Searching a column to a match of a given cell

Question

I have a column that I need to compare against another column.

If the content of my column are in the other column I need to return true.

Here is what I tried but it isn't working, it only seems to work if they are on the exact same line.

=OR(EXACT(F2, $B$2:$B$595))

F column is the cell I need to search from, B2 thru B595 are what I need to see if F is in.

Column B     Column F      True/False
abc           1234          TRUE
bbc           1675          FALSE
1234

Answer 1

=NOT(ISERROR(MATCH(F2,$B$2:$B$595,0)))

Answer 2

Just as an alternate to MATCH , you could also use VLOOKUP function.

Column B  Column F  Column G
abc       1234      =NOT(ISERROR(VLOOKUP(F1,$B$1:$B$595,1,FALSE))) // TRUE
bbc       1675      =NOT(ISERROR(VLOOKUP(F2,$B$1:$B$595,1,FALSE))) // FALSE
1234                =NOT(ISERROR(VLOOKUP(F3,$B$1:$B$595,1,FALSE))) // FALSE
