For more detail, here is the Excel help file that describes Vlookup( ):
Vlookup( ) searches for a value in the leftmost column of a
table, and then returns a value in the same row from a column you specify in the table.
Use VLOOKUP instead of HLOOKUP when your comparison values are located in a column to the
left of the data you want to find.
Syntax
VLOOKUP(lookup_value,table_array,col_index_num,range_lookup)
Lookup_value is the value to be found in the first column of the array.
Lookup_value can be a value, a reference, or a text string.
Table_array is the table of information in which data is looked up. Use a
reference to a range or a range name, such as Database or List.
· If range_lookup is TRUE, the values in the first column of
table_array must be placed in ascending order: ..., -2, -1, 0, 1, 2, ..., A-Z, FALSE,
TRUE; otherwise VLOOKUP may not give the correct value. If range_lookup is FALSE,
table_array does not need to be sorted.
· You can put the values in ascending order by choosing the Sort
command from the Data menu and selecting Ascending.
· The values in the first column of table_array can be text, numbers,
or logical values.
· Uppercase and lowercase text are equivalent.
Col_index_num is the column number in table_array from which the matching
value must be returned. A col_index_num of 1 returns the value in the first column in
table_array; a col_index_num of 2 returns the value in the second column in table_array,
and so on. If col_index_num is less than 1, VLOOKUP returns the #VALUE! error value; if
col_index_num is greater than the number of columns in table_array, VLOOKUP returns the
#REF! error value.
Range_lookup is a logical value that specifies whether you want VLOOKUP
to find an exact match or an approximate match. If TRUE or omitted, an approximate match
is returned. In other words, if an exact match is not found, the next largest value that
is less than lookup_value is returned. If FALSE, VLOOKUP will find an exact match. If one
is not found, the error value #N/A is returned.
Remarks
· If VLOOKUP can't find lookup_value, and range_lookup is TRUE, it uses
the largest value that is less than or equal to lookup_value.
· If lookup_value is smaller than the smallest value in the first
column of table_array, VLOOKUP returns the #N/A error value.
· If VLOOKUP can't find lookup_value, and range_lookup is FALSE,
VLOOKUP returns the #N/A value.
Examples
On the preceding worksheet, where the range A4:C12 is named
Range:
VLOOKUP(1,Range,1,TRUE) equals 0.946
VLOOKUP(1,Range,2) equals 2.17
VLOOKUP(1,Range,3,TRUE) equals 100
VLOOKUP(.746,Range,3,FALSE) equals 200
VLOOKUP(0.1,Range,2,TRUE) equals #N/A, because 0.1 is less than the smallest value in
column A
VLOOKUP(2,Range,2,TRUE) equals 1.71
