Any possible VBA code to double and sequentially number names in excel? - excel

Question

Is there any possible way to take a list of items or names, such as:
Apples
Oranges
Grapes
Watermelons
And have Excel double that information and sequentially number it, like this:
Apples1
Apples2
Oranges1
Oranges2
Grapes1
Grapes2
Watermelons1
Watermelons2
I know a little bit of VBA but I can't wrap my head around how I would even start this.

Answer 1

You can specify where you want to read, and where you want to start write and how many times you want to repeat!
Just change the code:
Sub DoRepeat()
Dim repeatTimes As Integer
Dim rng As Range, cell As Range
repeatTimes = 2
Set cellsToRead = Range("A1:A3")
Set cellStartToWrite = Range("B1")
For Each cell In cellsToRead
For i = 1 To repeatTimes
cellStartToWrite.Value = cell.Value + CStr(i)
Set cellStartToWrite = Cells(cellStartToWrite.Row + 1, cellStartToWrite.Column)
Next
Next cell
End Sub

As it seems it is required to have a more dynamic approach, try this out. The DoubleNames function will return the names duplicated N number of times specified in the DuplicateCount parameter. It will return a Collection, which you can easily dump to a range if need be.
Public Function DoubleNames(ByVal DataRange As Excel.Range, DuplicateCount As Long) As Collection
Set DoubleNames = New Collection
Dim dict As Object: Set dict = CreateObject("Scripting.Dictionary")
Dim i As Long
Dim DataItem As Excel.Range
Set DataRange = DataRange.SpecialCells(xlCellTypeConstants)
For Each DataItem In DataRange
For i = 1 To DuplicateCount
If Not dict.Exists(DataItem.Value) Then
DoubleNames.Add (DataItem.Value & "1")
dict.Add DataItem.Value, 1
Else
dict(DataItem.Value) = dict(DataItem.Value) + 1
DoubleNames.Add (DataItem.Value & dict(DataItem.Value))
End If
Next
Next
End Function
Sub ExampleUsage()
Dim item As Variant
Dim rng As Range: Set rng = ThisWorkbook.Sheets("Sheet1").Range("A1:A5")
For Each item In DoubleNames(rng, 5)
Debug.Print item
Next
End Sub

Answer 3

I would start by writing a general function that outputs the names (passed as a variant array) a given number of times:
Public Sub OutputNames(ByVal TimesToOutput As Integer, ByRef names() As Variant)
Dim nameIndex As Integer, outputIndex As Integer
For nameIndex = LBound(names) To UBound(names)
For outputIndex = 1 To TimesToOutput
Debug.Print names(nameIndex) & outputIndex
Next outputIndex
Next nameIndex
End Sub
Here you can see the sub that tests this:
Public Sub testOutputNames()
Dim names() As Variant
names = Array("Apples", "Oranges", "Grapes", "Watermelons")
OutputNames 2, names
End Sub
which gives you this output:
Apples1
Apples2
Oranges1
Oranges2
Grapes1
Grapes2
Watermelons1
Watermelons2
