Counting Commas in a Selection

by Allen Wyatt
(last updated July 12, 2014)

At work, Mark regularly needs to count the number of commas in a range of selected cells. He can't find an Excel function to do this type of task, and is wondering if a macro might be able to do the trick.

While there is no worksheet function that will produce the desired count, there is a formula or two you can use. If you just want to know the number of cells that have at least one comma in them, the following formula will work just fine:

=COUNTIF(A1:A10,"*,*")

If you, instead, need to figure out the number of commas in the range when there could be multiple commas per cell, then you need to use a different formula:

=SUM(LEN(A1:A10))-SUM(LEN(SUBSTITUTE(A1:A10,",","")))

This formula should be entered as an array formula, which means that you should use Ctrl+Shift+Enter to enter the formula. If you need to derive the count for a different range, just change the range in two places in the formula.

If you prefer, you could also create a user-defined function to count the number of commas. There are multiple ways to approach such a task; the following is just one example.

Function CountComma(rng As Range)
    Dim iCount As Integer
    Dim rCell As Range
    Dim sTemp As String

    Application.Volatile
    iCount = 0
    For Each rCell In rng
        sTemp = Application.WorksheetFunction. _
          Substitute(rCell.Value, ",", "")
        iCount = iCount + _
          (Len(rCell.Value) - Len(sTemp))
    Next
    CountComma = iCount
    Set rCell = Nothing
    Set rng = Nothing
End Function

In order to use the function in the worksheet, enter the following into a cell:

=CountComma(A1:A10)

All of these methods described so far will count commas that are actually in the cell. They will not count commas that appear to be in the cell because of formatting. For instance, if a number appears as "1,234" in a cell, chances are good that the comma is there because of the way that the cell is formatted; it is not really in the cell itself. Such commas are not counted.

Of course, if all you need to do is know the number of commas and you don't need the value in your worksheet, you can bypass the use of formulas and macros all together. Follow these general steps:

  1. Select the range of cells in which you want to count commas.
  2. Press Ctrl+H to display the Replace tab of the Find and Replace dialog box.
  3. In the Find What box, enter a comma.
  4. In the Replace With box, enter a comma.
  5. Click Replace All.

Excel does the replacement and displays a dialog box that shows how many replacements were made.
