Extract 5 Digit Number From a String with Excel-VBA - string

Question

I'm facing a problem as a non dev. I have a column in Excel that contains info as such:
46843 xxxx xxx x
xxxx 65483 xxxx
xxxx xxx 65432 xxxxx 4 xx
"x" being normal caracters.
What I want is to be able to extract only the numbers of five digits only.
I started something like this but struggle to put a loop so that it scans all the string:
Function test()
val_in = "rue 4 qsdqsd CURIE 38320 EYBENS"
Filte = Left(val_in, 5)
If IsNumeric(Filte) Then
test = Left(val_in, 5)
Else
sp1 = InStr(1, val_in, " ")
sp2 = InStr(sp1 + 1, val_in, " ")
spt = sp2 + sp1
If spt > 5 Then
extr = Mid(val_in, spt, 5)
End If
End If
End Function
How could I turn the part after "Else" into a loop so that it would scan every space of the string and extract only the numbers that contains 5 digits?

Answer 1

Using regex
Option Explicit
Public Function GetNumbers(ByVal rng As Range) As Variant
Dim arr() As String, i As Long, matches As Object, re As Object
Set re = CreateObject("VBScript.RegExp")
With re
.Global = True
.MultiLine = True
.IgnoreCase = False
.Pattern = "\b\d{5}\b"
If .test(rng.Value) Then
Set matches = .Execute(rng.Value)
ReDim arr(0 To matches.Count - 1)
For i = LBound(arr) To UBound(arr)
arr(i) = matches(i)
Next i
Else
arr(i) = rng.Value
End If
End With
GetNumbers = Join(arr, ",")
End Function
Data:
If there is more than one match a comma separated list is returned.

Sub TestMe()
Dim valIn As String
valIn = "rue 4 qsdqsd CURIE 38320 EYBENS 43443"
Dim i As Long
Dim splitted As Variant
splitted = Split(valIn)
For i = LBound(splitted) To UBound(splitted)
If IsNumeric(splitted(i)) And Len(splitted(i)) = 5 Then
Debug.Print splitted(i)
End If
Next i
End Sub
Considering that in your example you mean that the 5 digit numbers are splitted by space, the above works. It splits the string by space to an array and loops through the elements of the array. If the element is with 5 chars and is numeric, it prints it.
If the rule for the spaces is not something that one can count on, here is a different implementation:
Sub TestMe()
Dim valIn As String
valIn = "44244rue4qsdqsdCURIE383201EYBENS43443"
Dim i As Long
For i = 1 To Len(valIn) - 4
If IsNumeric(Mid(valIn, i, 5)) Then
Debug.Print Mid(valIn, i, 5)
End If
Next i
End Sub
It starts looping through the string, checking whether each 5 chars are numeric. When you have numeric 6 chars, it gives two results - 1 to 5 and 2 to 6. Thus 383201 is "translated" as the following 2:
38320
83201

Answer 3

If you have always space between words/numbers then this should do
Sub test()
Dim TestStr As String
Dim Temp As Variant
Dim i As Long, FoundVal As Long
TestStr = "rue 4 qsdqsd CURIE 38320 EYBENS"
Temp = Split(TestStr, " ")
For i = 0 To UBound(Temp)
If Len(Trim(Temp(i))) = 5 And IsNumeric(Temp(i)) Then
FoundVal = Temp(i)
MsgBox FoundVal
End If
Next i
End Sub

Answer 4

From the solution you are trying to apply (creating custom function in VBA) I understand that you actually need to use it in a formula.
To find number with five digits from cell A1 you can use the following formula without VBA:
=IF(ISERROR(FIND("0"&REPT("1",5)&"0",CONCAT(0+(ISNUMBER(-MID(" "&A1&" ",ROW(INDIRECT("1:"&LEN(A1)+2)),1))+0)))),"",MID(A1,FIND("0"&REPT("1",5)&"0",CONCAT(0+(ISNUMBER(-MID(" "&A1&" ",ROW(INDIRECT("1:"&LEN(A1)+2)),1))+0))),5))
To search for other number of digits change the three occurrences of number 5 to your desired digits count in the formula.
