How to Convert String to Integer in VBA (With Examples)

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.

Example 1: Convert String to Integer in VBA

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.
