如何从逗号分隔的单元格中查找多个值并在excel中平均结果？

Question

I'm trying to build a formula that can lookup multiple ISO country codes separated by comma contained in one cell (Cell A2, Image 1) with a reference to a list of country codes and education scoring (Columns F and G, Image 1). Then return the average of the scores of all countries on cell B2. does anyone know if I can build a formula to handle that?

Answer 1

I didn't think you could do this with cell formula, but then I saw this post and came up with this:

=AVERAGE(IF(ISNA(MATCH($F$2:$F$99, TRIM(MID(SUBSTITUTE(A2,",",REPT(" ",99)),(ROW(OFFSET($A$1,,,LEN(A2)-LEN(SUBSTITUTE(A2,",",""))+1))-1)*99+((ROW(OFFSET($A$1,,,LEN(A2)-LEN(SUBSTITUTE(A2,",",""))+1)))=1),99)), 0)), "",  $G$2:$G$99 ))

Try pasting into cell B2 as an array formula (Ctrl + Shift + Enter) and fill-down... And don't ask me how it works.

You could try VBA:

Option Explicit

Sub test()

    Dim i As Long
    Dim strCode As String, strScore As String
    Dim rngVlookup As Range
    Dim Code As Variant

    With ThisWorkbook.Worksheets("Sheet1")

        Set rngVlookup = .Range("F2:G34")

        For i = 2 To 3

        strCode = ""
        strScore = ""

            strCode = .Range("A" & i).Value

            For Each Code In Split(strCode, ",")
                If strScore = "" Then
                    On Error Resume Next
                    strScore = Application.WorksheetFunction.VLookup(Trim(Code), rngVlookup, 2, False)
                Else
                    On Error Resume Next
                    strScore = strScore & ", " & Application.WorksheetFunction.VLookup(Trim(Code), rngVlookup, 2, False)
                End If

            Next Code

            With .Range("B" & i)
                .Value = strScore
                .NumberFormat = "0.000000"
            End With

        Next i

    End With

End Sub
