How to transpose cells in one column based on unique values in another column?
Supposing, you have a range of data which contains two columns, now, you want to transpose cells in one column to horizontal rows based on unique values in another column to get the following result. Do you have any good ideas to solve this problem in Excel?

Transpose cells in one column based on unique values with formulas
With the following array formulas, you can extract the unique values and transpose their corresponding data into horizontal rows, please do as follows:
1. Enter this array formula: =INDEX($A$2:$A$16, MATCH(0, COUNTIF($D$1:$D1, $A$2:$A$16), 0)) into a blank cell, D2, for example, and press Shift + Ctrl + Enter keys together to get the correct result, see screenshot:
Note: In the above formula, A2:A16 is the column that you want to list the unique values from, and D1 is the cell above this formula cell.
2. Then drag the fill handle down to the cells to extract all the unique values, see screenshot:
3. And then go on entering this formula into cell E2: =IFERROR(INDEX($B$2:$B$16, MATCH(0, COUNTIF($D2:D2,$B$2:$B$16)+IF($A$2:$A$16<>$D2, 1, 0), 0)), 0), and remember to press Shift + Ctrl + Enter keys to get the result, see screenshot:
Note: In above formula: B2:B16 is the column data that you want to transpose, A2:A16 is the column that you want to transpose the values based on, and D2 contains the unique value that you have extracted in Step 1.
4. Then drag the fill handle to right of the cells that you want to list the transposed data until displays 0, see screenshot:
5. And then continue dragging the fill handle down to the range of cells to get the transposed data as following screenshot shown:
Transpose cells in one column based on unique values with VBA code
May be the formulas are complex for you to understand, here, you can run the following VBA code to get the desired result you need.
1. Hold down the ALT + F11 keys to open the Microsoft Visual Basic for Applications window.
2. Click Insert > Module, and paste the following code in the Module Window.
VBA code: Transpose cells in one column based on unique values in another column:
Sub transposeunique()
'updateby Extendoffice 20151207
Dim xLRow As Long
Dim i As Long
Dim xCrit As String
Dim xCol As New Collection
Dim xRg As Range
Dim xOutRg As Range
Dim xTxt As String
Dim xCount As Long
Dim xVRg As Range
On Error Resume Next
xTxt = ActiveWindow.RangeSelection.Address
Set xRg = Application.InputBox("please select data range(only two columns):", "Kutools for Excel", xTxt, , , , , 8)
Set xRg = Application.Intersect(xRg, xRg.Worksheet.UsedRange)
If xRg Is Nothing Then Exit Sub
If (xRg.Columns.Count <> 2) Or _
(xRg.Areas.Count > 1) Then
MsgBox "the used range is only one area with two columns ", , "Kutools for Excel"
Exit Sub
End If
Set xOutRg = Application.InputBox("please select output range(specify one cell):", "Kutools for Excel", xTxt, , , , , 8)
If xOutRg Is Nothing Then Exit Sub
Set xOutRg = xOutRg.Range(1)
xLRow = xRg.Rows.Count
For i = 2 To xLRow
xCol.Add xRg.Cells(i, 1).Value, xRg.Cells(i, 1).Value
Next
Application.ScreenUpdating = False
For i = 1 To xCol.Count
xCrit = xCol.Item(i)
xOutRg.Offset(i, 0) = xCrit
xRg.AutoFilter Field:=1, Criteria1:=xCrit
Set xVRg = xRg.Range("B2:B" & xLRow).SpecialCells(xlCellTypeVisible)
If xVRg.Count > xCount Then xCount = xVRg.Count
xRg.Range("B2:B" & xLRow).SpecialCells(xlCellTypeVisible).Copy
xOutRg.Offset(i, 1).PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:=False, Transpose:=True
Application.CutCopyMode = False
Next
xOutRg = xRg.Cells(1, 1)
xOutRg.Offset(0, 1).Resize(1, xCount) = xRg.Cells(1, 2)
xRg.Rows(1).Copy
xOutRg.Resize(1, xCount + 1).PasteSpecial Paste:=xlPasteFormats
xRg.AutoFilter
Application.ScreenUpdating = True
End Sub
3. Then press F5 key to run this code, and a prompt box will pop out to remind you select the data range that you want to use, see screenshot:
4. And then click OK button, another prompt box will pop out to remind you to select a cell to put the result, see screenshot:
6. Click OK button, and the data in column B has been transposed based on unique values in column A, see screenshot:
