Sometimes you need to check if a cell is blank, generally because you might not want a formula to display a result without input.

In this case we’re using IF with the ISBLANK function:

=IF(ISBLANK(D2),»Blank»,»Not Blank»)

Which says IF(D2 is blank, then return «Blank», otherwise return «Not Blank»). You could just as easily use your own formula for the «Not Blank» condition as well. In the next example we’re using «» instead of ISBLANK. The «» essentially means «nothing».

=IF(D3=»»,»Blank»,»Not Blank»)

This formula says IF(D3 is nothing, then return «Blank», otherwise «Not Blank»). Here is an example of a very common method of using «» to prevent a formula from calculating if a dependent cell is blank:

=IF(D3=»»,»»,YourFormula())

IF(D3 is nothing, then return nothing, otherwise calculate your formula).

Explanation

In this example, the goal is to create a formula that will return «Done» in column E when a cell in column D contains a value. In other words, if the cell in column D is «not blank», then the formula should return «Done». In the worksheet shown, column D is is used to record the date a task was completed. Therefore, if the column contains a date (i.e. is not blank), we can assume the task is complete. This problem can be solved with the IF function alone or with the IF function and the ISBLANK function. It can also be solved with the LEN function. All three approaches are explained below.

IF function

The IF function runs a logical test and returns one value for a TRUE result, and another value for a FALSE result. You can use IF to test for a blank cell like this:

=IF(A1="",TRUE) // IF A1 is blank
=IF(A1<>"",TRUE) // IF A1 is not blank

In the first example, we test if A1 is empty with =»». In the second example, the <> symbol is a logical operator that means «not equal to», so the expression A1<>»» means A1 is «not empty». In the worksheet shown, we use the second idea in cell E5 like this:

=IF(D5<>"","Done","")

If D5 is «not empty», the result is «Done». If D5 is empty, IF returns an empty string («») which displays as nothing. As the formula is copied down, it returns «Done» only when a cell in column D contains a value. To display both «Done» and «Not done», you can adjust the formula like this:

=IF(D5<>"","Done","Not done")

ISBLANK function

Another way to solve this problem is with the ISBLANK function. The ISBLANK function returns TRUE when a cell is empty and FALSE if not. To use ISBLANK directly, you can rewrite the formula like this:

=IF(ISBLANK(D5),"","Done")

Notice the TRUE and FALSE results have been swapped. The logic now is if cell D5 is blank. To maintain the original logic, you can nest ISBLANK inside the NOT function like this:

=IF(NOT(ISBLANK(D5)),"Done","")

The NOT function simply reverses the result returned by ISBLANK.

LEN function

One problem with testing for blank cells in Excel is that ISBLANK(A1) or A1=»» will both return FALSE if A1 contains a formula that returns an empty string. In other words, if a formula returns an empty string in a cell, Excel interprets the cell as «not empty». To work around this problem, you can use the LEN function to test for characters in a cell like this:

=IF(LEN(A1)>0,TRUE)

This is a much more literal formula. We are not asking Excel if A1 is blank, we are literally counting the characters in A1. The LEN function will return a positive number only when a cell contains actual characters.

How to check if a cell is empty or is not empty in Excel; this tutorial shows you a couple different ways to do this.

Sections:

Check if a Cell is Empty or Not — Method 1

Check if a Cell is Empty or Not — Method 2

Notes

Check if a Cell is Empty or Not — Method 1

Use the ISBLANK() function.

This will return TRUE if the cell is empty or FALSE if the cell is not empty.

Here, cell A1 is being checked, which is empty.

When the cell is not empty, it looks like this:

FALSE is output because cell B1 is not empty.

Reverse the True/False Output

Some formulas need to have TRUE or FALSE reversed in order to work correctly; to do this, use the NOT() function.

Result:

Whereas ISBLANK() output a TRUE for cell A1, the NOT() function reversed that and changed it to FALSE.

The same works for changing FALSE to TRUE.

Check if a Cell is Empty or Not — Method 2

You can also use an IF statement to check if a cell is empty.


=IF(A1="","Empty","Not Empty")

Result:

The function checks if this part is true: A1=»» which checks if A1 is equal to nothing.

When there is something in the cell, it works like this:

Cell B1 is not empty so we get a Not Empty result.

In this example I set the IF statement to output «Empty» or «Not Empty» but you can change it to whatever you like.

Reverse the Check

The example above checked if the cell was empty, but you can also check if the cell is not empty.

There are a few different ways to do this, but I will show you a simple and easy method here.


=IF(A1<>"","Not Empty","Empty")

Notice the check this time is A1<>»» and that says «is cell A1 not equal to nothing.» It sounds confusing but just remember that <> is basically the reverse of =.

I also had to switch the «Empty» and «Not Empty» in order to get the correct result since we are now checking if the cell is not empty.

Result:

As you can see, it outputs the same result as the previous example, just like it should.

Using <> instead of = merely reverses it, making a TRUE become a FALSE and a FALSE become a TRUE, which is why «Empty» and «Not Empty» had to be reversed in order to still output the correct result.

Notes

It may seem useless to return TRUE or FALSE like in the first method, but remember that many functions in Excel, including IF(), AND(), and OR() all rely on results that are either TRUE or FALSE.

Checking for blanks and returning TRUE or FALSE is a simple concept but it can get a bit confusing in Excel, especially when you have complex formulas that rely on the result of the formulas in this tutorial.

Вы можете использовать следующую формулу в Excel для выполнения какой-либо задачи, если ячейка не пуста:

=IF( A1 <> "" , Value_If_Not_Empty, Value_If_Empty)

Эта конкретная формула проверяет, пуста ли ячейка A1 .

Если он не пустой, то возвращается Value_If_Not_Empty .

Если он пуст, возвращается значение Value_If_Empty .

В следующем примере показано, как использовать эту формулу на практике.

Пример: используйте формулу «Если не пусто» в Excel

Предположим, у нас есть следующий набор данных в Excel, который содержит информацию о различных баскетбольных командах:

Мы можем использовать следующую формулу, чтобы вернуть значение «Команда существует», если ячейка в столбце A не пуста.

В противном случае мы вернем значение «Не существует»:

=IF( A2 <> "" , "Team Exists", "Does Not Exist")

На следующем снимке экрана показано, как использовать эту формулу на практике:

Если имя команды не пусто в столбце А, возвращается «Команда существует».

В противном случае возвращается «Не существует».

Если бы мы хотели, мы могли бы также возвращать числовые значения вместо символьных значений.

Например, мы могли бы использовать следующую формулу, чтобы вернуть значение столбца очков, разделенное на два, если ячейка в столбце A не пуста.

В противном случае мы вернем пустое значение:

=IF( A2 <> "" , B2 / 2 , "" )

На следующем снимке экрана показано, как использовать эту формулу на практике:

Если название команды не пусто в столбце A, то мы возвращаем значение в столбце очков, умноженное на два.

В противном случае мы возвращаем пустое значение.

EXCEL FORMULA 1. If a cell is not blank using the IF function

EXCEL

Hard coded formula

Cell reference formula

GENERIC FORMULA

=IF(cell_ref<>»», value_if_true, value_if_false)

ARGUMENTS
cell_ref: A cell that you want to check if it’s not blank.
value_if_true: Return a value if the cell that is being tested is not blank.
value_if_false: Return a value if the cell that is being tested is blank.

GENERIC FORMULA

=IF(cell_ref<>»», value_if_true, value_if_false)

EXPLANATION

This formula uses the IF function with a test criteria of two double quotation marks («»), without any value inserted between them and ‘does not equal to’ sign (<>) in front of them, to assess if a cell is not empty and return a specific value. The expression <>»» means «not empty». If a cell is not blank the formula will return a value that has been assigned as the true value, alternatively if a cell is blank the formula will return a value assigned as the false value.

With this formula you can enter the values, that will be returned if the cell is empty or not, directly into the formula or reference them to specific cells that capture these values.

Click on either the Hard Coded or Cell Reference button to view the formula that has the return values directly entered into the formula or referenced to specific cells that capture these values, respectively.

In this example the formula tests if a specific cell is not blank. If the cell is not blank the formula will return a value of «Yes» (hard coded example) or value in cell C5 (cell reference example). If the cell is empty the formula will return a value of «No» (hard coded example) or value in cell C6 (cell reference example).

If you are using the formula with values entered directly in the formula and want to return a numerical value, instead of a text value, you do not need to apply the double quotation marks around the values that are to be returned e.g. (=IF(C5<>»»,1,0)).

EXCEL FORMULA 2. If a cell is not blank using the IF, NOT and ISBLANK functions

EXCEL

Hard coded formula

Cell reference formula

GENERIC FORMULA

=IF(NOT(ISBLANK(cell_ref)), value_if_true, value_if_false)

ARGUMENTS
cell_ref: A cell that you want to check if it’s blank.
value_if_true: Value to be returned if the cell that is being tested is blank.
value_if_false: Value to be returned if the cell that is being tested is not blank.

GENERIC FORMULA

=IF(NOT(ISBLANK(cell_ref)), value_if_true, value_if_false)

EXPLANATION

This formula uses a combination of the IF, NOT and ISBLANK functions to assess if a cell is not blank and return a specific value. Unlike the first formula, which uses the double quotation marks («») to test if the selected cell is not blank, this formula uses the NOT and ISBLANK functions. If the cell is not blank the ISBLANK function will return FALSE, alternatively it will return TRUE. The NOT function will then return the opposite to what the ISBLANK function has returned. Therefore, if the cell is not blank the combination of the NOT and ISBLANK function will return a TRUE value. The formula will then return a value that has been assigned as the true value, alternatively if the cell is blank the formula will return a value assigned as the false value.

With this formula you can enter the values, that will be returned if the cell is empty or not, directly into the formula or reference them to specific cells that capture these values.

Home / Excel Formulas / IF Cell is Blank (Empty) using IF + ISBLANK

In Excel, if you want to check if a cell is blank or not, you can use a combination formula of IF and ISBLANK. These two formulas work in a way where ISBLANK checks for the cell value and then IF returns a meaningful full message (specified by you) in return.

In the following example, you have a list of numbers where you have a few cells blank.

Formula to Check IF a Cell is Blank or Not (Empty)

First, in cell B1, enter IF in the cell.
Now, in the first argument, enter the ISBLANK and refer to cell A1 and enter the closing parentheses.
Next, in the second argument, use the “Blank” value.
After that, in the third argument, use “Non-Blank”.
In the end, close the function, hit enter, and drag the formula up to the last value that you have in the list.

As you can see, we have the value “Blank” for the cell where the cell is empty in column A.

=IF(ISBLANK(A1),"Blank","Non-Blank")

Now let’s understand this formula. In the first part where we have the ISBLANK which checks if the cells are blank or not.

And, after that, if the value returned by the ISBLANK is TRUE, IF will return “Blank”, and if the value returned by the ISBLANK is FALSE IF will return “Non_Blank”.

Alternate Formula

You can also use an alternate formula where you just need to use the IF function. Now in the function, you just need to specify the cell where you want to test the condition and then use an equal operator with the blank value to create a condition to test.

And you just need to specify two values that you want to get the condition TRUE or FALSE.

You can use the following formula in Excel to perform some task if a cell is not empty:

=IF(A1<>"", Value_If_Not_Empty, Value_If_Empty)

This particular formula checks if cell A1 is empty.

If it is not empty, then Value_If_Not_Empty is returned.

If it is empty, then Value_If_Empty is returned.

The following example shows how to use this formula in practice.

Example: Use “If Not Empty” Formula in Excel

Suppose we have the following dataset in Excel that contains information about various basketball teams:

We can use the following formula to return a value of “Team Exists” if the cell in column A is not empty.

Otherwise, we’ll return a value of “Does Not Exist”:

=IF(A2<>"", "Team Exists", "Does Not Exist")

The following screenshot shows how to use this formula in practice:

If the team name is not empty in column A, then “Team Exists” is returned.

Otherwise, “Does Not Exist” is returned.

If we’d like, we could also return numeric values instead of character values.

For example, we could use the following formula to return the value of the points column divided by two if the cell in column A is not empty.

Otherwise, we’ll return an empty value:

=IF(A2<>"", B2/2, "")

The following screenshot shows how to use this formula in practice:

If the team name is not empty in column A, then we return the value in the points column multiplied by two.

Otherwise, we return an empty value.

We can determine if a cell is not blank in Excel by either using the IF function or by using the IF and ISBLANK function combined. This tutorial will assist all levels of Excel users in both methods to identify non-blank cells

Figure 1. Final result: Determine if a cell is not blank in Excel

IF Function in Excel

IF function evaluates a given logical test and returns a TRUE or a FALSE

Syntax

=IF(logical_test, [value_if_true], [value_if_false])

The arguments “value_if_true” and “value_if_false” are optional. If left blank, the function will return TRUE if the logical test is met, and FALSE if otherwise.

ISBLANK Function in Excel

ISBLANK function is more straightforward. It tests whether a value or a cell is blank or not.

Syntax

=ISBLANK(value)

The function returns TRUE if the value is blank; FALSE if otherwise

Setting up the Data

Below is a list of Projects and a column for Date Completed. We want to know if column C for the “Date Completed” is blank or not.

Figure 2. Sample data to determine if a cell is not blank

Determine If a Cell is Not Blank

Using the IF function

In cell D3, enter the formula:

=IF(C3<>"","Not blank","Blank")

The symbol <> in Excel means “not equal to”
“” in Excel means empty string, or blank
C3<>”” means C3 is not equal to blank, or C3 is not blank

This formula returns “Not blank” because cell C3 is not blank. It has the value “July 26, 2018”.

Figure 3. Entering the IF formula to determine if a cell is not blank

In cell D4, enter the formula:

=IF(C4<>"","Not blank","Blank")

The result is “Blank” because cell D4 is empty.

Figure 4. Output: Using IF to determine if a cell is not blank

Using the IF and ISBLANK function

In cell D5, enter the formula:

=IF(ISBLANK(C5),"Blank","Not Blank")

ISBLANK evaluates whether cell C5 is blank or not
If the ISBLANK function returns TRUE, the formula will return “Blank”; otherwise, it returns “Not Blank”
The result is “Blank” because C5 is empty

Figure 5. Final result: Using IF and ISBLANK to determine if a cell is not blank

Note

We can customize the action that the IF function will return depending on the logical test results.

Example

We want to return the status “Completed” if the cell in column C is not blank, and “In Progress” if otherwise.

Enter the following formula:

In cell D3: =IF(C3<>"","Completed","In Progress")

In cell D4: =IF(C4<>"","Completed","In Progress")

In cell D5: =IF(ISBLANK(C5),"In Progress","Completed")

In cell D6: =IF(ISBLANK(C6),"In Progress","Completed")

In row 4, I want the difference of months of years 2109 and 2018. For that, I will subtract 2018’s month’s data from 2019’s month’s data. The condition is, if either cell is blank, there should be no calculation. Let’s explore in how many ways you can force excel, if cell is not blank.

Calculate If Not Blank using IF function with OR Function.
The first function we think of is IF function, when it comes to conditional output. In this example, we will use IF and OR function together.
So if you want to calculate if all cells are non blank then use below formula.
Write this formula in cell B4 and fill right (CTRL+R).

=IF(OR(B3=»»,B2=»»),»»,B2-B3)

How Does It work?
The OR function checks if B3 and B2 are blank or not. If either of the cell is blank, it returns TRUE. Now, for True, IF is printing “” (nothing/blank) and for False, it is printing the calculation.

The same thing can be done using IF with AND function, we just need to switch places of True Output and False Output.

=IF(AND(B3<>»»,B2<>»»),B2-B3,»»)

In this case, if any of the cells is blank, AND function returns false. And then you know how IF treats the false output.

Using the ISBLANK function
In the above formula, we are using cell=”” to check if the cell is blank or not. Well, the same thing can be done using the ISBLANK function.

=IF(OR(ISBLANK(B3),ISBLANK(B2)),””,B2-B3)

It does the same “if not blank then calculate” thing as above. It’s just uses a formula to check if cell is blank or not.

Calculate If Cell is Not Blank Using COUNTBLANK
In above example, we had only two cells to check. But what if we want a long-range to sum, and if the range has any blank cell, it should not perform calculation. In this case we can use COUNTBLANK function.

=IF(COUNTBLANK(B2:H2),»»,SUM(B2:H2))

Here, count blank returns the count blank cells in range(B2:H2). In excel, any value grater then 0 is treated as TRUE. So, if ISBLANK function finds a any blank cell, it returns a positive value. IF gets its check value as TRUE. According to the above formula, if prints nothing, if there is at least one blank cell in the range. Otherwise, the SUM function is executed.

Using the COUNTA function
If you know, how many nonblank cells there should be to perform an operation, then COUNTA function can also be used.
For example, in range B2:H2, I want to do SUM if none of the cells are blank.
So there is 7 cell in B2:H2. To do calculation only if no cells are blank, I will write below formula.

=IF(COUNTA(B3:H3)=7,SUM(B3:H3),»»)

As we know, COUNTA function returns a number of nonblank cells in the given range. Here we check the non-blank cell are 7. If they are no blank cells, the calculation takes place otherwise not.

This function works with all kinds of values. But if you want to do operation only if the cells have numeric values only, then use COUNT Function instead.

So, as you can see that there are many ways to achieve this. There’s never only one path. Choose the path that fits for you. If you have any queries regarding this article, feel free to ask in the comments section below.
