Hi Neil,

Perhaps a formula in a helper column and pull down. Then copy and paste
special values to get rid of the formulas.

Assumes all are nn:nn:nn to start with, 8 characters.

=LEFT(E1,5)&"."&RIGHT(E1,2)

Hi

I have some numbers denoted thus:-

02:34:56 (they can be any numbers at all separated by Colons

and I want to replace the last Colon with a dot/period so it is

02:34.56

I tried to replace using **:**:** to **:**.** but it fills in with the
latter

How can I achieve please

Neil
