I. Excel File Password Recovery

Excel is one of the Office software programs we commonly use in our daily work. Sometimes we set passwords to protect important Excel files. But what should we do when we forget our password? In fact, there are many ways to help us recover the password for an Excel file.

1. Using Excel's built-in password recovery function: Excel 2010 and later versions have a built-in password recovery function. We can use it by following these steps:

   • Open the Excel file where you forgot your password, click the "File" menu, and select the "Information" tab.
   • On the Messages tab, click the Protect Workbook button and select Encrypt with Password.
   • In the Encrypted Document dialog box that pops up, enter the correct password and click the OK button.
   • Reopen the Excel file where you forgot your password, click the "File" menu, and select the "Information" tab.
   • On the Messages tab, click the Protect Workbook button and select Encrypt with Password.
   • In the Encrypted Document dialog box that pops up, enter the wrong password and click the OK button.
   • Excel will pop up a prompt telling you that the password is incorrect. At this point, click the "Help" button and select "Recover password with VBA".
   • In the VBA editor that pops up, copy and paste the following code into the module: Sub CrackPassword() Dim wb As Workbook Dim i As Integer Dim j As Integer Dim k As Integer Dim l As Integer Dim m As Integer Dim n As Integer Dim or As Integer Dim p As Integer Dim q As Integer Dim r As Integer Dim s As Integer Dim t As Integer Dim u As Integer Dim v As Integer Dim w As Integer Dim x As Integer Dim and As Integer Dim z As Integer Dim password As String Set wb = ActiveWorkbook 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 password = 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) On Error Resume Next wb.Unprotect password If Err. Number = 0 Then MsgBox "The password is:" & password Exit under End If Err.Clear End If Next Next Next Next Next Next Next Next Next Next Next Next Next Next Next Next Next End Sub
   • Press the "F5" key to run the code, and Excel will automatically try to crack the password. This process may take some time, depending on the complexity of the password.
   • If the password is successfully cracked, Excel will pop up a prompt telling you what the password is. If the password cannot be cracked, Excel will pop up a message telling you that it cannot be cracked.
