In today's digital age, the security of files becomes increasingly important. However, sometimes we may forget the password of a file or the password is accidentally changed. What should we do then? Don't worry. Today I will share with you some practical experiences and techniques about password recovery of Excel, Word, PDF, PPT, RAR, ZIP, 7z and other files, so that you can easily retrieve the lost file password.
I. Excel File Password Recovery
Excel is one of the commonly used office software in our daily work. A lot of important data are saved in Excel files. If you forget the password of an Excel file, we can recover it through the following methods:
```vb Sub CrackPassword() Dim FileName As String Dim Password As String 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 o 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 y As Integer Dim z As Integer
FileName = "C:\Users\Administrator\Desktop\example.xlsx"
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
Workbooks.Open FileName,,, Password
If Err.Number = 0 Then
MsgBox "Password is: " & Password
Exit Sub
End If
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
End Sub ```
This code will try all possible password combinations until the correct password is found. It should be noted that this method requires a certain programming foundation and the cracking process may be time-consuming.
II. Word File Password Recovery
Word is also one of the commonly used office software. A lot of important documents are saved in Word files. If you forget the password of a Word file, we can recover it through the following methods:
```vb Sub CrackPassword() Dim FileName As String Dim Password As String 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 o 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 y As Integer Dim z As Integer
FileName = "C:\Users\Administrator\Desktop\example.docx"
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
Documents.Open FileName,,, Password
If Err.Number = 0 Then
MsgBox "Password is: " & Password
Exit Sub
End If
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
Next
End Sub ```
The principle of this code is similar to the password recovery code of Excel files. It also tries all possible password combinations to find the correct password.

PPT is a software commonly used when making presentation slides. A lot of important presentation slides are saved in PPT format. If you forget the password of a PPT file, we can recover it through the following methods:
```vb Sub CrackPassword() Dim FileName As String Dim Password As String 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 o 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 y As Integer Dim z As Integer
FileName = "C:\Users\Administrator\Desktop\example.pptx"
For i = 65 To 90
For j = 65 To 90
For k = 65 To 90
For l = 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)
