Need code for ms excel
Based on your description, it sounds like you want to create a program in Excel VBA that assigns specific replacements for each digit and then applies these replacements to any four-digit number entered into a cell. Here's a basic implementation of such a program:
Vba code is untested, please backup your file.
Sub ReplaceDigits()
Dim digitMap(0 To 9) As Integer
Dim inputNumber As String
Dim outputNumber As String
Dim i As Integer
' Define the replacements for each digit
digitMap(0) = 2
digitMap(1) = 8
digitMap(2) = 0
digitMap(3) = 1
digitMap(4) = 9
digitMap(5) = 7
digitMap(6) = 4
digitMap(7) = 3
digitMap(8) = 6
digitMap(9) = 5
' Get the input number from the user
inputNumber = InputBox("Enter a four-digit number:")
' Check if the input number is valid
If Len(inputNumber) <> 4 Or Not IsNumeric(inputNumber) Then
MsgBox "Invalid input. Please enter a four-digit number."
Exit Sub
End If
' Replace each digit in the input number using the digitMap
outputNumber = ""
For i = 1 To Len(inputNumber)
outputNumber = outputNumber & CStr(digitMap(CInt(Mid(inputNumber, i, 1))))
Next i
' Output the result
MsgBox "Mapped number: " & outputNumber
End SubTo use this code:
- Press Alt + F11 to open the VBA editor in Excel.
- Go to Insert > Module to insert a new module.
- Copy and paste the code into the module window.
- Close the VBA editor.
- You can now run the ReplaceDigits macro by going to Developer > Macros (if Developer tab is not visible, you can enable it in Excel options) and selecting ReplaceDigits from the list, then click Run.
This code prompts the user to input a four-digit number, applies the digit replacements according to your specifications, and then displays the mapped number in a message box. You can further modify it to apply the replacements to any range of cells or integrate it into your Excel workbook as needed. The text, steps and the code was created with the help of AI.

- Thanks for the reply but my concern is that the decrypted key is 2801 and any 4 digit number entered by the user will be assigned to 2801 as decrypted key and as per that remaining number from 0 to 9 will be decoded if available or leave blank space si that later a strip of decrypted keys could be find manually
If I understand correctly, you want to create a VBA code that allows a user to enter a four-digit number, and the program will decode each digit of that number based on a predefined decryption key (2801 in this case). If a digit is not specified in the decryption key, it will remain unchanged.
Here's a VBA code that implements this functionality:
Vba Code is untested, please backup your file.
Sub DecryptNumber() Dim decryptionKey As String Dim inputNumber As String Dim decryptedNumber As String Dim i As Integer ' Define the decryption key decryptionKey = "2801" ' Get the input number from the user inputNumber = InputBox("Enter a four-digit number:") ' Check if the input number is valid If Len(inputNumber) <> 4 Or Not IsNumeric(inputNumber) Then MsgBox "Invalid input. Please enter a four-digit number." Exit Sub End If ' Decrypt each digit in the input number using the decryption key decryptedNumber = "" For i = 1 To Len(inputNumber) If Mid(decryptionKey, i, 1) <> "" Then decryptedNumber = decryptedNumber & Mid(decryptionKey, i, 1) Else decryptedNumber = decryptedNumber & Mid(inputNumber, i, 1) End If Next i ' Output the decrypted number MsgBox "Decrypted number: " & decryptedNumber End SubThis code prompts the user to enter a four-digit number, decrypts each digit of that number based on the decryption key (2801), and then displays the decrypted number in a message box. If a digit is not specified in the decryption key, it remains unchanged.
- Code is working fine. Thanks
But still there is some problem. That is it shows any 4 digit number to 2801 then combination of other 4 digit number should also automatically assigned accordingly as 2801. For example we have combination of 3 set of 4 digit number for decryption viz, first 8734 , second 3724, third 4425 and now we should assign each digit of the first number i.e. 8734 to 9501 and accordingly shows decrypted key for the remaining set of numbers.
