VBA code, extract Number from Text

During this post I will try to share VBA/Macro code to extract number from the text. Also, we will discuss the code to help you in understanding how to code in VBA. After all the aim is to make you enable write VBA code. Though in most of my post I write this at the end. This time I am advising you in middle to subscribe yourself to this blog. Also, your comments motivates us.

Let's move ahead with first understanding the application/scenario under which you can use this code. Take an example where you Microsoft Excel file where you have series of number where text is between number and you are only interested in numbers and not next. If the text is on fixed place you can remove that using LEFT() , RIGHT() or MIDDLE() function. But if the numbers and text are placed in cell where you are not sure number of text character and position of text. VBA code is solution to extract number.

VBA code to extract Number from Text

Function ExtractNumber(Target As Range) As Variant
Dim i As Integer
Dim str1 As String

For i = 1 To Len(Target)
    If IsNumeric(Mid(Target, i, 1)) Then
        str1 = str1 + Mid(Target, i, 1)
    End If
Next i

ExtractNumber = str1

End Function

Logic

For loop scan through the entire text like if you pass on the text Ae98rc243cd it will loop to entire text with one character at a time. LEN(Target) provide length to For Loop. Mid(Target,i, 1) picks one character at a time. Isnumeric(Mid(Target,i,1) checks if the character is numeric or not, if it's numeric then it concatenate/join the numbers into str1 using code str1 = str1+Mid(Target, i, 1).

I am sure this is not very difficult to understand. If you still face any issue, feel free to contact via email. I will try to reply all emails via email or via post.
