You can return the last numeric value in a column when you use an extremely large number as the lookup value (to be sure that it will be larger than any number) and 9E+100 is an EXTREMELY LARGE number, it a 9 with 100 zero behind it. Almost a Googol number https://en.wikipedia.org/wiki/Googol
=VLOOKUP(9E+100
... for numeric to return the last value
I would ad when searching for the last text value a series of "zzzzzzz" will have the same effect for text than 9E+100 for numerics
=VLOOKUP( "zzzzzzz".... for text to return the last value
