Today, I decided to look at the excel function AND. What does it do exactly? First, I would like to clarify that there are two main ways you would use the “AND” function. You can either use it in a nested if statement or you can use by itself. You might not understand what I mean but I will explain this much more clearly with examples.

**Why You Would Use The Excel AND Function**

There are many different ways to use the “AND” function. Basically, it is used to verify if a number of conditions are ALL met at once. It’s important to understand this. The objective of the function is to verify that all conditions are met. You could use 2 5 or even 10 conditions to verify. If only one of those is false, the function will return a negative value.

**How Do I Use The And Function?**

The first question to ask yourself is: “What type of value do you need the function to return?”

Basically you have two options:

#1-The function will return “TRUE” (if all conditions are met) or “FALSE” (if at least 1 condition is not met)

#2-You can decide what the function will return in both cases

The solution #1 only requires the use of “AND” while the solution #2 uses a nested function “IF(AND)”. If ever you are interested in reading more about nested functions in excel, you can visit a post we wrote about it here. Obviously, the second one is much more flexible and that is the one I would normally use. However, let’s start with a quick example of the “AND” function.

If I had this table of rankings and wanted to easily see which players are Russian, have played under 20 tournaments and whose name is less than 18 characters, here is what I could do:

AND (condition #1, condition #2, condition #3)

In this case, I would do:

=AND(E2=”RUS”,G2<20,LEN(C2)>18)

You can see the result here and in fact I could use conditional formatting to make it even more obvious:

Let’s imagine however that I would want to use either a formula or change the way the information is presented. Then, it would be easier to do an “IF AND” excel function as follows:

=IF(AND(E2=”RUS”,G2<20,LEN(C2)>18),”OK”,””)

As you can see, the difference is very small between the two so I think in most cases, it makes a lot more sense to use the “If And” function.
