I have an Excel workbook that pulls data from our intranet.  However, the URLs change and I am wondering if there is a way to loop through the URLS on the worksheet and return to the user an error message if any of them are broken - I want to do this before processing the data as there are 100's of URLs and if one fails, the user has to find it, fix it and start all over again.

There's plenty of applications doing this.   Any particular reason why you need to develop something for that?

Because this is a customized VBA program and has to be internal to it.

You can use this to check if it exist or not...

Function GetUrlStatus(argUrl)
    On Error Resume Next
    With CreateObject("msxml2.xmlhttp")
        .Open "GET", argUrl, False
        .send
        If Err Then
            GetUrlStatus = 9999 'to indicate server not found...
        Else
            GetUrlStatus = .Status
        End If
    End With
End Function

This does work, next step is to figure out how to loop through the array, but progress!  Thank you for being patient as I know it took a while for me to get back to this question.

Well, not much informations were given about the array.
Let's say that you got your URL's into Column A of Sheet1.  You could have this piece of code to check for the broken links, and set the status for every sites in Column B...

If you can give me more precision, i'll help.

Public Sub VerifyAllUrls()
    Dim sURL As String
    
    For Each cel In Sheet1.UsedRange.Rows.EntireRow
        sURL = cel.Cells(1, 1)
        cel.Cells(1, 2).Value = IIf(GetUrlStatus(sURL) <> 9999, "OK", "BROKEN")
    Next
    Sheet1.Columns.AutoFit
End Sub

Open in new window
