Combine Rows & Sum Values in a Worksheet - excel

Question

I have an excel sheet with the below (pipe "|" to delimit columns) data.
A|B|C|X|50|60
D|E|F|X|40|30
A|B|C|X|10|20
A|B|C|Y|20|20
A|B|C|X|20|70
D|E|F|X|10|50
A|B|C|Y|10|10
The result I am trying to get is:
A|B|C|X|80|150
A|B|C|Y|30|30
D|E|F|X|50|80
Values A, B, C and D, E, F are like unique identifiers. Actually only A or D can be considered. Values X and Y are like "types", and the integers are the values to sum. This sample was simplified, there are thousands of unique identifiers, dozen of types and dozens of values to sum. The rows are not sorted, the types can be located in higher or lower rows. I am trying to avoid the use of a pivot table.
Dim LastRow As Integer
Dim LastCol As Integer
Dim i As Integer
LastCol = Sheets(1).Cells(1, Columns.Count).End(xlToLeft).Column
LastRow = Sheets(1).Cells(Rows.Count, 1).End(xlUp).Row
For i = 1 To LastRow
????
Next i
The code above gets to the point of looping through the rows but I am unclear on what to after that point.

Answer 1

Sort them on all alphabetic columns you deem important.
In an unused column to the right use a formula like the following in the second row,
=IF($A2&$B2&$C2&$D2=$A3&$B3&$C3&$D3, "", SUMIFS(E:E,$A:$A, $A2,$B:$B, $B2,$C:$C, $C2,$D:$D, $D2))
Copy that formula right one column then fill both columns down as far as your data goes
Filter on the two columns, removing blanks.
        
Optionally copy the data to a new report worksheet and remove columns E & F.
Addendum:
A more automated approach could be achieved with some form of array and some simple mathematical operations. I've chosen a dictionary object in order to take use of its indexed Key to recognize patterns in the first four alphabetic identifiers.
To use a scripting dictionary, you need to go into the VBE's Tools ► References and add Microsoft Scripting Runtime. The following code will not compile without it.
The following has been adjusted for dynamic columns of keys and integers.
Sub rad_collection()
Dim rw As Long, nc As Long, sTMP As String, v As Long, vTMP As Variant
Dim i As Long, iNumKeys As Long, iNumInts As Long
Dim dRADs As New Scripting.Dictionary
dRADs.CompareMode = vbTextCompare
iNumKeys = 5 'possibly calculated by num text (see below)
iNumInts = 2 'possibly calculated by num ints (see below)
With ThisWorkbook.Sheets("Sheet4").Cells(1, 1).CurrentRegion
'iNumKeys = Application.CountA(.Rows(2)) - Application.Count(.Rows(2)) 'alternate count of txts
'iNumInts = Application.Count(.Rows(2)) 'alternate count of ints
For rw = 2 To .Cells(Rows.Count, 1).End(xlUp).row
vTMP = .Cells(rw, 1).Resize(1, iNumKeys).Value2
sTMP = Join(Application.Index(vTMP, 1, 0), Chr(183))
If Not dRADs.Exists(sTMP) Then
dRADs.Add Key:=sTMP, Item:=Join(Application.Index(.Cells(rw, iNumKeys + 1).Resize(1, iNumInts).Value2, 1, 0), Chr(183))
Else
vTMP = Split(dRADs.Item(sTMP), Chr(183))
For v = LBound(vTMP) To UBound(vTMP)
vTMP(v) = vTMP(v) + .Cells(rw, iNumKeys + 1 + v).Value2
Next v
dRADs.Item(sTMP) = Join(vTMP, Chr(183))
End If
Next rw
rw = 1
nc = iNumKeys + iNumInts + 1
.Cells(rw, nc + 1).CurrentRegion.ClearContents 'clear previous
.Cells(rw, nc + 1).Resize(1, nc - 1) = .Cells(rw, 1).Resize(1, nc - 1).Value2
For Each vTMP In dRADs.Keys
'Debug.Print vTMP & "|" & dRADs.Item(vTMP)
rw = rw + 1
.Cells(rw, nc + 1).Resize(1, iNumKeys) = Split(vTMP, Chr(183))
.Cells(rw, nc + iNumKeys + 1).Resize(1, iNumInts) = Split(dRADs.Item(vTMP), Chr(183))
.Cells(rw, nc + iNumKeys + 1).Resize(1, iNumInts) = _
.Cells(rw, nc + iNumKeys + 1).Resize(1, iNumInts).Value2
Next vTMP
End With
dRADs.RemoveAll: Set dRADs = Nothing
End Sub
Just run the macro against the numbers you have provided as samples. I've assumed some form of column header labels in the first row. The dictionary object is populated and duplicates in the combined identifiers have their numbers summed. All that is left is to split them back up and return them to the worksheet in an unused area.
    
Location of Microsoft Scripting Runtime - In the Visual Basic Editor (aka VBE) choose Tools ► References (Alt+T,R) and scroll down a little more than halfway to find it.
