The VBA IsEmpty() function is used to check whether a variable or a field in an Excel spreadsheet is empty or not. It returns a Boolean value True if the variable or field is empty, and False if it is not empty.

VBA IsEmpty Function – Purpose, Syntax and Arguments


The IsEmpty() function is useful for validating user inputs or checking the status of optional variables in a VBA program. It can prevent errors caused by trying to access or manipulate empty variables, and allow for more efficient and accurate data handling.




  • Varname: This is the name of the variable or cell in a spreadsheet that you want to check.


In the following VBA code, we define a variable myString and use the IsEmpty() function to check its status:

Sub CheckEmpty()
    Dim myString As String 'declare variable
    myString = "" 'assign empty value
    If IsEmpty(myString) = True Then 'check if variable is empty
        MsgBox("Variable is empty") 'display message
    End If
End Sub

The message box will be displayed as the variable myString has an empty value.


  • The IsEmpty() function can only be used with variables or fields with variant data type. It cannot be used with other data types such as numbers or dates.
  • If the variable passed to the function is not declared, an error will occur.
  • The IsEmpty() function also considers a variable or field containing a single space character as empty.

Important Notes:

  • The IsEmpty() function does not differentiate between a variable with an empty string value and a variable that has not been assigned any value. Both will return True.
  • The IsNull() function can be used to specifically check for Null values, which are different from empty values.
  • The IsEmpty() function can only be used in VBA code and cannot be used in Excel formulas.

Understanding VBA IsEmpty Function with Examples

Example 1: Using IsEmpty Function to Check if a Variable is Empty

Let’s start with a simple example where we will declare a variable and assign it a value. Then we will use the IsEmpty function to check if the variable has any value or is empty.

Dim myVar as String
myVar = "Hello"
Debug.Print IsEmpty(myVar)

The Debug.Print command is used to display the result in the Immediate window in the VBA editor. When we run this code, the Immediate window will show the result as False. This means that the variable myVar has a value and is not empty.
We can also assign an empty value to the variable and check the result again.

myVar =""
Debug.Print IsEmpty(myVar)

This time, the result will be True, indicating that the variable is now empty. This example shows how the IsEmpty function can be used to check the value of a variable and take further action based on the result.

Example 2: Using IsEmpty Function to Check if a Cell is Empty

The IsEmpty function can also be used to check if a cell in an Excel sheet is empty or not. To do this, we need to specify the range of cells we want to check within the expression. Let’s say we have a data in cells A1 to A5, and we want to check if any of these cells are empty.

Debug.Print IsEmpty(Range("A1:A5"))

The result will be True if all the cells in the specified range are empty. However, if any of the cells have a value, the result will be False. This is useful when we want to check if a column or row in a worksheet contains any empty cells.

Example 3: Using IsEmpty Function to Check if a Range of Cells is Empty

We can also use the IsEmpty function to check if a range of cells is empty or not. In this example, we will use a For Loop to iterate through the cells in the range and check each cell for empty value.

Dim myRange as Range
Set myRange = Range("A1:A5")
For Each cell in myRange
    If IsEmpty(cell) = True Then
        Debug.Print "Cell " & cell.Address & " is empty."
        Debug.Print "Cell " & cell.Address & " is not empty."
    End If
Next cell

In this code, we have declared a range object called “myRange” and set it to A1:A5. Then, we use a For Loop to go through each cell in this range and use the IsEmpty function to check if it is empty or not. The result will be displayed in the Immediate window, showing which cells are empty and which are not.

Example 4: Using IsEmpty Function to Determine if a Userform Control is Empty

A userform is a custom dialog box that can be created in VBA to enhance the user experience of an Excel application. The IsEmpty function can also be used to check if the controls on a userform are empty or not. Let’s say we have a textbox control on our userform and we want to check if the user has entered any value in it before proceeding with our code.

If IsEmpty(UserForm1.TextBox1.Value) Then
    MsgBox "Textbox is empty."
    MsgBox "Textbox is not empty."
End If

In this example, we have named our userform as “UserForm1” and the textbox control as “TextBox1”. The IsEmpty function will check the value entered in the textbox and display a message accordingly.

Example 5: Using IsEmpty Function with Error Handling

In some cases, the IsEmpty function may give an error if the expression is invalid or if the expression itself gives an error. To handle these situations, we can use the On Error statement before using the IsEmpty function.

On Error Resume Next
Debug.Print IsEmpty("Text")

In this code, the On Error statement will ignore any errors that occur during the execution of the IsEmpty function. Instead of showing an error message, it will move to the next line of code. This example shows how we can use IsEmpty function with error handling to prevent the code from stopping abruptly.


The IsEmpty function in VBA is a useful tool for checking if a variable, cell, or range is empty or not. It can be used in various scenarios to ensure the proper functioning of our code. In this blog post, we have seen several examples of how the IsEmpty function can be used in different contexts. Experiment with the function in your own code and see how it can help improve the efficiency of your VBA projects.
