vba remove duplicates and sum the value

I have table as below

date     -         value      -       units
-------------   ------------      ------------
02/02/2000     32.30            23
03/02/2000     22.30            20
03/02/2000     62.30            21

if there more than one occurance of same date, i need to retain just one occurance and sum the values on same date

hence above table will look as below

date     -         value      -       units
-------------   ------------      ------------
02/02/2000     32.30            23
03/02/2000     84.60            41

Assuming your dates are in A Column starting from row-1 and you want to sum column b and column c values then you can use the following code..

Sub moddata()
    Dim rng As Range, cell As Range, r As Range
    Dim lrow As Long, i As Long
    Dim rng1 As Range, rng2 As Range
    lrow = Cells(Cells.Rows.Count, "a").End(xlUp).Row

    Set rng = Range("A2:A" & lrow)
    Set rng1 = Range("b2:b" & lrow)
    Set rng2 = Range("c2:c" & lrow)
i = 2

Do Until i > Cells(Cells.Rows.Count, "a").End(xlUp).Row

        Set r = Range("A2:A" & i)

        If Application.WorksheetFunction.CountIf(r, Cells(i, "a")) > 1 Then
            Cells(i, "b").Value = Application.WorksheetFunction.SumIf(rng, DateValue(Cells(i, "A").Value), rng1)
            Cells(i, "c").Value = Application.WorksheetFunction.SumIf(rng, DateValue(Cells(i, "A").Value), rng2)

i = i + 1

        End If

End Sub

Hello cynx,

this looks like the perfect scenario for a pivot table.

Get started here: http://peltiertech.com/Excel/Pivots/pivotstart.htm

or post a workbook, so we can help you out in your own file.

Post only dummy data, no confidential data, please.

cheers, teylyn

thanks guys, yes i am familiar with pivot tables, but i require this to be done thru vba since i am working on a macro and i am required to convert the files first in above format.

I will try saurabh's code and get back !

Why use VBA when native Excel can provide the same functionality much more efficiently?

Isn't that counter-productive and against good practice and spreadsheet design?

Many askers want a VBA solution (apparently), but it seems they don't know about the functionality Excel offers without macros. Just because it can be done with VBA does not mean it's the best way to do it.

I'd go for the pivot table over a VBA solution any time. It's definitely faster and more flexible.

I thought about pivot table as well but when i re-read and tag zones he head visual basic programming and which gave me a feeler that he is looking for code solution which is just coming by my experience and that;s the reason a code..

Thanks !

@teylyn: i preferred VBA solution, since i need to use these sheets as input to my macro. if there are 100s of such sheets, a click of button and let the code behind do the job is more productive rather user creating pivot for each !

@saurabh: the code works perfect as i require !
