InStr Function in Excel VBAThe VBA InStr function helps find the position of a given substring within a string. It returns the first occurrence of the substring in the form of an integer (output). A string is a series of characters or text supplied to the function in double quotation marks.
To get the first number in a string:Use the search() method to get the index of the first number in the string. The search method takes a regular expression and returns the index of the first match in the string. Access the string at the index, using bracket notation.
Extract Numbers from String in Excel (using VBA) Since we have done all the heavy lifting in the code itself, all you need to do is use the formula =GetNumeric(A2). This will instantly give you only the numeric part of the string.
InStr function finds the position of a specified substring within the string and returns the first position of its occurrence. For example, if you want to find the position of 'x' in 'Excel', using the Excel VBA InStr function would return 2.
Here is a lightweight and fast method that avoids regex/reference additions, thus helping with overhead and transportability should that be an advantage.
Public Function GetNumLoc(xValue As String) As Integer
For GetNumLoc = 1 To Len(xValue)
If Mid(xValue, GetNumLoc, 1) Like "#" Then Exit Function
Next
GetNumLoc = 0
End Function
Something like this should do the trick for you:
Public Function GetPositionOfFirstNumericCharacter(ByVal s As String) As Integer
For i = 1 To Len(s)
Dim currentCharacter As String
currentCharacter = Mid(s, i, 1)
If IsNumeric(currentCharacter) = True Then
GetPositionOfFirstNumericCharacter = i
Exit Function
End If
Next i
End Function
You can then call it like this:
Dim iPosition as Integer
iPosition = GetPositionOfFirstNumericCharacter("ololo123")
