Counting Wins and Losses

Graham Davis has, in Excel, created a matrix of player names for his league. Cells B2:H2 contain the names of the players, as do cells A3:A9. At each intersection in the matrix, Graham places a "W" or "L" to indicate whether the match-up resulted in a win or loss for the player in each row. If a player plays another person more than once, then a cell contains a "W" or "L" for each game. Graham was wondering what formula could be used, starting in column I, to indicate the number or wins and losses for each player.

There are a number of ways you can get the desired information. One is to use this type of formula:

=LEN(SUBSTITUTE(B3&C3&D3&E3&F3&G3&H3,"L",""))

This formula calculates the number of non-L characters in row 3--in other words, the number of wins. It does this by concatenating the contents of B3:H3, and then using the SUBSTITUTE function to remove all the Ls. This leaves the Ws, which are counted by the LEN function. You could also use the CONCATENATE function, in the following manner, for the same result:

=LEN(SUBSTITUTE(CONCATENATE(B3,C3,D3,E3,F3,G3,H3),"L",""))

To calculate the number of losses, simply replace "L" in each formula with "W".

You can also use an array formula, which allows you to specify a range of cells to examine, rather than needing to specify every single cell:

=SUM(LEN(SUBSTITUTE(B3:H3, "L","")))

This array formula, entered by pressing Shift+Ctrl+Enter, returns the number of wins (W characters) in the range B3:H3.

Finally, you can use a user-defined function to return the occurrences of a specific character within a given range. The following macro will do the trick:

Function CharNums(r, chr) As Integer
    Dim c As Range
    Dim strX As String
    Dim J As Integer

    Application.Volatile
    CharNums = 0
    For Each c In r.Cells
        strX = c.Value
        For J = 1 To Len(strX)
            If Mid(strX, J, 1) = chr Then CharNums = CharNums + 1
        Next J
    Next c
End Function

To use the function, you would us a formula like this in your worksheet:

=CharNums(B3:H3;"W")

The function returns the number of uppercase W characters in the range. All other characters (including lowercase w characters) are ignored. To count losses, simply substitute L for W in the formula.
