Remove Duplicates in a Column and enter Sum in another Column - excel

Question

I want to remove duplicates based on the text in Column I and sum the values in Column C, the data in the other columns doesn't matter.
I do not want a pivot table and I am aware they are the preferred option for this type of thing.
An example of what I'd like to achieve:
I found VBA code and tried to modify it. It doesn't delete all the lines.
Sub Sum_and_Dedupe()
With Worksheets("data")
'deal with the block of data radiating out from A1
With .Cells(1, 1).CurrentRegion
'step off the header and make one column wider
With .Resize(.Rows.Count - 1, .Columns.Count + 1).Offset(1, 0)
.Columns(.Columns.Count).Formula = "=sumifs(c:c, i:i, i2)"
.Columns(3) = .Columns(.Columns.Count).Value
.Columns(.Columns.Count).Delete
End With
'remove duplicates
.RemoveDuplicates Columns:=Array(9), Header:=xlYes
End With
.UsedRange
End With
End Sub

Answer 1

This should be an answer to your question.
However, code might require adaptation if the range in which you look becomes very long.
Option Explicit
Sub test()
Dim wb As Workbook
Dim ws As Worksheet
Dim LastRow As Long, LastCol As Long, a As Double, i As Long
Dim Rng As Range
Dim Cell As Variant, Estimate As Variant
Set wb = ThisWorkbook
Set ws = wb.Sheets(1)
LastRow = ws.Cells(ws.Rows.Count, "I").End(xlUp).Row
LastCol = ws.Cells(1, ws.Columns.Count).End(xlToLeft).Column
Set Rng = ws.Range(ws.Cells(2, 9), ws.Cells(LastRow, 9))
For Each Cell In Rng
i = 0
a = 0
For Each Estimate In Rng
If Estimate.Value = Cell.Value Then
i = i + 1 'Count nr of intances
a = a + ws.Cells(Estimate.Row, 3).Value 'sum booking value
If i > 1 Then
ws.Rows(Estimate.Row).Delete
i = 1
LastRow = LastRow - 1
End If
End If
Next Estimate
ws.Cells(Cell.Row, 3).Value = a 'Enter sum in booked this week
Next Cell
End Sub

Answer 2

You'll either need to change your current sheet name to data, or change the first two lines of this code to fit your needs. sh = the data sheet that you showed us. osh = an output sheet that this code will generate. Note also if column C or I move you can update the positions easily by changing colBooked and colEstimate. If you have more than a thousand unique estimate entries then make the array number larger than 999.
Sub summariseEstimates()
Dim sh As String: sh = "data"
Dim osh As String: osh = "summary"
Dim colBooked As Integer: colBooked = 3
Dim colEstimate As Integer: colEstimate = 9
Dim myArray(999) As String
Dim shCheck As Worksheet
Dim output As Worksheet
Dim lastRow As Long
Dim a As Integer: a = 0
Dim b As Integer
Dim r As Long 'row anchor
Dim i As Integer 'sheets
'Build summary array:
With Worksheets(sh)
lastRow = .Cells.Find("*", searchorder:=xlByRows, searchdirection:=xlPrevious).Row
For r = 2 To lastRow
If r = 2 Then 'first entry
myArray(a) = .Cells(r, colEstimate) & "," & .Cells(r, colBooked)
Else
For b = 0 To a
If VBA.LCase(VBA.Replace(.Cells(r, colEstimate), " ", "")) = VBA.LCase(VBA.Replace(VBA.Split(myArray(b), ",")(0), " ", "")) Then 'match
myArray(b) = VBA.Split(myArray(b), ",")(0) & "," & VBA.Split(myArray(b), ",")(1) + .Cells(r, colBooked)
Exit For
End If
Next b
If b = a + 1 Then 'completed loop = no match, create new array item:
a = a + 1
myArray(a) = .Cells(r, colEstimate) & "," & .Cells(r, colBooked)
End If
End If
Next r
End With
'Create summary sheet:
On Error Resume Next
Set shCheck = Worksheets(osh)
If Err.Number <> 0 Then
On Error GoTo 0
Set output = Worksheets.Add(After:=Worksheets(sh))
output.Name = osh
Err.Clear
Else
On Error GoTo 0
If MsgBox("*" & osh & "* sheet already exists. Proceed to delete and recreate?", vbOKCancel, "Summary") = vbCancel Then
Exit Sub
Else
Application.DisplayAlerts = False
Worksheets(osh).Delete
Set output = Worksheets.Add(After:=Worksheets(sh))
output.Name = osh
End If
End If
'Output to summary sheet:
With Worksheets(osh)
.Cells(1, 1).Value = "ESTIMATE"
.Cells(1, 2).Value = "BOOKED THIS WEEK"
For b = 0 To a
.Cells(b + 2, 1).Value = VBA.Split(myArray(b), ",")(0)
.Cells(b + 2, 2).Value = VBA.Split(myArray(b), ",")(1)
Next b
.Columns("A:B").AutoFit
End With
End Sub
