Isempty vba excel что это

В этом учебном материале вы узнаете, как использовать Excel функцию ISEMPTY с синтаксисом и примерами.

Описание

Функцию ISEMPTY Microsoft Excel можно использовать для проверки пустых ячеек или неинициализированных переменных.
Функция ISEMPTY — это встроенная в Excel функция, которая относится к категории информационных функций. Её можно использовать как функцию VBA в Excel.
В качестве функции VBA вы можете использовать эту функцию в коде макроса, который вводится через редактор Microsoft Visual Basic Editor.

Синтаксис

Синтаксис функции ISEMPTY в Microsoft Excel:

IsEmpty( value )

Аргументы или параметры

value

Значение, которое вы хотите проверить.
Если value — пустая ячейка или неинициализированная переменная, эта функция вернет True. В противном случае функция вернет False.

Возвращаемое значение

Функция ISEMPTY возвращает True, если value является пустой ячейкой или неинициализированной переменной.
Функция ISEMPTY возвращает False, если value является ячейкой или переменной, содержащей значение (т.е. не пусто).

Примечание

• См. также функцию ЕПУСТО (функция рабочего листа).

Применение

• Excel для Office 365, Excel 2019, Excel 2016, Excel 2013, Excel 2011 для Mac, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000

Тип функции

• Функция VBA

Пример (как функция VBA)

Функцию ISEMPTY можно использовать только в коде VBA в Microsoft Excel. Мы можем использовать функцию ISEMPTY для проверки ячейки рабочего листа или переменной.
Давайте рассмотрим оба этих случая.

С ячейкой рабочего листа

Если вы хотите проверить, пуста ли ячейка рабочего листа в VBA, вы не можете использовать функцию рабочего листа ЕПУСТО. В VBA необходимо использовать функцию ISEMPTY. Вот пример того, как с помощью функции ISEMPTY проверить, пуста ли ячейка листа:

В этом примере мы проверим, пуста ли ячейка A1.
Если ячейка A1 пуста, отобразится сообщение «Ячейка A1 пуста».

С переменной

Функцию ISEMPTY также можно использовать для проверки, инициализирована ли переменная.
Если переменная не была инициализирована, функция ISEMPTY вернет true. В противном случае функция вернет false.

Переменная не инициализирована

Давайте сначала рассмотрим пример, когда переменная не была инициализирована:

В этом примере переменная с именем LResult была объявлена, но не была инициализирована значением. В результате функция ISEMPTY вернет true и отобразит сообщение «Переменная не инициализирована.»

Переменная инициализирована

Теперь мы изменим приведенный выше пример и инициализируем переменную LResult перед вызовом функции ISEMPTY.

Поскольку переменная LResult теперь инициализирована значением «Google is simply the best search engine!», Функция ISEMPTY вернет false, и окно сообщения отображаться не будет.

VBA IsEmpty

IsEmpty is a function which is used to check whether the cell being referred to is empty or not. It is very similar to the ISBLANK function in excel. The IsEmpty function in Excel VBA is also called an information function in excel as it gives the information on whether the given cell is blank or not.

IsEmpty function is an inbuilt function in Excel VBA. As explained in the above definition it is used to determine whether the given cell is blank or not. If the given cell is empty we can display a message to the user that the cell is empty and if it is not empty we can display the message that the cell is not empty.

Syntax of IsEmpty in Excel VBA

The syntax for Isempty function is as follows:

We can use this function to check whether a single cell is empty or the whole range of data is empty or not. There are two values returned by this function. One is true while another one is false. If the given cell is blank the function returns the value as true and if the given cell is not blank it gives value as false.

How to Use VBA IsEmpty Function in Excel?

We will learn how to use a VBA IsEmpty function with few examples in excel.

You can download this VBA IsEmpty Excel Template here – VBA IsEmpty Excel Template

VBA IsEmpty – Example #1

First, let us see the value returned by this function how it works.

Follow the below steps to use VBA IsEmpty function in Excel:

Step 1: Go to the developer’s tab and click on visual basic.

Step 2: Write the following code in the project.

Code:

Sub Check1()

Dim MyCheck As String
MyCheck = IsEmpty(Range("A1").Value)
MsgBox MyCheck

End Sub

First, let us understand the code written above step by step:

• Check is the name of the subfunction defined.
• Mycheck is the variable we have defined it as a string because the Isempty function returns a logical value.
• Mycheck stores the value of Isempty returned when it checks the cell A1.
• The value stored in Mycheck Variable is displayed by MsgBox function.

Step 3: Run the code by clicking the run button.

We can see that value returned by the function is true as cell A1 is empty.

VBA IsEmpty – Example #2

Now let us use Isempty function with if function to check for a certain cell in a worksheet whether it is blank or not.

Follow the below steps to use VBA IsEmpty function in Excel:

Step 1: In the developer’s tab click on Visual Basic under the code’s section.

Step 2: Write the following code in the code window,

Code:

Sub Sample1()
If IsEmpty(Range("A1")) = False Then

    MsgBox "Cell A1 is not empty"
Else

    MsgBox "Cell A1 is empty"
End If
End Sub

Let us again understand the code written above once again.

• First, we have defined our subfunction as Sample1.
• We nest Isempty function with If function to check whether cell A1 is empty or not.
• If cell A1 is empty we use msgbox function to display the message that the given cell is empty.
• If the cell A1 is not empty we use msgbox function to display the message that the given cell is not empty.

Step 3: Run the above code by clicking on the run button.

We see the result displayed as cell A1 is empty.

Step 4: Now put a random value in cell A, for example, I have put a value A in cell A1.

Step 5: Now run the code again and we get the following result.

VBA IsEmpty – Example #3

Now let’s use this function to find out whether the given range of cells is blank or not. Earlier we used this function in a single cell. In this example, our data range will be from B1:D7.

Follow the below steps to use VBA IsEmpty function in Excel:

Step 1: In the developer’s tab click on Visual Basic under the code’s section.

Step 2: Write the following code in the code window,

Code:

Sub Sample2()
Dim cell As Range
Dim bIsEmpty As Boolean

bIsEmpty = False
For Each cell In Range("B1:D7")
    If IsEmpty(cell) = True Then
        bIsEmpty = True
        Exit For
    End If
Next cell

If bIsEmpty = True Then

    MsgBox "empty cells"
Else

    MsgBox "cells have values!"
End If
End Sub

Let us understand the above-written code step by step.

• After defining the subfunction as Sample 2 we have defined a variable named cell as Range and B is empty as Boolean as Boolean stores logical values.
• We have predefined that Bisempty will be false if the cell range given is not empty.
• But if the given cell range is empty the Value stored in Bisempty will be true.
• If the value stored in Bisempty variable is true we display a message as Empty cells or if the value stored in the variable is false we display the message as Cells have values.

Step 3: Run the above code by clicking on the run button.

We see the following result displayed as cell A1 is empty.

Things to Remember

There are few things which we need to remember about Isempty Function in Excel VBA:

• Isempty is similar to Isblank function in Excel.
• IsEmpty is an information function.
• IsEmpty function returns a logical value i.e. true or false.
• IsEmpty function can be used of a single cell or for a range of cells.

IsEmpty is a worksheet function used to find out whether a given cell reference or a range of cells is empty or not. Since it is a worksheet function, we use the Application to use it in VBA. It is the worksheet method in VBA to use this function. This function comes under the logical lists of functions and returns “True” if the reference is empty.

VBA IsEmpty Function

VBA IsEmpty is a logical function that tests whether the selected is empty or not. Since it is a logical function, it will return the results in Boolean values, i.e., TRUE or FALSE.

If the selected cell is empty, it will return TRUE, or else it will return FALSE.

What Does ISEMPTY Function Do in VBA?

Often empty cells frustrate us from working efficiently on the worksheet. Finding the blank cells is not the hardest, but if empty cells hide them in the middle of the data, it takes a toll to find them.

To find the empty cells in Excel, we have the ” ISBLANK ” function as a worksheet function, but in VBA, it is called “ISEMPTY.”

It works similarly to the worksheet function “ISBLANK”. Now, look at the below formula of the “ISEMPTY” function.

As we can see in the above image, it returns the result as Boolean, i.e., TRUE or FALSE.

Examples of ISEMPTY Function in VBA

The following are examples of IsEmpty in VBA.

You can download this VBA IsEmpty Excel Template here – VBA IsEmpty Excel Template

Example #1

Now, we will see the first practical example of “ISEMPTY.” For this, take a look at the below image of the worksheet.

Now, we will apply Excel VBA ISEMPTY function to test all these.

Step 1: Define the variable as Boolean.

Code:

Sub IsEmpty_Example1()

  Dim K As Boolean

End Sub

Step 2: Assign the value through VBA ISEMPTY function for this variable.

Code:

Sub IsEmpty_Example1()
  Dim K As Boolean

  K = IsEmpty(

End Sub

Step 3: Expression is nothing but what is the cell we are testing. Now, we are testing the A1 cell.

Code:

Sub IsEmpty_Example1()
  Dim K As Boolean

  K = IsEmpty(Range("A1").Value)

End Sub

Step 4: Show the value of this variable in the VBA Msgbox.

Code:

Sub IsEmpty_Example1()
  Dim K As Boolean

  K = IsEmpty(Range("A1").Value)
  MsgBox K

End Sub

Run this code to check the result.

Since there is a value in cell A1, we got the result as FALSE.

Now, we will change the cell reference from A1 to A5.

Code:

Sub IsEmpty_Example1()
  Dim K As Boolean

  K = IsEmpty(Range("A5").Value)
  MsgBox K

End Sub

Run this code to see the result.

We got the result as TRUE. The referenced cell A5 is an empty cell, so we got the result as “TRUE.”

Now, we will test cell A8.

Code:

Sub IsEmpty_Example1()
  Dim K As Boolean

  K = IsEmpty(Range("A8").Value)
  MsgBox K

End Sub

Run this code to see the result.

We got the result as FALSE even though there is no value in cell A8.

Now, is it an error result from the ISEMPTY formula?

No… Absolutely No!

When examining cell A8, there was a space character inside the cell that is not easy to see with bare eyes.

So, the conclusion is even space is considered a character in Excel and VBA language.

Example #2 – Combination of VBA ISEMPTY with IF Condition

The real usage of the function “ISEMPTY” is admirable when we use it with other logical functions.

Especially when we use it with IF conditions, we can derive many useful results from it.

For this demonstration, take a look at the below example.

In the “Status” column, if the “PF Status” column is empty, we need the value “No Update.” If there is any value, we need the values as “Collected Updates.”

Remember here that we do not need the default result of TRUE or FALSE. We need our results here. We need to use Excel VBA ISEMPTY with IF conditions to have our results.

Step 1: Open IF condition.

Code:

Sub IsEmpty_Example2()

  If

End Sub

Step 2: Inside the IF condition, open the ISEMPTY function.

Code:

Sub IsEmpty_Example2()

  If IsEmpty(

End Sub

Step 3: The first logical test is cell B2 value is empty or not.

Code:

Sub IsEmpty_Example2()

  If IsEmpty(Range("B2").Value) Then

End Sub

Step 4: If the logical test in excelA logical test in Excel results in an analytical output, either true or false. The equals to operator, “=,” is the most commonly used logical test.read more VBA is TRUE, i.e., if the cell is empty, we need the resultas “No Update” in cell C2.

Code:

Sub IsEmpty_Example2()

  If IsEmpty(Range("B2").Value) Then
    Range("C2").Value = "No Update"

End Sub

Step 5: If the logical test is FALSE, we need the result in cell C2 as “Collected Updates.”

Code:

Sub IsEmpty_Example2()

  If IsEmpty(Range("B2").Value) Then
    Range("C2").Value = "No Update"
  Else
    Range("C2").Value = "Collects Updates"
  End If

End Sub

We have completed it now.

Run the code to get the result.

We got the “Collected Updates” result because we have the non-empty cell in B2.

Now, similarly, apply the code for other cells to test.

Code:

Sub IsEmpty_Example2()

  If IsEmpty(Range("B2").Value) Then
    Range("C2").Value = "No Update"
  Else
    Range("C2").Value = "Collects Updates"
  End If

  If IsEmpty(Range("B3").Value) Then
    Range("C3").Value = "No Update"
  Else
    Range("C3").Value = "Collected Updates"
  End If
 
  If IsEmpty(Range("B4").Value) Then
    Range("C4").Value = "No Update"
  Else
    Range("C4").Value = "Collected Updates"
  End If

End Sub

Run this code to have the results.

In cell C3, we got the result as “No Update” because there is no value in cell B3, i.e., an empty cell. Since the logical formula returned TRUE, we got the individual result.

Example #3 – Alternative to VBA ISEMPTY Function

We have an alternative to the ISEMPTY function; without applying the Excel VBA ISEMPTY function, we can test the cell.

For an example, look at the below code.

Code:

Sub IsEmpty_Example3()

  If Range("B2").Value = "" Then
    Range("C2").Value = "No Update"
  Else
    Range("C2").Value = "Collected Updates"
  End If

End Sub

The line of code Range(“B2″).Value = ” ” means whether the cell B2 cell is equal to empty or not.

Double Quotes (“”) represent an empty cell or not if the empty result is TRUE or else FALSE.

This article has been a guide to VBA ISEMPTY function. Here, we learned how to use the VBA ISEMPTY function in Excel, the Combination of IsEmpty with the IF condition, some practical examples, and a downloadable Excel template. Below are some useful Excel articles related to VBA: –

• Boolean in VBA
• False Function in Excel
• OFFSET in VBA
• Date Function in VBA

In this article, you will learn how to use the IsEmpty function in VBA to check if a cell is empty. If you want to do the same in Excel, a similar function is the IsBlank function. In this step-by-step tutorial, for all levels of Excel and VBA users, you will see how to use both functions.

Using the IsEmpty function in VBA

As we already mentioned in the introduction, the IsEmpty is the simple function in VBA which checks if a cell is empty. If the selected does not contain any value, the function will return Boolean TRUE. On the other side, if the cell contains a value, the function returns FALSE. Here is the code:

If IsEmpty(Sheet1.Range("A1").Value) = True Then

    Sheet1.Range("B1").Value = "The cell A1 is empty"

Else

    Sheet1.Range("B1").Value = "The value in A1 is " & Sheet1.Range("A1").Value

End If

In the example, we want to check if the cell A1 in the Sheet1 contains any value. Therefore, if the cell is empty, we will return “The cell A1 is empty” in the cell B1. If the cell contains a value, we will return the value of the cell A1 in the cell B1. Let’s run the code first with empty A1 and then with A1 containing some value:

Image 2. Using the IsEmpty in VBA with populated cell

Using the IsBlank function in Excel

The IsBlank function also checks if the value of the cell is blank, but this function does not exist in VBA. We’ll see on similar examples how to check if the cell is blank in Excel, using this formula:

=ISBLANK(A1)

Image 3. Using the IsBlank in Excel with blank A1 cell

Image 4. Using the IsBlank in Excel with populated A1 cell

As you can see, we check if the cell A1 is blank and return the result of the function in the cell B1. In Image 3, the result of the function is Boolean TRUE. On the other side, in Image 4, the result of the function is FALSE, as the cell A1 is “11” and is not blank.
