Use INDEX MATCH to find greater than/equal to value

Question

I\'ve been searching online and in Excel Help but cannot find whether this is possible.

Given a list of numbers, values and a search term, I need to find the value w

Answer 1

Your desired results appear a little inconsistent. Why is the desired result for 15 Orange but that for 63 Indigo?

Are you in fact attempting to match based on whichever corresponding value is absolutely closest to the search value, whether below or above that value?

If so:

=INDEX(B4:B10,MATCH(TRUE,INDEX(ABS(A4:A10-B1)=MIN(INDEX(ABS(A4:A10-B1),,)),,),0))

though that still won't differentiate between e.g. Orange and Yellow for a search value of 25 (though I'm not sure how you are considering 25 "closer" to 30 than 20 in any case).

Another method of doing this is to place the numbers and colours into a table, order numbers by highest to smallest and use the formula below:

=INDEX(B4:B10,MATCH(B1,A4:A10,-1))
