ravia2buri,
Welcome to the MrExcel forum.
Here is a macro solution for you to consider, that is based on your flat text display.
Please TEST this FIRST in a COPY of your workbook (always make a backup copy before trying new code, you never know what you might lose).
1. Copy the below code
2. Open your NEW workbook
3. Press the keys
ALT +
F11 to open the Visual Basic Editor
4. Press the keys
ALT +
I to activate the Insert menu
5. Press
M to insert a Standard Module
6. Where the cursor is flashing, paste the code
7. Press the keys
ALT +
Q to exit the Editor, and return to Excel
8. To run the macro from Excel press
ALT +
F8 to display the Run Macro Dialog. Double Click the macro's name to Run it.
Code:
Sub SumUniques()
' hiker95, 12/12/2017, ME1034963
Application.ScreenUpdating = False
Dim r As Long, lr As Long, n As Long, i As Long, tot As Long
With ActiveSheet
lr = .Cells(Rows.Count, 2).End(xlUp).Row
For r = 2 To lr
n = Application.CountIf(.Columns(2), .Cells(r, 2).Value)
If n = 1 Then
.Range("C" & r).Value = .Range("A" & r).Value
ElseIf n > 1 Then
tot = 0
For i = r To r + n - 1
tot = tot + .Range("A" & i).Value
Next i
With .Range("C" & r + n - 1)
.Value = tot
.NumberFormat = "#,##0"
End With
End If
r = r + n - 1
Next r
End With
Application.ScreenUpdating = True
End Sub
Before you use the macro with
Excel 2007 or newer, save your workbook, Save As, a macro enabled workbook with the file extension
.xlsm, and, answer the "do you want to enable macros" question as "yes" or "OK" (depending on the button label for your version of Excel) the next time you open your workbook.
Then run the
SumUniques macro.
