Finding position of last period in filename
 

I have a large spreadsheet of filenames. I'm trying to break the
names into Filename and File extension using LEFT and RIGHT functions.
I'm having trouble getting some of these names because some of the
filenames contain more than one period,

eg., This.is.the.filename.DOC is in Col A.

Can someone suggest a function that would separate both parts?

This.is.the.filename in Col B
DOC in Col C.

Thanks in advance.

Three functions (filename in A5)...
=SUBSTITUTE(RIGHT(SUBSTITUTE(A5,".",REPT(".",99)), 99),".","")

B1: =LEFT(A1,FIND(CHAR(1),SUBSTITUTE(A1,".",CHAR(1),LE N(A1)-LEN(SUBSTITUTE(A1,".",""))))-1)

C1: =TRIM(RIGHT(SUBSTITUTE(A1,".",REPT(" ",99)),99))

B1:
=LEFT(A1,FIND(CHAR(1),SUBSTITUTE(A1,".",CHAR(1),LE N(A1)-LEN(SUBSTITUTE(A1,".",""))))-1)

C1: =TRIM(RIGHT(SUBSTITUTE(A1,".",REPT(" ",99)),99))

Perhaps, since we know what C1 will contain, this simpler formula for B1...

B1: =SUBSTITUTE(A1,"."&C1,"")

I don't like that because it fails if the suffix happens to also exist within the first part of the extract.

e.g.:

A1: This.is.the.DOCument.filename.DOC

Both solutions work perfectly. Thanks again.
