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:

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

MsgBox CLng("13.5")

The result is:

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"

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:

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

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

The result is:

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:

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:

String and Integer are common data types. But, often, as part of our data analysis, we may want to convert string data type variables to Integer data type. It is possible by using the CINT function in VBA.

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.

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.”

Examples of CINT Function in VBA

You can download this VBA String to Integer Excel Template here – VBA String to Integer Excel Template

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.

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.

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.

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 #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”.

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.

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.

Convert String to Number in VBA

In VBA code, converting numbers saved as text to real numbers is obligatory. We have many conversion options.

We can convert strings to numbers of the Byte, Integer, Long, Single, Double, Currency, and Decimal data types. We will discuss each conversion in detail with examples.

Convert String to Byte in VBA

We can easily transform a string into a number of the byte data type with the help of the following code.

# vba
byte = CByte(str)

We can use the CByte() function to achieve this conversion. The above statement has two items: CByte() and string.

CByte() function forces the string to change into a byte type. CByte() is often used to perform the internationally-aware string transformation to byte data type.

In simple terms, CByte() commonly distinguishes distinctive decimal/thousand separators and many currency options that hinge upon your computer’s location. The range that a byte data type can hold is 0 to 225. If your string does not fall in between this range, an error will occur.

Here is a macro example in which we have convertStr as an argument to convert a string to a byte.

# vba
Function convertStr(newStr As Variant)

    MsgBox (CByte(newStr))

End Function

Sub newFunc()
convertStr ("12")
End Sub

Output:

Convert String to Integer in VBA

With the help of the following statement, you can easily convert a string to a number of the integer data type. The syntax of this function is shown below.

# vba
CInt(newStr)

It is recommended to use the Clnt() function to change a string to an integer data type. This function forces the string to change into the integer data type.

If a string holds a fraction, this function will convert it into an integer. If the fraction is precisely 0.4, this function will change it to the closest even number.

For example:

# vba
0.4 will become 0.
1.6 and 2.4 both will become 2.
3.7 and 4.3 will become 4

Clnt() is often used to perform the internationally-aware string transformation into the integer data type. In simple terms, Clnt() commonly distinguishes distinctive decimal/thousand separators and many currency options that hinge upon our computer’s location.

The range between which an integer data type can hold numbers is -32,768 to 32,767. If your string does not fall in between this range, an error will occur.

Let’s go through an example and use the CInt() function as shown below. This example sets newStr as an argument to change a string into an integer, as shown below.

# vba
Function convertToInteger(newStr As Variant)

    MsgBox (CInt(newStr))

End Function

Sub newFunc()
convertToInteger ("12.5")
End Sub

Output:

Convert String to Long in VBA

We can use the CLng() function to achieve this conversion. The syntax of this function is shown below.

# vba
CLng(Str)

We can use the CLng() function when our goal is to change a string into several long data types. The items in this statement are CLng() and string.

This function forces a string to change into the long data type.

If a string holds a fraction, this function will round it. If the fraction is precisely 0.4, this function will change it to the closest even number, as shown below.

# vba
0.4 will become 0.
1.6 and 2.4 both will become 2.
3.7 and 4.3 will become 4

CLng() is often used to perform the internationally-aware string transformation to long data types. In simple terms, CLng() commonly distinguishes distinctive decimal/thousand separators and many currency options that hinge upon your computer’s location.

The range between which an integer data type can hold numbers is -2,147,483,648 to 2,147,483,647. If your string does not fall in between this range, an error will occur.

Let’s go through an example and use the CLng() function. In this example, we have set newStr as an argument to change a string into long, as shown below.

# vba
Function convertToLong(newStr As Variant)

    MsgBox (CLng(newStr))

End Function

Sub newFunc()
convertToLong ("15.7")
End Sub

Output:

Long data type differs from integer data type by only one thing. Larger numbers are acceptable in long data types.

But there wasn’t enough memory in the old days, and it was not recommended to use long data types.

In modern times, memory is no longer a problem. We can use the long data type instead of an integer.

Convert String to Single in VBA

We can easily transform a string into a number of a single data type with the help of the following syntax, as shown below.

# vba
CSng(str)

We can use the CSng() function to achieve this conversion. There are two items in the above statement, CSng() and string.

This function forces a string to change into a single data type.

CSng() is often used to perform the internationally-aware string transformation to a single data type. CSng() commonly distinguishes distinctive decimal/thousand separators and currency options that hinge upon your computer’s location.

The range between which a single data type can hold floating-point numbers is

3.402823E38 to -1.401298E-45 when values are negative
1.401298E-45 to 3.402823E38 when values are positive

An error will appear if your string does not fall between this range. As shown below, let’s go through an example in which we set newStr as an argument to change a string into a single.

# vba
Function convertToSingle(newStr As Variant)

    MsgBox (CSng(newStr))

End Function

Sub newFunc()
convertToSingle ("1.3")
End Sub

Output:

Convert String to Double in VBA

With the help of the following statement, we can easily convert a string to several double data types. The syntax of this function is as shown below.

# vba
CDbl(str)

It is recommended to use the CDbl() function to change a string to a double data type. This function forces a string to change into the double data type.

CDbl() is often used to perform the internationally-aware string transformation to a double data type.

In simple words, CDbl() commonly distinguishes distinctive decimal/thousand separators and many currency options that hinge upon your computer’s location.

The range between which a double data type can hold floating-point numbers is below.

-1.79769313486231E308 to -4.94065645841247E-324 when values are negative.
4.94065645841247E-324 to 1.79769313486232E308 when values are positive.

An error will appear if our string does not fall between this range. As shown below, let’s go through an example in which we set newStr as an argument to change a string into a double.

# vba
Function convertToDouble(newStr As Variant)

    MsgBox (CDbl(newStr))

End Function

Sub newFunc()
convertToDouble ("1.345")
End Sub

Output:

Convert String to Currency in VBA

With the help of the following statement, you can easily convert a string to several currency data types. The syntax of the function is shown below.

# vba
CCur(newStr)

It is recommended to use the CCur() function to change a string to a currency data type. This function forces a string to change into the currency data type.

CCur() is often used to perform the internationally-aware string transformation to a currency data type.

It means CCur() commonly distinguishes distinctive decimal/thousand separators and many currency options that hinge upon your computer’s location. The currency data type can hold integers by 10,000.

As a result, a currency can hold 15 numbers to the left of the decimal point and four numbers to the right of the decimal point. So the range between which a currency can hold numbers is:
-922,337,203,685,477.5808 to 922,337,203,685,477.5807.

An error will appear if your string does not fall between this range.

As shown below, let’s go through an example in which we set newStr as an argument to change a string into a currency.

# vba
Function convertToCurrency(newStr As Variant)

    msgBox(CCur(newStr))

End Function

Convert String to Decimal in VBA

We can use the following statement to achieve this conversion.

# vba
CDec(newStr)

We can use the CDec() function when our goal is to change a string into several decimal data types. This function forces a string to change into the decimal data subtype of the Variant data type.

In simple words, CDec() will return a variant changed to the Decimal subtype.

CDec() is often used to perform the internationally-aware transformation of a string to a decimal data type. It means CDec() commonly distinguishes distinctive decimal/thousand separators and many currency options that hinge upon your computer’s location.

The decimal data type can carry integers having variable power of 10. The power denotes the number of digits that can be present to the right of the decimal point.

The range in which decimals can hold values is shown below.

When the scale is 0, that is no decimal present the range is from 79,228,162,514,264,337,593,543,950,335 to 79,228,162,514,264,337,593,543,950,335.
When there are 28 decimal places, the biggest and smallest values are +7.9228162514264337593543950335 and -7.9228162514264337593543950335.
The smallest values containing no zero values are -0.0000000000000000000000000001 and 0.0000000000000000000000000001.

As shown below, let’s go through an example in which we set newStr as an argument to change a string into a decimal.

# vba
Function convertToDecimal(newStr As Variant)

    msgBox(CDec(newStr))

End Function

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.

Note: You can find the complete documentation for the VBA Cint function here.

Data types in VBA

Like in some other programming languages, VBA uses data types to identify what variables it can store and how they are stored. Most of the data types in VBA define numeric values. Here is a brief list of numeric data types:

Data type	Storage	Range
Byte	1 byte	0 to 255
Integer	2 bytes	-32,768 to 32,767
Long	4 bytes	-2,147,483,648 to 2,147,483,647
Single	4 bytes	-3.402823E38 to -1.401298E-45 for negative values; 1.401298E-45 to 3.402823E38 for positive values
Double	8 bytes	-1.79769313486231E308 to-4.94065645841247E-324 for negative values; 4.94065645841247E-324 to 1.79769313486232E308 for positive values
LongLong	8 bytes	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Valid on 64-bit platforms only.
Currency	8 bytes	-922,337,203,685,477.5808 to 922,337,203,685,477.5807
Decimal	14 bytes	+/-79,228,162,514,264,337,593,543,950,335 with no decimal point; +/-7.9228162514264337593543950335 with 28 places to the right of the decimal

Since there are many numeric data types, there are many functions to convert a string into number in Excel VBA.

Functions to a convert string into number in Excel VBA

All conversion functions use the same syntax: Each requires a single string argument to convert into a number. For example:

Each function returns an error If the string argument either is not a numeric or is outside the range of the data type being converted.

CInt(«A») returns a type mismatch error, because the «A» is not a numeric value.

CByte(«1250») returns an overflow exception.

Function	Return type	Example
CByte	Byte	CByte(«65.75») returns 66
CCur	Currency	CCur(«$256,000.50») returns 256000.5
CDbl	Double	CDbl(128.239856 * 4.8 * 0.04) returns 24.622052352
CDec	Decimal	CDec(«15000000.5678») returns 15000000.5678
CInt	Integer	CInt(«1234.56») returns 1235
CLng	Long	CLng(«1,500,000.88») returns 15000001
CLngLng	LongLong	CLngLng(«1,250,500,000.88») returns 1250500001
CSng	Single	CSng(«5.67854») returns 5.67854

Bonus: Use IsNumeric function to verify value

To avoid type mismatch errors, you can use the IsNumeric function to check if the expression is numeric or not. The function returns Boolean value based on the expression. TRUE if the expression is numeric, FALSE otherwise.

Here is a sample function that can check the data first, and convert the it into an integer if it is numeric. If the argument is not a valid number, the function returns 0.

Function ConvertInt(arg As String) As Integer
 If IsNumeric(arg) Then ConvertInt = CInt(arg)
End Function
