To find the highest value in a column combine VLOOKUP and MAX as shown below. You can do the same with MIN to find the lowest value in a column. In this example you can also use the value in Sales to find the Salesperson simply by changing the column from 1 to 2.
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
Lookup Value A2:A9
Table Array A2:B9
Sales - Column Index 1
Salesperson - Column Index 2
Range Lookup - True = 0, False = 1
Sales Salesperson

$901 =VLOOKUP(MIN(A2:A19),A2:B9,1,0)
$10,146 =VLOOKUP(MAX(A2:A19),A2:B9,1,0)
Ronald Gardner =VLOOKUP(MIN(A2:A19),A2:B9,2,0)
Louis Carpenter =VLOOKUP(MAX(A2:A19),A2:B9,2,0)
