Written by Allen Wyatt (last updated June 10, 2023)**This tip applies to** Excel 2007, 2010, 2013, 2016, 2019, Excel in Microsoft 365, and 2021

Srinivas has data in both columns A and B. He needs to sum the values in column B for which the cell format of the corresponding cells in column A are yellow. For instance, if the format in cell A17 is yellow, then the value in cell B17 should be included in the sum.

There are numerous macros available on the Internet (including at *ExcelTips*) that allow you to do conditional summing based on the color or other format of a cell. This need is different, however, in that it is not the color of the cell at issue, but the color of the cell one column to the left. This can still be done using a macro, as shown here:

Function SumNextYellow(ByVal r As Range) Dim c As Range Dim a As Double For Each c In r If c.Offset(0, -1).Interior.ColorIndex = 6 Then 'Yellow a = a + c.Value End If Next c SumNextYellow = a End Function

The function can be used in a worksheet formula, and accepts a range reference as an argument. It then steps through each cell in the range, and if the cell just to the left is yellow, then the value is included in the sum. (You should note that the ColorIndex used in the macro should be tested with your version of Excel to make sure that it is applicable; it may be different in different versions.)

A much more robust example is shown in the following listing. This function accepts one or more ranges of cells, along with an argument that represents a sample of the formatting you want to use.

Function ColorConditionSum(cSample As Excel.Range, rng As Excel.Range) ' This Function returns sum of values in rng.Columns(2) if ' corresponding cell in rng.Columns(1) is colored with sample ' color (cSample cell) ' Arguments: cSample = cell colored by sample color ' rng = cell range to be processed (2 columns) Dim rngCol2 As Excel.Range Dim rngConstants As Excel.Range Dim rngFormulas As Excel.Range Dim lColorIndex As Long Dim MySum As Double Dim area As Excel.Range Dim c As Excel.Range ColorConditionSum = False If Not TypeOf cSample Is Excel.Range Then Exit Function '>>> lColorIndex = cSample.Interior.ColorIndex MySum = 0 Set rngCol2 = Nothing If TypeOf rng Is Excel.Range Then If rng.Columns.Count < 2 Then Exit Function '>>> On Error Resume Next For Each area In rng.Areas If rngCol2 Is Nothing Then Set rngCol2 = area.Columns(2).SpecialCells(xlCellTypeConstants, 1) If rngCol2 Is Nothing Then Set rngCol2 = area.Columns(2).SpecialCells(xlCellTypeFormulas, 1) Else Set rngCol2 = Application.Union( _ rngCol2, area.Columns(2).SpecialCells(xlCellTypeFormulas, 1)) End If Else Set rngCol2 = Application.Union( _ rngCol2, area.Columns(2).SpecialCells(xlCellTypeConstants, 1)) Set rngCol2 = Application.Union( _ rngCol2, area.Columns(2).SpecialCells(xlCellTypeFormulas, 1)) End If Next area For Each area In rngCol2.Areas For Each c In area.Cells With c.Offset(0, -1) If .Interior.ColorIndex = lColorIndex Then MySum = MySum + c.Value End If End With Next c Next area End If ColorConditionSum = MySum End Function

You use this function in the following manner in a worksheet:

=ColorConditionSum(A10, A12:B22)

In this case, A10 is a cell that has the interior color you want to match, and A12:B22 is the range of cells to be evaluated. The values are pulled from the second column in the range and the formatting is checked on the cells in the first column.

1. Both versions of the function use the ColorIndex property to identify a cell's interior color. This represents an approximation of a limited number of colors (56) in the current color palette. A more specific representation is provided by the Color property. To implement this improvement, use Ctrl+H in the VB Editor to remove Index from each instance of ColorIndex; there are 5 instances (including variable lColorIndex).

2. In the simplified version of the function, if its first argument is a range like A10:B22, its first cell (A10) determines the target color. The original version improperly ignores this issue.

3. The function's second argument can be a parenthesized non-contiguous range like (A12:B15,A17:B22,D12:F20). In this case each subrange (area) must have at least two columns; if there are more than two, only the first two apply. Each cell in the second column of each area is summed if its adjacent cell in the first column matches the target color.

4. The original version of the function used the Range.SpecialCells method to identify cells with numeric values, but that method is unreliable in a user-defined function (UDF) that is referenced in a cell formula. It is not used in the simplified version.

Function ColorConditionSum(cSample As Range, rng As Range)

'Return the sum of each cell in rng.Columns(2) if the corresponding

'cell in rng.Columns(1) has the same color as the first cell in cSample

Dim lColorIndex As Long, MySum As Double, area As Range, c As Range

Const sTypes As String = "Double/Date/Currency" 'types to sum

ColorConditionSum = CVErr(xlErrValue)

lColorIndex = cSample.Cells(1).Interior.ColorIndex

For Each area In rng.Areas

If area.Columns.Count < 2 Then Exit Function '>>>

For Each c In area.Columns(2).Cells

If c.Offset(0, -1).Interior.ColorIndex = lColorIndex _

And InStr(sTypes, TypeName(c.Value)) > 0 _

Then MySum = MySum + c.Value

Next c

Next area

ColorConditionSum = MySum

End Function

Notice cells with numeric values (not text, logical, or empty) generally have VBA type Double. However, numeric cells with Number format Date, Currency, or Accounting (equivalent to Currency) are exceptions. These are included in Excel's SUM function and in both versions of the ColorConditionSum function.
