First, lets look at our sales data. You might recognize this from a previous exercise.

What you are looking for is a simple table as follows, so you can start learning more who your best customers are, and some of their buying habits.

Let’s see which functions will give us the right information for each column:

If you start writing =SumIf( in Excel, a tooltip will appear which gives you a reminder of how to use this formula.

The first part you will need to fill out is the **range**. In this case, the range will can be thought of as “Where do you want to look for this customer name?”, the answer being column C, which in Excel you can either click the column C header to select it, or write C:C. Let’s click the column header to select it:

Also notice how the formula updated.

The second section we have to fill is the **criteria**. The criteria is what you are trying to match, which in this case is Customer 1, which is found in cell I2, so we will select I2.

Last but not least, we need to tell Excel what we need to sum, the **sum range**, which in this case would be the amounts found in column D.

Congratulations, you know know how to use SumIf!. If you close the parenthesis ) of the formula and press enter, you will see how much Customer1 has purchased:

One of my favourite features of Excel is the ability to drag a formula down to copy it quickly over a range. Select the cell containing your SumIf formula, and then click and hold your left mouse button on the the little dot in the bottom right of that cell.

While keeping your left mouse button pressed down, move your mouse cursor down over the area you would like to copy this formula to.

Release the left mouse button, and you will see the formula copied itself over making adjustments as needed so the formula in cell J3 is matching the content in cell I3, etc.

To find out how many times each customer placed an order, we will use the CountIf formula, which counts how many times some text appears in your selection. This formula is a little simpler than the other two, having only two sections: a range, and a criteria.

The first step consists in writing =countif( to see the Excel tooltip.

The **range** comes first, which is where you want to look for a match, which in this case would be column C. You can either select column C, or write C:C in the formula bar.

Next up is the **criteria** which is what we are trying to match, which in this case would be the content of cell I2.

Closing the parenthesis ), pressing enter, and then using the dragging technique from before, we get the number of purchases per customer.

To obtain the average sales amount per order, we have two options. Since we already calculated the sum of the amounts and the count of orders, we could simply go in cell L2 and type =J2/K2. But since this is a tutorial, let’s use this exercise as an excuse to learn AverageIf, that way you don’t have to use SumIf and CountIf if all you’re looking for is the average.

As usual, type =averageif( in a cell will give you the tooltip on how to use this tool. If you look at the 3 arguments of this formula: **range**, **criteria**, and **average range**, you’ll notice this follows the same structure as the SumIf() formula we have just seen.

Using a **range** of column C, a **criteria** of cell I2, and an **average range** of column D, we get the following formula:

Using the same drag-down technique as before, we get the average sales per customer.

The Sum formula is a great one to start with. Excel formulas all start with an = sign, followed by the function name and a section in parentheses to provide ranges or arguments. Start out by typing =sum(

Sum requires a range of cells you want to add together. You can type your range in, or you can select it using your mouse or input device. In this case, we will select D2:D21.

Next up you can close the parenthesis, although newer versions of Excel will auto close it for you.

Using the same method, you can calculate the average, minimum value, maximum value, and count:

Which if you were using the downloadable exercise workbook, will give you the following results:

Here are some basic formulas, and what they do.

Sum | Adds all the cells together and gives you the total sum. |

Average | Gives you the average of the selection you provide. |

Min | Returns the smallest value from the selection you provide. |

Max | Returns the largest value from the selection you provide. |

Count | Counts how many cells have values in them. |

- In the bottom right of the screen, newer versions of Excel provide you with a Sum, Average, and Count by default, and can be configured by right-clicking on it to provide minimum, maximum, and numerical count.

As an example of how the Excel Vlookup function works, let’s take a simple excel workbook with the following two tabs: Orders and Customers.

The Orders tab contains an order number, date, customer name, and amount.

We want to add the Country, City, and Phone number of each customer, which thankfully we have in the Customers tab.

By using the Excel VLOOKUP function, we can quickly and efficiently fill in the Country, City, and Phone in the Orders tab.

Let’s go back to the Orders tab, and start typing the =vlookup( formula to see the tooltip provided by Microsoft:

If you’ve never used the Excel vlookup function before, this provides absolutely no help. But lets break it down in an easier way:

Argument |
Description |
Example |
Example Code |

lookup_value |
The value which is in common between both tables | In this case, Customer Name, more specifically, if we are trying to find the Country for the customer on line two (i.e. we are trying to fill cell E2), we would select cell C2 as the customer name. | C2 |

tabble_array |
Where the information you are looking for is located. The first column should contain the common element, and the range should be large enough to include | In this case, it would be the Customers tab, columns A through D. | Customers!A:D |

col_index_num |
Based on the range you put in table_array, the col_index_num is the number of the column which contains the result you are looking for. For example, if you selected A:D as your range, and the common element is in column A, and the result is in column B, you would put 2 as your column number. Putting 3 would give you the result from column C, and putting 4 would give you the result from column D. However, if you select L:P as your range, then column 1 is L, column M is 2, column N is 3, etc. | Because the country code is located in column B of the Customers tab, we will select 2 | 2 |

[range_lookup] |
Last and definitely not least, the range_lookup gives you a true or false option. False will only return an exact match, while True will try to look for a result which looks similar to what you are looking for. 99%+ of the time I find False to be the best option to use. For example, if you had an order for Customer8, because there is no Customer8 in the customers tab, using false would return #N/A meaning Excel could not find a match. This would let you know that you have to add Customer8 to the Customers tab. If you select true, that same Customer8 would return United States, because Customer8 looks similar to Customer7, which is in the US. | false |

We end up with the following formula: *=VLOOKUP(C2,Customers!A:D,2,FALSE)*, where C2 is the Customer we are trying to match up, Customers!A:D contains the customer information we want to look into, 2 is the 2nd column from that range, and False because we only want exact matches.

Using the same method, we can create the formulas for F2 and G2 by changing the 2 to a 3 or a 4. (I changed my view settings in Excel to show the formulas instead of the values, so you should see Canada, Ottawa, and (555) 555-0001 instead of the formulas)

You can then select a formula and drag the little dot in the corner to fill in the other formulas very quickly:

Which would give us the following formulas (again in formula view):

Here is what you should see on your screen at the end. By using the formula dragging feature, you can very quickly perform vlookups for thousands of records!

- Using full columns as your range, for example A:D instead of A2:D7, makes it easier to add/remove items from your table without having to change the 2 and 7 all the time.
- If you do use a range such as A2:D7, remember that if you drag your formula down, you will get A3:D8, A4:D9, etc, and if you drag your formula right, you will get B2:E7, C2:F7, etc. The easiest way to prevent this is to use $ signs to make sure the range doesn’t change, such as $A$2:$D$7.
