Transpose multiple columns to multiple rows with VBA - excel

Question

This is the kind of transformation is what I am trying to perform.
For illustration I made this as table. Basically the first three columns should repeat for however many colors are available.
I searched for similar questions but could not find when I want multiple columns to repeat.
I found this code online
Sub createData()
Dim dSht As Worksheet
Dim sSht As Worksheet
Dim colCount As Long
Dim endRow As Long
Dim endRow2 As Long
Set dSht = Sheets("Sheet1") 'Where the data sits
Set sSht = Sheets("Sheet2") 'Where the transposed data goes
sSht.Range("A2:C60000").ClearContents
colCount = dSht.Range("A1").End(xlToRight).Column
'// loops through all the columns extracting data where "Thank" isn't blank
For i = 2 To colCount Step 2
endRow = dSht.Cells(1, i).End(xlDown).Row
For j = 2 To endRow
If dSht.Cells(j, i) <> "" Then
endRow2 = sSht.Range("A50000").End(xlUp).Row + 1
sSht.Range("A" & endRow2) = dSht.Range("A" & j)
sSht.Range("B" & endRow2) = dSht.Cells(j, i)
sSht.Range("C" & endRow2) = dSht.Cells(j, i).Offset(0, 1)
End If
Next j
Next i
End Sub
I tried changing step 2 to 1 and j to start from 4.

Answer 1

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

Answer 2

Here is one way (fastest?) using arrays. This approach is better that the linked question as it doesn't read and write to/from range objects in a loop. I have commented the code so you shouldn't have a problem understanding it.
Option Explicit
Sub Sample()
Dim wsThis As Worksheet, wsThat As Worksheet
Dim ThisAr As Variant, ThatAr As Variant
Dim Lrow As Long, Col As Long
Dim i As Long, k As Long
Set wsThis = Sheet1: Set wsThat = Sheet2
With wsThis
'~~> Find Last Row in Col A
Lrow = .Range("A" & .Rows.Count).End(xlUp).Row
'~~> Find total value in D,E,F so that we can define output array
Col = Application.WorksheetFunction.CountA(.Range("D2:F" & Lrow))
'~~> Store the values from the range in an array
ThisAr = .Range("A2:F" & Lrow).Value
'~~> Define your new array
ReDim ThatAr(1 To Col, 1 To 4)
'~~> Loop through the array and store values in new array
For i = LBound(ThisAr) To UBound(ThisAr)
k = k + 1
ThatAr(k, 1) = ThisAr(i, 1)
ThatAr(k, 2) = ThisAr(i, 2)
ThatAr(k, 3) = ThisAr(i, 3)
'~~> Check for Color 1
If ThisAr(i, 4) <> "" Then ThatAr(k, 4) = ThisAr(i, 4)
'~~> Check for Color 2
If ThisAr(i, 5) <> "" Then
k = k + 1
ThatAr(k, 1) = ThisAr(i, 1)
ThatAr(k, 2) = ThisAr(i, 2)
ThatAr(k, 3) = ThisAr(i, 3)
ThatAr(k, 4) = ThisAr(i, 5)
End If
'~~> Check for Color 3
If ThisAr(i, 6) <> "" Then
k = k + 1
ThatAr(k, 1) = ThisAr(i, 1)
ThatAr(k, 2) = ThisAr(i, 2)
ThatAr(k, 3) = ThisAr(i, 3)
ThatAr(k, 4) = ThisAr(i, 6)
End If
Next i
End With
'~~> Create headers in Sheet2
Sheet2.Range("A1:D1").Value = Sheet1.Range("A1:D1").Value
'~~> Output the array
wsThat.Range("A2").Resize(Col, 4).Value = ThatAr
End Sub
SHEET1
SHEET2

Answer 3

The addition of the LET function allows for this non-VBA solution.
=LET(data,B3:F6,
dataRows,ROWS(data),
dataCols,COLUMNS(data),
rowHeaders,OFFSET(data,0,-1,dataRows,1),
colHeaders,OFFSET(data,-1,0,1,dataCols),
dataIndex,SEQUENCE(dataRows*dataCols),
rowIndex,MOD(dataIndex-1,dataRows)+1,
colIndex,INT((dataIndex-1)/dataRows)+1,
FILTER(CHOOSE({1,2,3}, INDEX(rowHeaders,rowIndex), INDEX(colHeaders,colIndex), INDEX(data,rowIndex,colIndex)), index(data,rowIndex,colIndex)<>""))

Answer 4

Below is a custom function I wrote for such things (demo video I posted on YouTube). A few differences from other answers:
The custom function allows for more than one axis in columns. As shown below, the column axis has Currency and Time.
Row axis does not need to be directly next to the data range.
One can specify the entire row as the column axis or the entire column to specify the row axis. See formula used as example below.
So with this data set:
And entering this as the formula:
=unPivotData(D4:G7,2:3,B:C)
an output of this:
Function unPivotData(theDataRange As Range, theColumnRange As Range, theRowRange As Range, _
Optional skipZerosAsTrue As Boolean, Optional includeBlanksAsTrue As Boolean)
'Set effecient range
Dim cleanedDataRange As Range
Set cleanedDataRange = Intersect(theDataRange, theDataRange.Worksheet.UsedRange)
'tests Data ranges
With cleanedDataRange
'Use intersect address to account for users selecting full row or column
If .EntireColumn.Address <> Intersect(.EntireColumn, theColumnRange).EntireColumn.Address Then
unPivotData = "datarange missing Column Ranges"
ElseIf .EntireRow.Address <> Intersect(.EntireRow, theRowRange).EntireRow.Address Then
unPivotData = "datarange missing row Ranges"
ElseIf Not Intersect(cleanedDataRange, theColumnRange) Is Nothing Then
unPivotData = "datarange may not intersect column range. " & Intersect(cleanedDataRange, theColumnRange).Address
ElseIf Not Intersect(cleanedDataRange, theRowRange) Is Nothing Then
unPivotData = "datarange may not intersect row range. " & Intersect(cleanedDataRange, theRowRange).Address
End If
'exits if errors were found
If Len(unPivotData) > 0 Then Exit Function
Dim dimCount As Long
dimCount = theColumnRange.Rows.Count + theRowRange.Columns.Count
Dim aCell As Range, i As Long, g As Long
ReDim newdata(dimCount, i)
End With
'loops through data ranges
For Each aCell In cleanedDataRange.Cells
With aCell
If .Value2 = "" And Not (includeBlanksAsTrue) Then
'skip
ElseIf .Value2 = 0 And skipZerosAsTrue Then
'skip
Else
ReDim Preserve newdata(dimCount, i)
g = 0
'gets DimensionMembers members
For Each gcell In Union(Intersect(.EntireColumn, theColumnRange), _
Intersect(.EntireRow, theRowRange)).Cells
newdata(g, i) = IIf(gcell.Value2 = "", "", gcell.Value)
g = g + 1
Next gcell
newdata(g, i) = IIf(.Value2 = "", "", .Value)
i = i + 1
End If
End With
Next aCell
unPivotData = WorksheetFunction.Transpose(newdata)
End Function
