I have a set of data that looks like this.

**Source structure**

But I would like to duplicate the project columns into individual rows on another sheet. In this situation Each single row in the source sheet would generate four rows in the target sheet since there are four projects.

Here’s a picture of the desired target data structure.

**Target data structure**

This data will be changing regularly and new entries will be added to the bottom of the source. I’ve figured out how to loop over a range of data but can’t figure out how to select individual cells for writing on the next sheet. I’m a VBA newbie, so any help would be appreciated.

I’ve got two posts, with usable code and downloadable workbook, on doing this in Excel/VBA on my blog:

Here’s the code:

```
'Arguments
'List: The range to be normalized.
'RepeatingColsCount: The number of columns, starting with the leftmost,
' whose headings remain the same.
'NormalizedColHeader: The column header for the rolled-up category.
'DataColHeader: The column header for the normalized data.
'NewWorkbook: Put the sheet with the data in a new workbook?
'
'NOTE: The data must be in a contiguous range and the
'rows that will be repeated must be to the left,
'with the rows to be normalized to the right.
Sub NormalizeList(List As Excel.Range, RepeatingColsCount As Long, _
NormalizedColHeader As String, DataColHeader As String, _
Optional NewWorkbook As Boolean = False)
Dim FirstNormalizingCol As Long, NormalizingColsCount As Long
Dim ColsToRepeat As Excel.Range, ColsToNormalize As Excel.Range
Dim NormalizedRowsCount As Long
Dim RepeatingList() As String
Dim NormalizedList() As Variant
Dim ListIndex As Long, i As Long, j As Long
Dim wbSource As Excel.Workbook, wbTarget As Excel.Workbook
Dim wsTarget As Excel.Worksheet
With List
'If the normalized list won't fit, you must quit.
If .Rows.Count * (.Columns.Count - RepeatingColsCount) > .Parent.Rows.Count Then
MsgBox "The normalized list will be too many rows.", _
vbExclamation + vbOKOnly, "Sorry"
Exit Sub
End If
'You have the range to be normalized and the count of leftmost rows to be repeated.
'This section uses those arguments to set the two ranges to parse
'and the two corresponding arrays to fill
FirstNormalizingCol = RepeatingColsCount + 1
NormalizingColsCount = .Columns.Count - RepeatingColsCount
Set ColsToRepeat = .Cells(1).Resize(.Rows.Count, RepeatingColsCount)
Set ColsToNormalize = .Cells(1, FirstNormalizingCol).Resize(.Rows.Count, NormalizingColsCount)
NormalizedRowsCount = ColsToNormalize.Columns.Count * .Rows.Count
ReDim RepeatingList(1 To NormalizedRowsCount, 1 To RepeatingColsCount)
ReDim NormalizedList(1 To NormalizedRowsCount, 1 To 2)
End With
'Fill in every i elements of the repeating array with the repeating row labels.
For i = 1 To NormalizedRowsCount Step NormalizingColsCount
ListIndex = ListIndex + 1
For j = 1 To RepeatingColsCount
RepeatingList(i, j) = List.Cells(ListIndex, j).Value2
Next j
Next i
'We stepped over most rows above, so fill in other repeating array elements.
For i = 1 To NormalizedRowsCount
For j = 1 To RepeatingColsCount
If RepeatingList(i, j) = "" Then
RepeatingList(i, j) = RepeatingList(i - 1, j)
End If
Next j
Next i
'Fill in each element of the first dimension of the normalizing array
'with the former column header (which is now another row label) and the data.
With ColsToNormalize
For i = 1 To .Rows.Count
For j = 1 To .Columns.Count
NormalizedList(((i - 1) * NormalizingColsCount) + j, 1) = .Cells(1, j)
NormalizedList(((i - 1) * NormalizingColsCount) + j, 2) = .Cells(i, j)
Next j
Next i
End With
'Put the normal data in the same workbook, or a new one.
If NewWorkbook Then
Set wbTarget = Workbooks.Add
Set wsTarget = wbTarget.Worksheets(1)
Else
Set wbSource = List.Parent.Parent
With wbSource.Worksheets
Set wsTarget = .Add(after:=.Item(.Count))
End With
End If
With wsTarget
'Put the data from the two arrays in the new worksheet.
.Range("A1").Resize(NormalizedRowsCount, RepeatingColsCount) = RepeatingList
.Cells(1, FirstNormalizingCol).Resize(NormalizedRowsCount, 2) = NormalizedList
'At this point there will be repeated header rows, so delete all but one.
.Range("1:" & NormalizingColsCount - 1).EntireRow.Delete
'Add the headers for the new label column and the data column.
.Cells(1, FirstNormalizingCol).Value = NormalizedColHeader
.Cells(1, FirstNormalizingCol + 1).Value = DataColHeader
End With
End Sub
```

You’d call it like this:

```
Sub TestIt()
NormalizeList ActiveSheet.UsedRange, 4, "Variable", "Value", False
End Sub
```

### Answer：

You’ll need to change the names of wsSource and wsTarget to their actual sheet names:

```
Sub tgr()
Dim wsSource As Worksheet
Dim wsTarget As Worksheet
Dim arrSource() As Variant
Dim arrData() As Variant
Dim rIndex As Long
Dim cIndex As Long
Dim DataIndex As Long
Dim lNumProjects As Long
Set wsSource = Sheets("Source")
Set wsTarget = Sheets("Target")
arrSource = wsSource.Range("A1").CurrentRegion.Value
lNumProjects = UBound(arrSource, 2) - 3
ReDim arrData(1 To lNumProjects * (UBound(arrSource, 1) - 1), 1 To 5)
For rIndex = 2 To UBound(arrSource, 1)
For cIndex = 1 To lNumProjects
DataIndex = DataIndex + 1
arrData(DataIndex, 1) = arrSource(rIndex, 1)
arrData(DataIndex, 2) = arrSource(rIndex, 2)
arrData(DataIndex, 3) = arrSource(rIndex, 3)
arrData(DataIndex, 4) = arrSource(1, cIndex + 3)
arrData(DataIndex, 5) = arrSource(rIndex, cIndex + 3)
Next cIndex
Next rIndex
If DataIndex > 0 Then
wsTarget.Range("A2:E" & Rows.Count).ClearContents
wsTarget.Range("A2:E2").Resize(DataIndex).Value = arrData
End If
Set wsSource = Nothing
Set wsTarget = Nothing
Erase arrSource
Erase arrData
End Sub
```
