extract specific set of digits from random strings in EXCEL VBA - string

Question

Disclaimer- my case is specific, and in my case my code works because I know the pattern.
I was looking for an answer everywhere, and the codes I tried were not quite what I was looking for, this is my solution if you are looking for a set of numbers.
In my case, I was looking for 7 digits, starting with digit 1 in a a column with random strings, some string had the number some others didn't.
The number will appear in these three scenarios "1XXXXXX", "PXXXXXXXX", "PXXXXXXXXX"(this has more digits because there is a slash).
Here are the examples of strings:

9797 Po 1743071 404440 Claude Gaudette Jose Luis Lopez

My Code
Sub getnum()
'i don't use explicit so i didn't declare everything
Dim stlen As String
Dim i As Integer
Dim arra() As String
Dim arran() As String
Orig.AutoFilterMode = False
Call BeginMacro
LastRow = Orig.Cells(Rows.Count, 1).End(xlUp).Row
Orig.Range("J2:J" & LastRow).Clear
'loop though column
For n = 2 To LastRow
celref = Orig.Cells(n, 4).Value
'split string on white spaces
arra() = Split(celref, " ")
'turn string to multiple strings
For counter = LBound(arra) To UBound(arra)
strin = arra(counter)
'remove white spaces from string
storage = Trim(strin)
lenof = Len(storage)
'if string has 9 characthers, check for conditions
If lenof = 9 Then
'position of first and last charachter
somstr = Mid(storage, 1, 1)
somot = Mid(storage, 9, 1)
If somstr = "P" Or somstr = "p" And IsNumeric(somot) = True Then
'removes Po or PO and keeps only 7 digits
storage = Right(storage, 7)
'stores in column J
Orig.Cells(n, 10).Value = storage
End If
ElseIf lenof = 10 Then
somstr = Mid(storage, 1, 1)
somot = Mid(storage, 10, 1)
'other conditions
If somstr = "P" Or somstr = "p" And IsNumeric(somot) = True Then
'removes Po or PO and keeps only 7 digits
storage = Right(storage, 7)
'stores in column J
Orig.Cells(n, 10).Value = storage
End If
End If
'eliminate comma within
arran() = Split(storage, ",")
If Orig.Cells(n, 10).Value <> storage Then
For counter2 = LBound(arran) To UBound(arran)
strin2 = arran(counter2)
storage2 = Trim(strin2)
'final condition if is 7 digits and starts with 1
If IsNumeric(storage2) = True And Len(storage2) = 7 Then
car = Mid(storage2, 1, 1)
If car = 1 Then
'stores in columns J at specific position
Orig.Cells(n, 10).Value = storage2
End If
Else
If isnumeric(orig.cells(n,10).value) =true and _
len(orig.cells(n,10).value = 7 then
orig.cells(n,10).value = orig.cells(n,10).value
else
Orig.Cells(n, 10).Value = "no po# in D"
End If
Next counter2
End If
Next counter
Next n
Call EndMacro
End Sub

Answer 1

you may try this
Option Explicit
Sub getnum()
Dim position As Variant
Dim cell As Range
With Worksheets("Orig") ' change it to your actual sheet name
With Intersect(.UsedRange, Columns("J"))
.Replace what:="P/O", replacement:="P/O ", lookat:=xlPart
For Each cell In .Cells
position = InStr(cell.Text, " 1")
If position > 0 Then cell.Value = Mid(cell.Value, position + 1, 7)
Next
End With
End With
End Sub

Answer 2

This code paste two formulas one in column G and one in column J). The first formula checks for a "P" in the first character of the cell in column 2 and if there is a "P" it extracts the last 7 characters in the string and puts them in column G. The second formula checks if there is not a "P" and if not extracts the last 7 characters in the string and puts them in column J.
Sub Extract()
Dim ws As Worksheet
Dim lRow As Long
Set ws = ThisWorkbook.Sheets("Sheet3")
lRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
ws.Range("G2:G" & lRow).Formula = "=IF(LEFT(B2)=""P"",(RIGHT(B2,7)),"""")"
ws.Range("J2:J" & lRow).Formula = "=IF(LEFT(B2)<>""P"",(RIGHT(B2, 7)),"""")"
End Sub

Answer 3

You may use the RegEx to extract the number in desired format.
Please give this a try...
Function Get10DigitNumber(ByVal Str As String) As String
Dim RE As Object
Set RE = CreateObject("VBScript.RegExp")
With RE
.Global = False
.Pattern = "1\d{6}"
End With
If RE.test(Str) Then
Get10DigitNumber = RE.Execute(Str)(0)
End If
End Function
Then if you want to use this function on the worksheet itself, assuming your string is in A2, try this...
=Get10DigitNumber(A2)
OR
You may use this function in another sub routine/macro like this...
Debug.Print Get10DigitNumber(<pass your string variable here>)
Edited Function:
Function Get10DigitNumber(ByVal Str As String) As String
Dim RE As Object, Matches As Object
Set RE = CreateObject("VBScript.RegExp")
With RE
.Global = False
.Pattern = "[Pp]?\/?[Oo]?(1\d{6})\b"
End With
If RE.test(Str) Then
Set Matches = RE.Execute(Str)
Get10DigitNumber = Matches(0).SubMatches(0)
End If
End Function
And use if as already described above.

Answer 4

After understanding what you were doing, I think this will work. Any feedback would be appreciated.
Dim cell As Range, LRow As Long
LRow = ActiveSheet.Cells(Rows.Count, 4).End(xlUp).Row
For Each cell In Range("D2:D" & LRow)
If cell.Value Like "*Po *" Then
cell.Offset(0, 6).Value = Split(cell.Value, " ")(2)
Else: cell.Offset(0, 6).Value = Split(cell.Value, " ")(1)
End If
Next cell
For Each cell In Range("J2:J" & LRow)
If Len(cell.Value) > 7 Then
cell.Value = Right(cell.Value, 7)
End If
Next
