Here’s a generic “unpivot” approach (all “fixed” columns must appear on the left of the columns to be unpivoted)
Test sub:
Sub Tester()
Dim p
'get the unpivoted data as a 2-D array
p = UnPivotData(Sheets("Sheet1").Range("A1").CurrentRegion, _
3, False, False)
With Sheets("Sheet1").Range("H1")
.CurrentRegion.ClearContents
.Resize(UBound(p, 1), UBound(p, 2)).Value = p 'populate array to sheet
End With
'EDIT: alternative (slower) method to populate the sheet
' from the pivoted dataset. Might need to use this
' if you have a large amount of data
'Dim r As Long, c As Long
'For r = 1 To Ubound(p, 1)
'For c = 1 To Ubound(p, 2)
' Sheets("Sheet2").Cells(r, c).Value = p(r, c)
'Next c
'Next r
End Sub
UnPivot function – should not need any modifications:
Function UnPivotData(rngSrc As Range, fixedCols As Long, _
Optional AddCategoryColumn As Boolean = True, _
Optional IncludeBlanks As Boolean = True)
Dim nR As Long, nC As Long, data, dOut()
Dim r As Long, c As Long, rOut As Long, cOut As Long, cat As Long
Dim outRows As Long, outCols As Long
data = rngSrc.Value 'get the whole table as a 2-D array
nR = UBound(data, 1) 'how many rows
nC = UBound(data, 2) 'how many cols
'calculate the size of the final unpivoted table
outRows = nR * (nC - fixedCols)
outCols = fixedCols + IIf(AddCategoryColumn, 2, 1)
'resize the output array
ReDim dOut(1 To outRows, 1 To outCols)
'populate the header row
For c = 1 To fixedCols
dOut(1, c) = data(1, c)
Next c
If AddCategoryColumn Then
dOut(1, fixedCols + 1) = "Category"
dOut(1, fixedCols + 2) = "Value"
Else
dOut(1, fixedCols + 1) = "Value"
End If
'populate the data
rOut = 1
For r = 2 To nR
For cat = fixedCols + 1 To nC
If IncludeBlanks Or Len(data(r, cat)) > 0 Then
rOut = rOut + 1
'Fixed columns...
For c = 1 To fixedCols
dOut(rOut, c) = data(r, c)
Next c
'populate unpivoted values
If AddCategoryColumn Then
dOut(rOut, fixedCols + 1) = data(1, cat)
dOut(rOut, fixedCols + 2) = data(r, cat)
Else
dOut(rOut, fixedCols + 1) = data(r, cat)
End If
End If
Next cat
Next r
UnPivotData = dOut
End Function
