vba - Checking for broken hyperlinks in Excel

Question

I have a large list of hyperlinks (plus a few cells of nonsense) that I need to check. I need to know which links are still active and which no longer exist or return a 404 (or other) Error. I have been using the advice in this entry: Sort dead hyperlinks in Excel with VBA? and it worked great in a small selection of links, some of which I deliberately broke myself. However, now that I try to use the same macro on my actual list of hyperlinks it won't work at all! I've manually checked a few and have found links with 404 errors. Again, when I deliberately mistype one of the addresses it will pick that up but it won't pick up any in the list that were broken already.

I'm totally new to macros and am really stumbling about in the dark here. Any help/advice would be very much appreciated!

Answer 1

I've been using this for a while and it has been working for me.

Sub Audit_WorkSheet_For_Broken_Links()

If MsgBox("Is the Active Sheet a Sheet with Hyperlinks You Would Like to Check?", vbOKCancel) = vbCancel Then

    Exit Sub

End If

On Error Resume Next
For Each alink In Cells.Hyperlinks
    strURL = alink.Address

    If Left(strURL, 4) <> "http" Then
        strURL = ThisWorkbook.BuiltinDocumentProperties("Hyperlink Base") & strURL
    End If

    Application.StatusBar = "Testing Link: " & strURL
    Set objhttp = CreateObject("MSXML2.XMLHTTP")
    objhttp.Open "HEAD", strURL, False
    objhttp.Send

    If objhttp.statustext <> "OK" Then

        alink.Parent.Interior.Color = 255
    End If

Next alink
Application.StatusBar = False
On Error GoTo 0
MsgBox ("Checking Complete!" & vbCrLf & vbCrLf & "Cells With Broken or Suspect Links are Highlighted in RED.")

End Sub
