Barry often finds himself wanting to identify the Nth occurrence of a character within a text string. He knows he can use the SEARCH and FIND worksheet functions for finding an initial occurrence, but is unsure how to find, say, the 3rd occurrence of the letter "B" within a text string.

Actually, the SEARCH function could be used to find the desired occurrence, in the following manner:

=SEARCHB("b",G20,(SEARCHB("b",G20,(SEARCHB("b",G20,1)+1))+1))

Notice how the SEARCHB function is used in a nested manner. The formula specifies what is being searched for (the letter "b") and the number of nesting levels indicates which occurrence within the cell you want to find. The formula returns the position of the desired character within the cell.

The problem with such a formula, of course, is that it is difficult to maintain and can quickly get unusable if you want to find, say, the seventh occurrence.

A more flexible formula would be the following:

=FIND(CHAR(1),SUBSTITUTE(A1,"B",CHAR(1),3))

This formula examines the value in A1. It substitutes the CHAR(1) code for the third occurrence of "B" within the cell. The FIND function then looks within the resulting string for the position where CHAR(1) occurs. If the desired occurrence does not exist, then the formula returns a #VALUE error.

If you prefer, you could create a user-defined function that will look for the Nth position of a character. The following is a very simple macro that takes three arguments: the string to be searched, the text to match, and the position desired.

Function FindN(sFindWhat As String, _ sInputString As String, N As Integer) As Integer Dim J As Integer Application.Volatile FindN = 0 For J = 1 To N FindN = InStr(FindN + 1, sInputString, sFindWhat) If FindN = 0 Then Exit For Next End Function

The function is case sensitive in what it searches for, and it returns the position within the specified string at which the sFindWhat value occurs. If there is no occurrence at the specified instance, then the function returns a 0. The following shows how the function can be used in a worksheet:

=FindN("b",C15,3)

Hello,

I'm working with two large spread sheets that consist of account numbers that can have multiple duplicates. I want to retrieve the Codes that I'm doing a V-lookup on to show the many different type of services that were done. When I Google my request normally the formulas consist of one single tab with an array of no more than 10 to keep it simple. Can anybody give me an example of two different spread sheets and how to select the data in a vlookup format and or index to retrieve the value desired??

As a note, =FIND(CHAR(1),SUBSTITUTE(A1,"B",CHAR(1),3))

in Google Sheets, this does not work for char's that are non-printable characters like char(1). I went with char(239) and that seems to work.

This much shorter UDF for your FindN function works in XL2003 (the earliest version I own) but I think should work in the earlier versions of Excel covered by this article as well...

Function FindN(sFindWhat As String, sInputString As String, N As Long) As Long

Application.Volatile

FindN = InStr(Replace(sInputString, sFindWhat, " ", 1, N - 1), sFindWhat)

End Function

Function FindN(sFindWhat As String, sInputString As String, N As Long) As Long

Application.Volatile

FindN = InStr(Replace(sInputString, sFindWhat, " ", 1, N - 1), sFindWhat)

End Function

...Sorry,

Didn't noticed the: =FIND(CHAR(1),SUBSTITUTE(A1,"B",CHAR(1),3))

formula.

@To whom it may concern,

There is a much shorter and simpler formula to identify the place of the 3rd occurrence of the letter "B":

=FIND("|",SUBSTITUTE(A1,"B","|",3))
