IF is one of the most popular and useful functions in Excel. You use an IF statement to test a condition and to return one value if the condition is met, and another value if the condition is not met.
In this tutorial, we are going to learn the syntax and common usages of Excel IF function, and then will have a closer look at formula examples that will hopefully prove helpful both to beginners and experienced users.
The IF function is one of logical functions that evaluates a certain condition and returns the value you specify if the condition is TRUE, and another value if the condition is FALSE.
The syntax for IF is as follows:
As you see, the IF function has 3 arguments, but only the first one is obligatory, the other two are optional.
For example, your logical test can be expressed as or B1="sold", B1<12/1/2014, B1=10 or B1>10.
For example, the following formula will return the text "Good" if a value in cell B1 is greater than 10: =IF(B1>10, "Good")
For example, if you add "Bad" as the third parameter to the above formula, it will return the text "Good" if a value in cell B1 is greater than 10, otherwise, it will return "Bad":
=IF(B1>10, "Good", "Bad")
Though the last two parameters of the IF function are optional, your formula may produce unexpected results if you don't know the underlying logic beneath the hood.
If the value_if_true argument is omitted (i.e. there is only a comma following logical_test), the IF function returns zero (0) when the condition is met. Here is an example of such a formula:
=IF(B1>10,, "Bad")
In case you don't want your Excel IF statement to display any value when the condition is met, enter double quotes ("") in the second parameter, like this: =IF(B1>10, "", "Bad")
. Technically, in this case the formula returns an empty string, which is invisible to the user but perceivable to other functions.
The following screenshot demonstrates the above approaches in action, and the second one seems to be more sensible:
If you don't care what happens when the specified condition is not met, you can omit the 3rd parameter in your formulas, which will result in the following.
If the logical test evaluates to FALSE and the value_if_false
parameter is omitted (there is just a closing bracket after the value_if_true
argument), the IF function returns the logical value FALSE. It's a bit unexpected, isn't it? Here is an example of such a formula:
=IF(B1>10, "Good")
Putting a comma after the value_if_true argument forces your IF statement to return 0, which doesn't make much sense either:
=IF(B1>10, "Good",)
And again, the most reasonable approach is to put "" in the third argument, in this case you will have empty cells when the condition is not met:
=IF(B1>10, "Good", "")
For your Excel IF formula to display the logical values TRUE and FALSE when the specified condition is met and not met, respectively, type TRUE in the value_if_true
argument. The value_if_false
parameter can be FALSE or omitted. Here's a formula example:
=IF(B1>10, TRUE, FALSE)
or
=IF(B1>10, TRUE)
If you want "TRUE" and "FALSE" to be usual text values, enclose them in "double quotes". In this case, the returned values will be aligned left and formatted as General. No Excel formula will recognize such "TRUE" and "FALSE" text as logical values.
Instead of returning certain values, you can get your IF formula to test the specified condition, perform a corresponding math operation and return a value based on the result. You do this by using arithmetic operators or other functions in the value_if_true
and /or value_if_false
arguments. Here are just a couple of formula examples:
Example 1: =IF(A1>B1, C3*10, C3*5)
The formula compares the values in cells A1 and B1, and if A1 is greater than B1, it multiplies the value in cell C3 by 10, by 5 otherwise.
Example 2: =IF(A1<>B1, SUM(A1:D1), "")
The formula compares the values in cells A1 and B1, and if A1 is not equal to B1, the formula returns the sum of values in cells A1:D1, an empty string otherwise.
Now that you are familiar with the IF function's syntax, let's look at some formula examples and learn how to use it in reallife scenarios.
The use of the IF function with numeric values is based on using different comparison operators to express your conditions. You will find the full list of logical operators illustrated with formula examples in the table below.
Condition  Operator  Formula Example  Description 
Greater than  >  =IF(A2>5, "OK",) 
If the number in cell A2 is greater than 5, the formula returns "OK"; otherwise 0 is returned. 
Less than  <  =IF(A2<5, "OK", "") 
If the number in cell A2 is less than 5, the formula returns "OK"; an empty string otherwise. 
Equal to  =  =IF(A2=5, "OK", "Wrong number") 
If the number in cell A2 is equal to 5, the formula returns "OK"; otherwise the function displays "Wrong number". 
Not equal to  <>  =IF(A2<>5, "Wrong number", "OK") 
If the number in cell A2 is not equal to 5, the formula returns "Wrong number "; otherwise  "OK". 
Greater than or equal to  >=  =IF(A2>=5, "OK", "Poor") 
If the number in cell A2 is greater than or equal to 5, the formula returns "OK"; otherwise  "Poor". 
Less than or equal to  <=  =IF(A2<=5, "OK", "") 
If the number in cell A2 is less than or equal to 5, the formula returns "OK"; an empty string otherwise. 
The screenshot below demonstrates the IF formula with the "Greater than or equal to" logical operator in action:
Generally, you write an IF statement with text using either "equal to" or "not equal to" operator, as demonstrated in a couple of IF examples that follow.
Like the overwhelming majority of functions, IF is caseinsensitive by default. What it means for you is that logical tests for text values do not recognize case in usual IF formulas.
For example, the following IF formula returns either "Yes" or "No" based on the "Delivery Status" (column C):
=IF(C2="delivered", "No", "Yes")
Translated into plain English, the formula tells Excel to return "No" if a cell in column C contains the word "Delivered", otherwise return "Yes". At that, it does not really matter how you type the word "Delivered" in the logical_test argument  "delivered", "Delivered", or "DELIVERED". Nor does it matter whether the word "Delivered" is in lowercase or uppercase in the source table, as illustrated in the screenshot below.
Another way to achieve exactly the same result is to use the "not equal to" operator and swap the value_if_true and value_if_false arguments:
=IF(C2<>"delivered", "Yes", "No")
If you want a casesensitive logical test, use the IF function in combination with EXACT that compares two text strings and returns TRUE if the strings are exactly the same, otherwise it returns FALSE. The EXACT functions is casesensitive, though it ignores formatting differences.
You use IF with EXACT in this way:
=IF(EXACT(C2,"DELIVERED"), "No", "Yes")
Where C is the column to which your logical test applies and "DELIVERED" is the casesensitive text value that needs to be matched exactly.
Naturally, you can also use a cell reference rather than a text value in the 2^{nd} argument of the EXACT function, if you want to.
If you want to base your condition on a partial match rather than exact match, an immediate solution that comes to mind is using wildcard characters (* or ?) in the logical_test argument. However, this simple and obvious approach won't work. Many functions accept wildcards, but regrettably IF is not one of them.
A solution is to use IF in combination with ISNUMBER and SEARCH (caseinsensitive) or FIND (casesensitive) functions.
For example, if No action is required both for "Delivered" and "Out for delivery" items, the following formula will work a treat:
=IF(ISNUMBER(SEARCH("deliv",C2)), "No", "Yes")
We've used the SEARCH function in the above formula since a caseinsensitive match suits better for our data. If you want a casesensitive match, simply replace SEARCH with FIND in this way:
At first sight, it may seem that IF formulas for dates are identical to IF statements for numeric and text values that we've just discussed. Regrettably, it is not so.
Unlike many other Excel functions, IF cannot recognize dates and interprets them as mere text strings, which is why you cannot express your logical test simply as >"11/19/2014" or >11/19/2014. Neither of the above arguments is correct, alas.
To make the IF function recognize a date in your logical test as a date, you have to wrap it in the DATEVALUE function, like this DATEVALUE("11/19/2014"). The complete IF formula may take the following shape:
=IF(C2<DATEVALUE("11/19/2014"), "Completed", "Coming soon")
As illustrated in the screenshot below, this IF formula evaluates the dates in column C and returns "Completed" if a game was played before Nov11. Otherwise, the formula returns "Coming soon".
In case you base your condition on the current date, you can use the TODAY() function in the logical_test argument of your IF formula. For example:
=IF(C2<DATEVALUE("11/19/2014"), "Completed", "Coming soon")
Naturally, the Excel IF function can understand more complex logical tests, as demonstrated in the next example.
Suppose, you want to mark only the dates that occur in more than 30 days from now. In this case, you can express the logical_test argument as A2TODAY()>30. The complete IF formula may be as follows:
=IF(A2TODAY()>30, "Future date", "")
To point out past dates that occurred more than 30 days ago, you can use the following IF formula:
=IF(TODAY()A2>30, "Past date", "")
If you want to have both indications in one column, you will need to use a nested IF function like this:
=IF(A2TODAY()>30, "Future date", IF(TODAY()A2>30, "Past date", ""))
If you want to somehow mark your data based on a certain cell(s) being empty or not empty, you can either:
The table below explains the difference between these two approaches and provides formula example.
Logical test  Description  Formula Example  
Blank cells  =""  Evaluates to TRUE if a specified cell is visually empty, including cells with zero length strings.
Otherwise, evaluates to FALSE. 
=IF(A1="", 0, 1)
Returns 0 if A1 is visually blank. Otherwise returns 1. If A1 contains an empty string, the formula returns 0. 
ISBLANK()  Evaluates to TRUE is a specified cell contains absolutely nothing  no formula, no empty string returned by some other formula.
Otherwise, evaluates to FALSE. 
=IF(ISBLANK(A1), 0, 1)
Returns the results identical to the above formula but treats cells with zero length strings as nonblank cells. That is, if A1 contains an empty string, the formula returns 1. 

Nonblank cells  <>""  Evaluates to TRUE if a specified cell contains some data. Otherwise, evaluates to FALSE.
Cells with zero length strings are considered blank. 
=IF(A1<>"", 1, 0)
Returns 1 if A1 is nonblank; otherwise returns 0. If A1 contains an empty string, the formula returns 0. 
ISBLANK()=FALSE  Evaluates to TRUE if a specified cell is not empty. Otherwise, evaluates to FALSE.
Cells with zero length strings are considered nonblank. 
=IF(ISBLANK(A1)=FALSE, 0, 1)
Works the same as the above formula, but returns 1 if A1 contains an empty string. 
The following example demonstrates blank / nonblank logical test in action.
Suppose, you have a date in column C only if a corresponding game (column B) was played. Then, you can use either of the following IF formulas to mark completed games:
=IF($C2<>"", "Completed", "")
=IF(ISBLANK($C2)=FALSE, "Completed", "")
Since there are no zerolength strings in our table, both formulas will return identical results:
Hopefully, the above examples have helped you understand the general logic of the IF function. In practice, however, you would often want a single IF formula to check multiple conditions, and our next article will show you how to tackle this task. In addition, we will also explore nested IF functions, array IF formulas, IFEFFOR and IFNA functions and more. Please stay tuned and thank you for reading!

Hi. I am trying to create a formula that compares a single cell to an entire column(unlimited number) of data. Basically I have a tracking # in a cell and need to compare that to a column consisting of tracking #'s that have been shipped(I will be continuously adding to this column). I want to create a column that lets me know if that tracking # in a cell has been shipped.
So I was tried using formula:
=if(C9=I:I,"Shipped","Freezer")
But it doesn't not work. even though that cell(C9) matches a number in I:I, it will not display shipped and only displays freezer instead.
Hello!
The IF function does not work with ranges. Please use the following formula
=IF(ISNUMBER(MATCH(C9,I:I,0)),"Shipped","Freezer")
You can learn more about MATCH function in Excel in this article on our blog.
