Read this blog that explains the VLOOKUP using the Approximate or TRUE argument ** Note that the LOOKUP function uses the Approximate Match argument automatically (TRUE argument in a VLOOKUP), so therefore the result_vector has to be sorted in ascending order **

=LOOKUP( The value that you want to lookup, Range that contains the values to be lookup up, Range that contains the values to be returned) =LOOKUP( lookup_value, lookup_vector, result_vector)

It looks up a value (lookup_value) in one range (lookup_vector) and returns a value from the same position in a second range (result_vector) The LOOKUP function has three arguments, it is a like a simplified VLOOKUP function: This is double the work! Total Bonus Due With An Array Lookup Formula If we had to get the above result using a non-Array Formula we would have to create a helper column which multiplies UNITS SOLD by UNIT PRICE and then enter the SUM formula to get the same result. STEP 3: Instead of pressing ENTER to evaluate the formula, you need to press CTRL+SHIFT+ENTER to turn the formula into an Array Formula which will look like this: STEP 2: Select the array/range of data for the UNITS SOLD, enter the multiplier sign * and select the array/range of the data for the UNIT PRICE: Let’s do an example of an Array Formula that calculates the Total Sales for various products: Using an Array Formula we skip the “helper column” and just enter one formula only. If we had to calculate Total Sales the normal way, we would have to create a “helper column” for the Totals column and then enter a formula to Sum all the Totals. One of the most popular uses of an array formula is to calculate Total Sales. This could be a range of cells, a worksheet reference or a defined name. This is double the work! Calculate Total Sales With An Array FormulaĪn Array Formula performs an Excel operation (math, comparative, join or function argument) on an array or range of data. If we had to get the above result using a non-Array Formula we would have to create a helper column which subtracts the Open & Close cells and then enter the MAX formula to reference these results. STEP 4:By pressing F9 on the selected formula array will give you the resulting array of numbers (press CTRL+Z to get out of this mode when you are done checking the formula results): STEP 2: Subtract one array/range of data from another array/range of data =MAX( D13:D16– C13:C16)
