Another interpretation:

=INDEX(B1:B99,MATCH(1,--(ABS(B1:B99-A1)=MIN(ABS(B1:B99-A1))),0))

This is an array formula. Hit ctrl-shift-enter instead of enter. If you do it
correctly, excel will wrap curly brackets {} around your formula. (don't type
them yourself.)

Hi

I have a list of numbers in column "B" and I also have a number in cell A1.

I want to get the closest number in column B to the value in A1 using a
formula,
is this possible?

Thanks for your help.
