I've got some data and I need something like vlookup. I've got a
spreadsheet that I can't change which has the following info:

Col A --- Col B
area ---- plunger diameter
0.01 ---- 60
0.022 --- 120
0.072 --- 400
0.18 ---- 1000
0.45 ---- 2500
0.72 ---- 4000

I need to return a value for the size of plunger needed given a certain
area.

However, vlookup returns the value on the same row, i.e. if I have an
area of 0.015 it returns 60. What I actually need is that for up to
0.01 it returns 60, then for up to 0.022 it returns 120 etc.

I'm sure there's a really simple way of doing it. Currently the only
way I've found to do it is a load of nested IF statements (and if the
data needs extending this can get messy). Is there any way of using
vlookup or something similar.

Thanks in advance.

Rob

Use this table:

area plunger diameter
0,000 60
0,010 120
0,022 400
0,072 1000
0,180 2500
0,450 4000
0,720

Unfortunately I can't change the spreadsheet the data is coming from,
and it's liable to change so I can't just copy the data, I need to link
to it.

So I need to work with the data in its existing format.

Any more suggestions out there?

Rob

With sorted data, you can use vlookup with the True option instead of False.
Have a look in Help for the difference between the two options.

Yes, with false it has to be an exact match.

With true it uses the "nearest" value. Which actually means it carries
on using one value until it comes to the next one (i.e. in this case if
my area is 0.015 it returns 60). I need it to return the next hightest
value once it's gone past the change (i.e. in this case, for area of
0.015 I need it to return 120).

I was hoping that there might be a similar sort of formua or a
different way of using vlookup to do what I want. Any more ideas?

Cheers,

Rob

You could sort the data in descending order.

What about this one (F2 contains the area value to be looked up):
=INDEX(B$2:B$7,IF(F2-0.001<0.01,1,MATCH(F2-0.001,A$2:A$7)+1))
