Binary Combination :

If You want to make binary Digit Combination . You can use this  Macro :-

Sub MakeCobmination()

Application.ScreenUpdating = False
    Dim t As Double
    Dim Digit As Double
    Dim SS As Double
    Dim j As Double
    Combination = InputBox("Enter Digit ")
    SS = 2 ^ Combination
   
    If Val(Combination) > 20 Then
        MsgBox "you Can give till 20 ", vbInformation
        Exit Sub
    End If
    t = 1
    n = 1
    lp = 1
    j = 1
    Cells.ClearContents
   
For lp = 1 To Combination
            For n = 1 To SS / lp * 2
            For i = 1 To lp
            Cells(j, lp).Value = 0
            j = j + 1
        Next

                For i = 1 To lp
                        Cells(j, lp).Value = 1
                        j = j + 1
                Next

Cells(j, lp).Select
    If ActiveCell.Row >= SS + 1 Then Exit For
    Next
j = 1
Next
                Range("A" & Range("A65536").End(xlUp).Row + 1).Resize(ActiveSheet.UsedRange.Rows.Count, ActiveSheet.Columns.Count).ClearContents
                  C = ActiveSheet.UsedRange.Columns.Count
                  R = ActiveSheet.UsedRange.Rows.Count
               
                For H = 1 To R
                    For M = 1 To C
                    st = st & Cells(H, M).Value
                    Next
                    Cells(H, C + 1).Value = "'" & st
                    st = ""
                Next
Range("A1").Resize(ActiveSheet.UsedRange.Rows.Count, ActiveSheet.UsedRange.Columns.Count - 1).Columns.Delete
Application.ScreenUpdating = True
End Sub
