In Excel, it's a common scenario to encounter a dataset with duplicate entries. Often, you might find yourself with a range of data where the key challenge is to efficiently combine these duplicate rows while simultaneously summing up the values in a corresponding column as following screenshot shown. In this context, we'll delve into several practical methods that can help you consolidate duplicate data and aggregate their associated values, enhancing both the clarity and utility of your Excel workbooks.

Combine duplicate rows and sum the values with the Consolidate function

The Consolidate is a useful tool for us to consolidate multiple worksheets or rows in Excel, with this feature, we can combine duplicate rows and sum up their corresponding values quickly and easily. Please do with the following steps:

Step 1: Select a Destination Cell

Choose where you want the consolidated data to appear.

Step 2: Access the Consolidate Function and set up the consolidation

  1. Click Data > Consolidate, see screenshot:
  2. In the Consolidate dialog box:
    • (1.) Select Sum from Function drop down list;
    • (2.) Click to select the range that you want to consolidate in the Reference box;
    • (3.) Check Top row and Left column from Use labels in option;
    • (4.) Finally, click OK button.


Excel will combine any duplicates found in the first column and sum their corresponding values in the adjacent columns as following screenshot shown:

  • If the range doesn't include a header row, ensure to uncheck Top row from the Use labels in option.
  • With this feature, calculations can only be consolidated based on the first column (the leftmost one) of the data.

Combine duplicate rows and sum the values with a powerful feature – Kutools

If you have installed Kutools for Excel, its Advanced Combine Rows feature allows you to easily combine duplicate rows, providing options to sum, count, average, or execute other calculations on your data. Moreover, this feature isn't limited to just one key column, it can handle multiple key columns, making complex data consolidation tasks much easier.

Note: If you want to use this Advanced Combine Rows feature, please download and install Kutools for Excel first.

After installing Kutools for Excel, select the data range, and then click Kutools > Merge & Split > Advanced Combine Rows.

In the Advanced Combine Rows dialog box, please set the following operations:

  1. Click the column name that you want to combine duplicates based on, here, I will click Product, and then select Primary Key from the drop-down list in the Operation column;
  2. Then, select the column name you want to sum the values, and then select Sum from the drop-down list in the Operation column;
  3. As for the other columns, you can choose the operation you need, such as combining the values with a specific separator or performing a certain calculation; (this step can be ignored if you have only two columns)
  4. At last, you can preview the combined result then click OK button.


Now, the duplicate values in the key column are combined, and other corresponding values are summed up as following screenshot shown:

  • With this useful feature, you can also combine rows based on duplicate cell value as following demo shown:
  • This feature supports Undo, if you want to recover your original data, just press Ctrl + Z.
  • To apply this feature, please download and install Kutools for Excel first.

Combine duplicate rows and sum the values with the Pivot Table

Pivot Table in Excel provide a dynamic way to rearrange, group, and summarize data. This functionality becomes incredibly useful when you are faced with a dataset filled with duplicate entries and need to sum corresponding values.

Step 1: Creating a Pivot Table

  1. Select the data range. And then, go to the Insert tab, and click Pivot Table, see screenshot:
  2. In the popped-out dialog box, choose where you want the Pivot Table report to be placed, you can put it to a new sheet or existing sheet as you need. Then, click OK. See screenshot:
  3. Now, a Pivot Table is inserted in the selected destination cell. See screenshot:

Step 2: Configuring the Pivot Table:

  1. In the PivotTable Fields pane, drag the field containing duplicates to the Row area. This will group your duplicates.
  2. Next, drag the fields with the values you want to sum to the Values area. By default, Excel sums the values. See the demo below:


The Pivot Table now displays your data with duplicates combined and their values summed up, offering a clear and concise view for analysis. See screenshot:

Combine duplicate rows and sum the values with VBA code

If you are interested in VBA code, in this section, we will give a VBA code to consolidate duplicate rows and sum the corresponding values in other columns. Please do with the following steps:

Step 1: Open the VBA sheet module editor and copy the code

  1. Hold down the ALT + F11 keys in Excel to open the Microsoft Visual Basic for Applications window.
  2. Click Insert > Module, and paste the following code in the Module Window.
    VBA code: Combine duplicate rows and sum the values
    Sub CombineDuplicateRowsAndSumForMultipleColumns()
    'Update by Extendoffice
        Dim SourceRange As Range, OutputRange As Range
        Dim Dict As Object
        Dim DataArray As Variant
        Dim i As Long, j As Long
        Dim Key As Variant
        Dim ColCount As Long
        Dim SumArray() As Variant
        Dim xArr As Variant
        Set SourceRange = Application.InputBox("Select the original range:", "Kutools for Excel", Type:=8)
        If SourceRange Is Nothing Then Exit Sub
        ColCount = SourceRange.Columns.Count
        Set OutputRange = Application.InputBox("Select a cell for output:", "Kutools for Excel", Type:=8)
        If OutputRange Is Nothing Then Exit Sub
        Set Dict = CreateObject("Scripting.Dictionary")
        DataArray = SourceRange.Value
        For i = 1 To UBound(DataArray, 1)
            Key = DataArray(i, 1)
            If Not Dict.Exists(Key) Then
                ReDim SumArray(1 To ColCount - 1)
                For j = 2 To ColCount
                    SumArray(j - 1) = DataArray(i, j)
                Next j
                Dict.Add Key, SumArray
                xArr = Dict(Key)
                For j = 2 To ColCount
                    xArr(j - 1) = xArr(j - 1) + DataArray(i, j)
                Next j
                Dict(Key) = xArr
            End If
        Next i
        OutputRange.Resize(Dict.Count, ColCount).ClearContents
        i = 1
        For Each Key In Dict.Keys
            OutputRange.Cells(i, 1).Value = Key
            For j = 1 To ColCount - 1
                OutputRange.Cells(i, j + 1).Value = Dict(Key)(j)
            Next j
            i = i + 1
        Next Key
        Set Dict = Nothing
        Set SourceRange = Nothing
        Set OutputRange = Nothing
    End Sub

Step 2: Execute the code

  1. After pasting this code, please press F5 key to run this code. In the prompt box, select the data range that you want to combine and sum. And then, click OK.
  2. And in the next prompt box, select a cell where you will output the result, and click OK.


Now, the duplicate rows are merged, and their corresponding values have been summed up. See screenshot:

Combining and summing duplicate rows in Excel can be simple and efficient.
