Excel 101: IF, AND, OR Functions and Conditional Logic Explained

You studying this tells me you want to be taught extra about Excel. This text continues our Excel collection, the place we explored the VLOOKUP operate within the final iteration. The whole VLOOKUP information demonstrated how the operate works and the way finest to make use of it. This time, we will deliver the identical focus to conditional logic and formulation just like the IF operate in Excel. The goal is to know the various kinds of conditional logics and know methods to use their operators in a working operate inside Excel.

So, no fluff wanted right here. Let’s merely dive in, beginning with what Conditional Logic in Excel is.

What’s Conditional Logic in Excel?

Conditional logic in Excel means making selections based mostly on a situation. In easy phrases, Excel checks a rule you outline, evaluates the end result, after which performs an motion based mostly on that consequence.

For instance, suppose you could have college students’ marks in a sheet and wish to establish whether or not a scholar has handed or failed. Quite than checking every worth manually, you possibly can merely apply a situation: if the marks are 40 or above, return “Go”; in any other case, return “Fail”. That’s conditional logic in motion.

The identical logic is used throughout many real-world duties in Excel. You would possibly wish to mark gross sales above a goal as “Achieved”, classify bills as “Excessive” or “Low”, or establish whether or not a cost is “Pending” or “Accomplished”. In every case, Excel is evaluating a situation and returning an output based mostly on the end result.

On the core of this course of is a straightforward thought:

take a look at a situation > get a TRUE or FALSE end result > use that end result to determine what occurs subsequent.

Such conditional logic is precisely what makes Excel greater than only a spreadsheet for storing knowledge. Its formulation react to values dynamically, slicing down on hours of guide work.

To make this conditional logic work, Excel depends on conditional operators, that are the symbols used to match values. Subsequent, allow us to study conditional operators intimately.

What are Conditional Operators in Excel?

Give it some thought, how precisely will you examine values inside Excel for any conditional logic to work? You will have comparability symbols for various circumstances, like equal (=), better than (>), smaller than (<), and so forth., proper? All such comparability symbols are referred to as conditional operators in Excel. In essence, these are used to check whether or not a situation is true or false. They’re the constructing blocks behind conditional logic, as a result of they permit Excel to match values earlier than a operate decides what to return.

In easy phrases, these operators assist Excel reply questions like:

Is that this worth better than 50?

Is that this cell equal to “Sure”?

Are these two values completely different?

Has the goal been met or not?

Excel helps six primary conditional operators:

`=` : equal to

`>` : better than

`<` : lower than

`>=` : better than or equal to

`<=` : lower than or equal to

`<>` : not equal to

Allow us to perceive this with a easy instance. Suppose cell `A2` comprises the worth `75`.

=A2>50

Excel checks whether or not 75 is larger than 50. Since that situation is true, the components returns `TRUE`.

Now take a look at this:

=A2<50

This time, Excel checks whether or not 75 is lower than 50. Since that isn’t true, the result’s `FALSE`.

That `TRUE` or `FALSE` output is what powers conditional formulation in Excel. Capabilities like `IF`, `IFS`, `AND`, and `OR` depend on these comparisons to make selections.

For instance:

=IF(A2>=40,”Go”,”Fail”)

Don’t fear, we’ll be taught in regards to the IF operate intimately shortly. For now, simply notice on this instance that Excel first checks whether or not the worth in `A2` is larger than or equal to 40. If the situation is true, it returns `Go`. If the situation is fake, it returns `Fail`. Extra importantly, notice that even the IF operate begins with a conditional operator.

So, whereas features like `IF` usually get all the eye, the actual decision-making begins with these operators. They’re what inform Excel methods to consider a situation within the first place.

Now that the operators are clear, the subsequent step is to know the conditional features during which they’re used, beginning with the `IF` operate.

IF Operate in Excel

The IF operate is likely one of the most generally used formulation in Excel. In its most simple sense, it checks whether or not a situation is true or false, after which returns a end result based mostly on that consequence. In easy phrases, it tells Excel: if this occurs, do that; in any other case, do this.

To grasp it correctly, allow us to break it into two elements.

IF Operate Syntax

The syntax of the IF operate is:

=IF(logical_test, value_if_true, value_if_false)

Right here, every half has a selected function:

logical_test is the situation Excel checks

value_if_true is the end result returned if the situation is true

value_if_false is the end result returned if the situation is fake

Allow us to take a look at a easy instance:

=IF(A2>=40,”Go”,”Fail”)

Here’s what Excel is doing on this components:

It first checks whether or not the worth in cell A2 is larger than or equal to 40

If that situation is true, Excel returns Go

If that situation is fake, Excel returns Fail

So, if A2 comprises 65, the end result will probably be Go. If it comprises 28, the end result will probably be Fail.

That is the essential construction of each IF components. First, Excel evaluates the situation. Then it decides which end result to return.

Forming the Components

Now that the syntax is obvious, the subsequent step is to really construct the components in Excel.

Suppose you could have marks listed in column A, and also you wish to present the lead to column B.

Begin by clicking the cell the place you need the output to look. Then sort:

=IF(A2>=40,”Go”,”Fail”)

Press Enter, and Excel will immediately return the end result based mostly on the worth in A2.

Because the worth meets the situation on this case, you get ‘Go’. If it didn’t, you’d get ‘Fail’.

As soon as the components works in a single cell, you possibly can drag it down to use the identical logic to the remainder of the rows. Excel will mechanically alter the cell reference for every row.

As an example:

in row 2, Excel checks A2

in row 3, it checks A3

in row 4, it checks A4

That is what makes the IF operate so helpful. You create the logic as soon as, and Excel repeats it throughout the dataset in seconds.

Now that we perceive how a single IF components works, the subsequent step is to see what occurs when there are greater than two attainable outcomes. That’s the place Nested IF statements are available.

Nested IF Statements in Excel

A single `IF` operate works nicely when there are solely two outcomes. However many actual Excel duties contain greater than only a yes-or-no determination. You might have to assign grades, label efficiency bands, or categorise values into a number of teams. That’s the place Nested IF statements are available.

A Nested IF merely means inserting one `IF` operate inside one other, so Excel can take a look at a number of circumstances one after the opposite.

Nested IF Syntax

Think about a easy Excel sheet that has the marks of scholars saved as knowledge, and you need to grade the scholars based mostly on their marks. A primary Nested IF components for a similar will look one thing like this:

=IF(A2>=90,”A”,IF(A2>=75,”B”,IF(A2>=40,”C”,”Fail”)))

This may occasionally look intimidating at first, however the logic is simple. Excel checks every situation in sequence:

If `A2` is 90 or above, it returns `A`

If not, it checks whether or not `A2` is 75 or above, and returns `B`

If not, it checks whether or not `A2` is 40 or above, and returns `C`

If none of those circumstances are met, it returns `Fail`

So if `A2` comprises 82, the components returns `B`. If it comprises 36, Excel returns `Fail`.

The important thing factor to know right here is that Excel stops as quickly because it finds the primary true situation. It doesn’t hold checking the remainder.

Forming the Components

Suppose you could have scholar marks in column `A`, and also you wish to assign grades in column `B`.

Click on the output cell and enter:

=IF(A2>=90,”A”,IF(A2>=75,”B”,IF(A2>=40,”C”,”Fail”)))

Then press Enter.

Excel will consider the circumstances from left to proper and return the proper grade for that row. As soon as the components works, drag it down to use the identical grading logic to the remainder of the info, as seen within the picture beneath.

One necessary factor to recollect: the order of circumstances issues. Within the instance above, the very best rating vary is checked first. Should you reverse the order carelessly, Excel could return the improper end result.

Nested IF statements are helpful, however they will develop into troublesome to learn when too many circumstances are concerned. That’s precisely why Excel launched a cleaner various referred to as `IFS`.

IFS Operate in Excel

Think about if, within the grading instance above, you had grades as much as Z handy out. The Nested `IF` statements could get the job carried out, however will certainly develop into very messy, in a short time. When you begin stacking a number of circumstances inside each other, the components turns into tougher to learn, tougher to edit, and simpler to interrupt. That’s the place the `IFS` operate helps.

The `IFS` operate is designed to check a number of circumstances in a cleaner format. As a substitute of nesting one `IF` inside one other, you record every situation and its lead to sequence.

IFS Operate Syntax

The syntax of the `IFS` operate is:

=IFS(logical_test1, value_if_true1, logical_test2, value_if_true2, …)

Every logical take a look at is adopted by the end result Excel ought to return when that situation is true.

Allow us to take the identical grading instance we utilized in Nested IF:

=IFS(A2>=90,”A”,A2>=75,”B”,A2>=40,”C”,A2<40,”Fail”)

Here’s what Excel does:

If `A2` is 90 or above, it returns `A`

If not, it checks whether or not `A2` is 75 or above, and returns `B`

If not, it checks whether or not `A2` is 40 or above, and returns `C`

If `A2` is beneath 40, it returns `Fail`

The logic is much like Nested IF, however the construction is way cleaner. You do not need to maintain observe of a number of closing brackets inside brackets.

Forming the Components

Suppose marks are listed in column `A`, and also you need grades in column `B`.

Click on the output cell and kind:

=IFS(A2>=90,”A”,A2>=75,”B”,A2>=40,”C”,A2<40,”Fail”)

Then press Enter.

Excel will take a look at the circumstances so as and return the end result for the primary situation that evaluates to true. After that, you possibly can drag the components down for the remainder of the rows.

This makes `IFS` particularly helpful when you could have a number of attainable outcomes and need the components to remain readable.

That mentioned, `IFS` is finest if you find yourself checking a number of separate circumstances. However typically the problem just isn’t a number of outcomes. Generally you wish to take a look at multiple situation on the identical time. For that, Excel makes use of `AND` and `OR` features.

AND and OR Capabilities in Excel

To date, we’ve got checked out formulation the place Excel checks one situation at a time. However in actual spreadsheets, a single situation is commonly not sufficient. It’s your decision a end result solely when a number of circumstances are true, or when at the least one out of a number of circumstances is true. That is the place `AND` and `OR` are available.

Each are logical features in Excel, and they’re normally used inside formulation like `IF`.

AND Operate Syntax

The `AND` operate returns `TRUE` solely when all circumstances are true.

Its syntax is:

=AND(logical1, logical2, …)

Allow us to say a scholar passes provided that they rating greater than 40 in principle and greater than 40 in sensible.

=AND(A2>40,B2>40)

Right here, Excel checks each circumstances:

Is `A2` better than 40?

Is `B2` better than 40?

If each are true, Excel returns `TRUE`. If even one is fake, Excel returns `FALSE`.

Now allow us to use it inside an `IF` operate:

=IF(AND(A2>40,B2>40),”Go”,”Fail”)

This tells Excel to return Go provided that each circumstances are glad. In any other case, it returns Fail.

OR Operate Syntax

The `OR` operate works in a different way. It returns `TRUE` when at the least one situation is true.

Its syntax is:

=OR(logical1, logical2, …)

Suppose a salesman qualifies for a bonus in the event that they both cross a gross sales goal or herald a brand new consumer.

=OR(A2>=100000,B2=”Sure”)

Right here, Excel checks:

Is `A2` better than or equal to 100000?

Is `B2` equal to “Sure”?

If even one in every of these is true, Excel returns `TRUE`.

Used inside `IF`, it turns into:

=IF(OR(A2>=100000,B2=”Sure”),”Bonus Eligible”,”Not Eligible”)

So if the individual meets both one of many circumstances, Excel marks them as Bonus Eligible.

Forming the Components

The best option to construct these formulation is to first determine your logic clearly.

Use `AND` when each situation have to be met.

Use `OR` when only one situation is sufficient.

For instance, if an worker will get approval solely after they have accomplished coaching and submitted paperwork, you’d write:

=IF(AND(A2=”Sure”,B2=”Sure”),”Permitted”,”Pending”)

But when they will qualify via both of two routes, you’d use:

=IF(OR(A2=”Sure”,B2=”Sure”),”Permitted”,”Pending”)

That’s the core distinction. `AND` is stricter. `OR` is extra versatile.

These features develop into particularly highly effective when mixed with `IF`, as a result of they permit Excel to deal with extra lifelike decision-making guidelines. However even then, formulation can nonetheless break if the info throws an error. That’s the place `IFERROR` and `IFNA` develop into helpful.

IFERROR and IFNA in Excel

Even when your logic is appropriate, Excel formulation don’t all the time return clear outcomes. Generally they produce errors as a result of a worth is lacking, a lookup fails, or the components can not course of the enter. That’s the place `IFERROR` and `IFNA` develop into helpful.

These features enable you to substitute ugly error messages with one thing extra significant and readable. As a substitute of exhibiting `#VALUE!`, `#DIV/0!`, or `#N/A`, you possibly can ask Excel to return a customized output.

IFERROR Operate Syntax

The `IFERROR` operate checks whether or not a components returns any error. If it does, Excel reveals the worth you specify as a substitute.

Its syntax is:

=IFERROR(worth, value_if_error)

Right here:

`worth` is the components or expression Excel ought to consider

`value_if_error` is what Excel ought to return if the components leads to an error

Allow us to take a look at an instance:

=IFERROR(A2/B2,”Error in Calculation”)

Right here, Excel tries to divide `A2` by `B2`.

If the division works, Excel returns the precise end result

If the components throws an error, resembling division by zero, Excel returns Error in Calculation

That is helpful as a result of it retains your worksheet cleaner and simpler to know.

Forming the IFERROR Components

Suppose you’re calculating share development, and there’s a probability that the earlier worth is zero. A standard division components could return an error. To keep away from that, you possibly can wrap the components inside `IFERROR`:

=IFERROR((B2-A2)/A2,”Not Accessible”)

Press Enter, and Excel will both present the expansion worth or return **Not Accessible** if the components breaks.

This helps loads in stories and dashboards, the place error values could make the sheet look messy or complicated.

IFNA Operate Syntax

The `IFNA` operate is extra particular. It solely handles the `#N/A` error, which normally seems when a lookup components can not discover a match.

Its syntax is:

=IFNA(worth, value_if_na)

Allow us to take a easy instance with `VLOOKUP`:

=IFNA(VLOOKUP(E2,A2:C10,2,FALSE),”Not Discovered”)

Right here, Excel tries to search out the worth from `E2` contained in the vary `A2:C10`.

If a match is discovered, it returns the corresponding end result

If no match is discovered and Excel produces `#N/A`, it returns Not Discovered

That is higher than exhibiting `#N/A` to the reader, particularly in lookup-based sheets.

Forming the IFNA Components

Suppose you could have a product ID in cell `E2`, and also you wish to fetch the product title from a lookup desk. If the ID doesn’t exist, you do not need Excel to indicate an error.

So as a substitute of writing solely:

=VLOOKUP(E2,A2:C10,2,FALSE)

you possibly can write:

=IFNA(VLOOKUP(E2,A2:C10,2,FALSE),”Product Not Discovered”)

This makes the output far more user-friendly.

IFERROR vs IFNA

The distinction is easy:

`IFERROR` handles all sorts of errors

`IFNA` handles solely the `#N/A` error

So in case you are coping with lookups and solely wish to catch lacking matches, `IFNA` is extra exact. However if you need a broader security web for any error, `IFERROR` is the higher alternative.

At this level, we’ve got lined the important thing Excel features that energy conditional logic: `IF`, Nested `IF`, `IFS`, `AND`, `OR`, `IFERROR`, and `IFNA`. The ultimate step is to deliver all the things along with a sensible conclusion on when to make use of every one.

Conclusion

As you begin utilizing these formulation in your Excel sheets extra usually, you’ll realise the period of time every of those can prevent. These features are what make Excel really feel like a working determination system. As a substitute of simply storing numbers and textual content, Excel can consider circumstances, apply guidelines, and return the best solutions mechanically. Therefore, these formulation like `IF`, `IFS`, `AND`, `OR`, `IFERROR`, and `IFNA` have a lot sensible worth.

To sum up, the `IF` operate is the start line while you want Excel to decide on between two outcomes. Nested `IF` helps when these outcomes improve. `IFS` gives a cleaner option to deal with a number of circumstances with out turning the components right into a bracket jungle. `AND` and `OR` take the logic additional by permitting you to check a number of circumstances collectively, relying on whether or not all or simply one in every of them must be true. Lastly, `IFERROR` and `IFNA` assist make your spreadsheets extra readable by changing error messages with helpful outputs.

Since they’ve such excessive sensible worth, the actual good thing about studying these features is the power to make spreadsheets smarter, cleaner, and way more helpful in actual work. When you perceive how conditional logic works, you realise the ability of Excel on the subject of deciphering knowledge.
