Here is a way to achieve this effect without using Find/Replace:
1. Highlight your column, then Forman- Cells- Custom
2. the format your cells should be in is hh:mm:ss. In the Type: text box,
change this format to hh:mm.ss

Now, your column should be fixed.

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
