That's not an option in VLOOKUP, if you use FALSE as the final parameter, it
will find exact matches only, and if you use TRUE it will drop down to the
closest match. There isn't a round UP option.
But you could use an INDEX(MATCH) function and trick it into doing that, but
it might get weird when there IS an exact match.
If the data you want to return is in column B based on a lookup of a value
in column A and you want it to find the closest match and round up, you have
to offset the ranges by one row to trick it into doing that. I'm putting the
value to match in C1
=INDEX($B$2:$B$101,MATCH(C1,$A$1:$A$100,1))
That will do what you want when there ISN'T an exact match. If there is
won't get the right answer. So you probably need to do a test first.
=IF(ISNA(MATCH(C1,$A$1:$A$100,0)),
INDEX($B$2:$B$101,MATCH(C1,$A$1:$A$100,1)),
INDEX($B$1:$B$100,MATCH(C1,$A$1:$A$100,0)))
Hope that gets you closer.
