hi, my code above works in converting a column to hyperlinks. as you can see, it's quite a bit inefficient as everytime i click the button, it goes back and converts everything to hyperlinks again, even those that are already hypelinks. please point me in the right direction. i need a way to detect the columns that already has a hyperlink the offset by 1 then convert the non hyperlink cell.
thanks in advance.

Just try to get the address from the cell and check to see if you get an error:
Dim url As String
Dim isLink As Boolean
For RITMRow = 2 To LastRow
On Error Resume Next
url = ws1.Range("A" & RITMRow).Hyperlinks(1).SubAddress
isLink = (Err.Number = 0)
On Error GoTo 0
If Not isLink Then
RITMstorage = ws1.Range("A" & RITMRow).Value
ws1.Range("A" & RITMRow).Hyperlinks.Add Anchor:=ws1.Range("A" & RITMRow), _
Address:="https://site.site.com/sc_req_item.do?sys_id=" & RITMstorage, _
ScreenTip:="Request Number", _
TextToDisplay:=RITMstorage
End If
Next RITMRow
