Hi,

I know there are methods to find the closest match to a number that is
either greater than or smaller than a reference number but how do you
find the closest number regardless of whether its larger or smaller.

Any help would be very welcome.

Regards
Andy.
 
Assuming there are no duplicates in your list,
enter as an array formula
=SUMPRODUCT(((ABS(list-target))=MIN(ABS(list-target)))*list)
otherwise use this array formula for the first closest match
=INDEX(list,MATCH(MIN(ABS(list-target)),(ABS(list-target)),0))
