Excel vba str to int

Return to VBA Code Examples

You may be required to convert numbers stored as text to actual numbers in your VBA code. In this tutorial, we are going to go over the functions that you need to use to convert a string to an integer, long, double, decimal or currency data type (Click here to learn about converting numbers to strings)

Convert String to Integer

You can use the CInt or CLng function to convert a string to an integer. If the fraction is less than .5 the function will round down, if the fraction is greater than or equal to .5 the function will round up. The following code will convert a string to an integer:

MsgBox CInt("7.55")

The result is:
Using the CInt Function in VBA

The following code uses the CLng function to convert a string to an integer:

MsgBox CLng("13.5")

The result is:

Using the CLng Function in VBA

Note: You can use the CInt or CLng function to convert a string to an integer or long (respectively) data types. The Long Data type is the same as an integer data type except larger numbers are allowed. In the past, the distinction was required because of memory constraints. In modern programming, there’s no reason not to use the long data type since memory is no longer an issue. So it’s always better to use a long data type instead of an integer.

You can use the Immediate Window to see how the value would be processed if not converted to an integer:

Debug.Print "13.5" + "13.5"

Using the Immediate Window
Usually, the text will be stored as a variable and this variable will need to be converted to a number data type as shown in the code below:

Sub Using_Variables()

Dim valueOne As String
valueOne = 5
MsgBox CLng(valueOne) + CLng(valueOne)

End Sub

Convert String to Decimal

You can use the CDbl or CDec function to convert a string to a decimal. The following code would convert a string to a double data type:

MsgBox CDbl("9.1819")

The result is:

Converting a String to a Double Decimal Type

The following code would convert a string to a decimal data type:

MsgBox CDec("13.57") + CDec("13.4")

The result is:

Converting a string to a decimal data type in VBA

You can use the Immediate Window to see how the value would be processed if not converted to a double or decimal data type:

Debug.Print "13.57" + "13.4"

The result is:

Using Debug.Print to Display values

Note: The decimal data type can store larger numbers than the double data type, so it’s always advisable to use the decimal data type when you are uncertain.

Convert String to Currency

You can use the CCur function to convert a string to a currency. The following code would convert a string to a currency data type:

Range("A1").Value = CCur("18.5")

The result is:

Converting a String to the Currency Data Type

Syntax of CINT Function

The CINT is a data type conversion function. This function converts provided expressions into an Integer data type. When we say “Expression,” it must be a numerical value in the range of Integer data type in VBAIn VBA, an integer is a data type that may be assigned to any variable and used to hold integer values. In VBA, the bracket for the maximum number of integer variables that can be kept is similar to that in other languages. Using the DIM statement, any variable can be defined as an integer variable.read more, i.e., between -32768 to 32767.

Now, look at the syntax of the CINT function in VBA.

CINT Function

  • Expression is the value or the variable which contains the value that needs to convert to an Integer data type.

Note 1: When you pass, the expression value must be between -32768 to 32767. Otherwise, it will lead to an “Overflow” error, i.e., assigning the value over the data type’s limit.

Note 2: Expression must be a numerical value. If the expression is string value or text value, it will cause a “Run Time Error 13: Type Mismatch.”

This article will show you the Integer data type conversion from a string to an integer using the function “CINT.”

Example #1

Let us perform the first example of converting one fraction number to an Integer data type.

Code:

Sub CINT_Example1()

Dim IntegerNumber As String
Dim IntegerResult As Integer

IntegerNumber = 2564.589
IntegerResult = CInt(IntegerNumber)
MsgBox IntegerResult

End Sub
  • In the above code for the variable “IntegerNumber,” we have assigned the value as “2564.589.”
  • In the next line, we have applied a CINT function. So, it will convert the provided value to the nearest integer number.

VBA String to Integer Example 1

So, we got the result – 2565, and the supplied number is 2564.589. When the decimal value is more than 0.5, the CINT functions round up the number to the next Integer number. When the decimal value is less than or equal to 0.5, CINT functions round down to the same Integer number.

For an example, look at the below code where the number is less than 0.5.

Code:

Sub CINT_Example1()

Dim IntegerNumber As String
Dim IntegerResult As Integer

IntegerNumber = 2564 - 0.5
IntegerResult = CInt(IntegerNumber)
MsgBox IntegerResult

End Sub

It should give the result as 2564, not 2565.

VBA String to Integer Example 1-1

Example #2

Now, we will try and assign the number more than the limit of the Integer data type.

Code:

Sub CINT_Example2()

Dim IntegerNumber As String
Dim IntegerResult As Integer

IntegerNumber = 51456.785
IntegerResult = CInt(IntegerNumber)
MsgBox IntegerResult

End Sub

We have assigned the “IntegerNumber = 51456.785” more than the Integer data type limit. So now, if we try to run the code, it will throw an overflow error in VBAVBA Overflow Error or «Run Time Error 6: Overflow» occurs when the user inserts a value that exceeds the capacity of a specific variable’s data type. Thus, it is an error that results from the overloading of data beyond the desired data type limit of the variable.read more.

Example 2

Whenever the provided number is more than the Integer data type, let us show the simple message box saying, “Number is More Than the Limit of the Integer Data Type.”

Code:

Sub CINT_Example2()

Dim IntegerNumber As String
Dim IntegerResult As Integer

IntegerNumber = 51456.785
On Error GoTo Message:
IntegerResult = CInt(IntegerNumber)

Message:
 If Err.Number = 6 Then MsgBox IntegerNumber & " 
 is More Than the Limit of the Integer Data Type"
End Sub

It will show the message below whenever the provided number is outside the Integer data type range.

Example 2-1

Example #3

Now, we will try to assign the value which is not numeric.

Sub CINT_Example2()

Dim IntegerNumber As String
Dim IntegerResult As Integer

IntegerNumber = "Hello"
IntegerResult = CInt(IntegerNumber)
MsgBox IntegerResult

End Sub

We have assigned the value “Hello,” which is not numeric. It causes a “Type Mismatch ErrorWhen we assign a value to a variable that is not of its data type, we get Type mismatch Error or Error code 13. For example, if we assign a decimal or long value to an integer data type variable, we will get this error (Error Code 13) when we run the code.read more”.

Example 3

Instead of showing the error like this, let us put a simple information message box in front of the user. The below code will put the message box saying, “The Provided Expression Value is Non-Numeric, So, cannot be converted.”

Code:

Sub CINT_Example2()

Dim IntegerNumber As String
Dim IntegerResult As Integer

IntegerNumber = "Hello"
On Error GoTo Message:
IntegerResult = CInt(IntegerNumber)

Message:
 If Err.Number = 13 Then MsgBox IntegerNumber & " : 
 The Provided Expression Value is Non-Numeric, So cannot be converted"
End Sub

It will show the message box below.

Example 3-1

Things to Remember

  • The CINT function converts the value from another data type to an Integer data type.
  • Integers can hold values from -32768 to 32767. Anything above these numbers will cause an “Overflow” error.
  • Only string data type contains numerical data that will convert to an Integer data type.

You can use the CInt function in VBA to convert a text string to an integer.

Here are two common ways to use this function in practice:

Method 1: Convert String to Integer in VBA

Sub ConvertStringToInteger()

    Dim i As Integer

    For i = 2 To 11
        Range("B" & i) = CInt(Range("A" & i))
    Next i

End Sub

This particular macro will convert each string in the range A2:A11 to an integer and display the integers in the range B2:B11.

Method 2: Convert String to Integer in VBA (Only if String is a Number)

Sub ConvertStringToInteger()

    Dim i As Integer

    For i = 2 To 11
        If IsNumeric(Range("A" & i)) Then
            Range("B" & i) = CInt(Range("A" & i))
        Else
            Range("B" & i) = 0
        End If
    Next i

End Sub

This particular macro will convert each string in the range A2:A11 to an integer only if the string is a number. Otherwise, the string will be converted to a value of zero.

The following examples show how to use each method in practice.

Suppose we have the following column of values in Excel that are currently formatted as text strings:

Suppose we would like to convert each string to an integer and display the integers in column B.

We can create the following macro to do so:

Sub ConvertStringToInteger()

    Dim i As Integer

    For i = 2 To 11
        Range("B" & i) = CInt(Range("A" & i))
    Next i

End Sub

When we run this macro, we receive the following output:

Notice that each text string in column A has been converted to an integer and is displayed in column B.

Example 2: Convert String to Integer in VBA (Only if String is a Number)

Suppose we have the following column of values in Excel that are currently formatted as text strings:

Suppose we would like to convert each string to an integer only if the string is a number and display the integers in column B.

We can create the following macro to do so:

Sub ConvertStringToInteger()

    Dim i As Integer

    For i = 2 To 11
        If IsNumeric(Range("A" & i)) Then
            Range("B" & i) = CInt(Range("A" & i))
        Else
            Range("B" & i) = 0
        End If
    Next i

End Sub

When we run this macro, we receive the following output:

Notice that only the text strings in column A that are numbers are converted to integers in column B.

Otherwise, the text strings are simply converted to a value of zero.
