Excel trick for this task

Question

I've got a spreadsheet in excel with this rows:

       COLUMN
Value1.Value2.Value3
Value4.Value5.Value6
Value7.Value8.Value9

In another spreadsheet I've got a simple list with names:

   COLUMN
    Name1
    Name2
    Name3

And,of course, this list is huge :).

So need to have the following spreasdsheet at the end:

       COLUMN

Value1.Name1.Value2.Value3
Value4.Name1.Value5.Value6
Value7.Name1.Value8.Value9
Value1.Name2.Value2.Value3
Value4.Name2.Value5.Value6
Value7.Name2.Value8.Value9
Value1.Name3.Value2.Value3
Value4.Name4.Value5.Value6
Value7.Name4.Value8.Value9

I have to concatenate the names on the list with all the values on spreadsheet replicating them for ALL the names.

Is there a way of doing this process automatically? The manual process would take hours to be done and I think there's a smarter way of doing that although I don't know it! :)

Thanks in advance for your help.

Answer 1

There is always a "." between the values.

Try this code. Using arrays would be much faster for huge list of names/values:

Sub test()
    Dim arrVal As Variant
    Dim arrNames As Variant
    Dim arrRes As Variant
    Dim v, n, k As Long

    'change Sheet1 to suit
    With ThisWorkbook.Worksheets("Sheet1")
        'change A1:A3 to values address
        arrVal = .Range("A1:A3")
        'change B1:B3 to names address
        arrNames = .Range("B1:B3")

        ReDim arrRes(1 To UBound(arrVal) * UBound(arrNames), 1 To 1)
        k = 1
        For Each v In arrVal
            For Each n In arrNames
                arrRes(k, 1) = Left(v, InStr(1, v, ".")) & n & Mid(v, InStr(1, v, "."))
                k = k + 1
            Next
        Next v

        'change "c1" to start cell where to put new values
        .Range("C1").Resize(UBound(arrRes, 1)) = arrRes
    End With
End Sub

Note: If you don't know exact addresses of "values" and "name" ranges, change this part

'change A1:A3 to values address
arrVal = .Range("A1:A3")
'change B1:B3 to names address
arrNames = .Range("B1:B3")

to

'change A1:A to "values" address
arrVal = .Range("A1:A" & .Cells(.Rows.Count, "A").End(xlUp).Row)
'change B1:B to "names" address
arrNames = .Range("B1:B" & .Cells(.Rows.Count, "B").End(xlUp).Row)

In that case "values" and "name" ranges starts from A1 and B1 accordingly and ends in the last non empty row in coumns A and B accordingly.

Result:

Answer 2

And it is a good challenge to do it with formulas: :)

With this array formula in D1 and then copy down

=INDEX(LEFT($A$1:$A$4;FIND(".";$A$1:$A$4))&TRANSPOSE($C$1:$C$3)&RIGHT($A$1:$A$4;LEN($A$1:$A$4)-FIND(".";$A$1:$A$4)+1);1+INT((ROWS($D$1:D1)-1)/ROWS($C$1:$C$3));1+MOD(ROWS($D$1:D1)-1;ROWS($C$1:$C$3)))

Depending on your regional settings you may need to replace field separator ";" by ","

Answer 3

I think that could work.

    Const FIRST_TALBE = 4
    Const SECOND_TABLE = 2

    Sub makeTheJob()
        For i = 1 To lastRow
            l = Split(Cells(i, FIRST_TABLE), ".")
            newvalue = l(0) & "." & Cells(i, SECOND_TABLE) & "." & l(1) & "." & l(2)
            Debug.Print newvalue
        Next i
    End Sub
