Excel VBA Concatenation Operators

  • Last Updated : 19 Jul, 2021

VBA in Excel stands for Visual Basic for Applications which is Microsoft’s programming language. To optimize the performance and reduce the time in Excel we need Macros and VBA is the tool used in the backend. Concatenation means to join two or more data into a single data. There are various ways we can perform concatenation in Excel using built-in functions, operators, etc.

Some helpful links to get more insights about concatenate and using VBA in Excel :

  2. CONCATENATE in Excel
  3. How to Create a Macro in Excel?

In this article, we are going to see about concatenate operators and how to use VBA to concatenate strings as well as numbers.

Implementation :

In the Microsoft Excel tabs, select the Developer Tab. Initially, the Developer Tab may not be available. 



The Developer Tab can be enabled easily by a two-step process :

  • Right-click on any of the existing tabs at the top of the Excel window.
  • Now select Customize the Ribbon from the pop-down menu.

  • In the Excel Options Box, check the box Developer to enable it and click on OK.

  • Now, the Developer Tab is visible.

Now, we need to open the Visual Basic Editor. There are two ways :

  • Go to Developer and directly click on the Visual Basic tab.
  • Go to the Insert tab and then click on the Command button. Drag and insert the command button in any cell of the Excel sheet.

Now, double-click on this command button. This will open the Visual Basic Application Editor tab, and we can write the code. The benefit of this command button is that just by clicking on the button we can see the result of concatenation, and also we don’t need to make any extra Macro in Excel to write the code.



Another way is by right-clicking on the command button and then select View Code as shown below :

CONCATENATE Operators:

To concatenate operator mostly used in Excel is “&” for numbers as well as strings. But for strings, we can also use “+” operator to concatenate two or more strings.

The syntax to concatenate using formula is :

cell_number1 & cell_number2 ; without space in between

cell_number1 & " " & cell_number2;  with space in between

cell_number1 & "Any_Symbol" & cell_number2 ; with any symbol in between

cell_number(s) & "string text" ; concatenate cell values and strings

"string_text" & cell_number(s) ; concatenate cell values and strings

CONCATENATE  Two Numbers:

Example 1: Take any two numbers as input and concatenate into a single number.

The code to concatenate two numbers in Excel is :

Private Sub CommandButton1_Click()
'Inserting the number num1 and num2 
Dim num1 As Integer: num1 = 10
Dim num2 As Integer: num2 = 50
'Declare a variable c to concatenate num1 and num2
Dim c As Integer
'Concatenate the numbers
c = num1 & num2
MsgBox ("The result after concatenating two numbers are: " & c)
End Sub

Run the above code in VBA and the output will be shown in the message box.

Output :

The result after concatenating two numbers are: 1050



You can also click on the command button and the same message will be displayed. 

Example 2: Say, now we take two numbers from the cells of the Excel Sheet and store the result back in the Excel sheet. This time we are not going to use the command button.

Step 1: Open the VB editor from the Developer Tab.

Developer  -> Visual Basic -> Tools -> Macros

Step 2: The editor is now ready where we can write the code and syntax for concatenation.

Now write the following code and run it.

Sub Concatenate_Numbers()
'Taking two variables to fetch the two numbers and to store
Dim num1 As Integer
Dim num2 As Integer
'Fetching the numbers from Excel cells num1 from A2 and num2 from B2
num1 = Range("A2").Value
num2 = Range("B2").Value
'Find the concatenate and store in cell number C2
Range("C2").Value = num1 & num2
End Sub

CONCATENATED

Concatenate Two Or more strings:

We can use either “+” operator or “&” operator.

Example 1: Let’s concatenate the strings “Geeks”, “for”, “Geeks”.



Repeat Step 1 as discussed in the previous section to create a new VBA module of name “Concatenate_Strings”

Now write either of the following codes and run it to concatenate two or more strings.

Sub Concatenate_Strings()
'Taking three variables to fetch three strings and to store
Dim str1 As String
Dim str2 As String
Dim str3 As String
'Fetching the strings from Excel cells
str1 = Range("A2").Value
str2 = Range("B2").Value
str3 = Range("C2").Value
'Find the concatenate and store in cell number D2
Range("D2").Value = str1 + str2 + str3
End Sub
Sub Concatenate_Strings()
'Taking three variables to fetch three strings and to store
Dim str1 As String
Dim str2 As String
Dim str3 As String
'Fetching the strings from Excel cells
str1 = Range("A2").Value
str2 = Range("B2").Value
str3 = Range("C2").Value
'Find the concatenate and store in cell number D2
Range("D2").Value = str1 & str2 & str3
End Sub

CONCATENATED

Example 2: Let’s concatenate three strings and add in different lines and display them in a message box this time.

Create a new module and write the code. The keyword used for adding the string in the next line is vbNewLine

The code is :

Sub Concatenate_DifferentLines()
'Taking three variables to store
Dim str1 As String
Dim str2 As String
Dim str3 As String
'Initialize the strings
str1 = "The best platform to learn any programming is"
str2 = "none other than GeeksforGeeks"
str3 = "Join today for best contents"
'Display the concatenated result in a message box
MsgBox (str1 & vbNewLine & str2 & vbNewLine & str3)
End Sub

Example 3: Let’s concatenate two strings with space in between by taking an example of the full name of a person which contains First Name and Last Name.

Create a new module Concatenate_Strings_Space and write the following code :

Sub Concatenate_Strings_Space()
'Taking two variables to fetch two strings and to store
Dim fname As String
Dim lname As String
'Fetching the strings from Excel cells
fname = Range("A2").Value
lname = Range("B2").Value
'Find the concatenate and store in cell number C2
Range("C2").Value = fname & " " & lname
End Sub
