Selecting a list of numbers from a longer one

[mass]

Hi, I really need help on this
I have a long list of:
item codes; description in next column; and then quantity in third
column.

I have another shorter list of item codes with data associated.

How can I sort through the first list to find all of the second list
without doing it one by one?
Thanks for any help.

If you have the long list on sheet1 and the short list on sheet2, you could use
an extra column and a formula like:

=isnumber(match(a1,sheet2!a:a,0))

This will return True if A1 was in column A of Sheet2.

If you decide you want to return the data from that shorter list, you could use
a formula like:

=vlookup(a1,sheet2!a:b,2,false)

(return what's in column B when there's a match in column A.)
