Since this appears to be a one time update, I would suggest that you just export your Excel worksheet to either a text file or xml file. To create an XML File, follow the instructions here:

You could read an XML file in using something like this:
Dim doc As New Xml.XmlDocument
Dim docpath As String = IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "Data.xml")
doc.Load(docpath)
For Each row As Xml.XmlNode In doc.GetElementsByTagName("Row")
Dim pid As Xml.XmlElement = row("pid")
Dim pid_value As Int32 = Int32.Parse(pid.InnerText)
Dim desc As Xml.XmlElement = row("description")
