As Integer
   Dim l As Integer, m As Integer, n As Integer
   Dim i1 As Integer, i2 As Integer, i3 As Integer
   Dim i4 As Integer, i5 As Integer, i6 As Integer
   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 i1 = 65 To 66
   For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
   For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126

   ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
   Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
   Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
   If ActiveSheet.ProtectContents = False Then
       MsgBox "One usable password is " & Chr(i) & Chr(j) & _
       Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
       Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
       Exit Sub
   End If
   Next: Next: Next: Next: Next: Next
   Next: Next: Next: Next: Next: Next
   End Sub

然后按 F5 运行代码，稍等一会儿，Excel 就会自动解锁。如果出现提示框，显示已找到可用的密码，则按照提示输入即可。

2. 使用第三方解锁工具：可以使用一些第三方的 Excel 解锁工具，例如 PassFab for Excel、Excel Password Recovery 等，但是需要注意工具的安全性，避免下载到恶意软件。

请注意，这些方法仅适用于解锁 Excel 文档的密码，如果您忘记了打开 Excel 文档的密码，则无法使用这些方法。
