VLOOKUP (lookup_value, table_array, col_index_num, [range_lookup])The VLOOKUP, or vertical lookup, searches for a value in the first column of an array and returns a value in the same row from a specified column in the table array. The “lookup_value” is the specified value that the function will lookup within the range. The “lookup array” is the range that the function will use as an absolute reference for the vertical lookup and column index. Note that the vlookup will always use the left most column for the lookup value. Based on the look up value the function will look at the Nth column based on the specified “col_index_num.” To ensure you are looking up the correct value, you will set the “range_lookup” to false.
