Search for best match with strings

Hy everyone,

I was looking for AddIns and macros to find a way to search and find the best match with strings. But no luck. Can you please help me?
In column A are different strings. Take the first (A2) and search for the best result that matches in Column E. Then copy the best result after searching to B2
and show the percentage of matching. Then take A3 and do the same again.
I guess this is a big thing to do, but thanks for your help.

Kind Regards
Roman
