Create a DataTable from an Excel sheet

Hi

The following code is used to create a DataTable in Eric Moreau's post at
http://emoreau.com/Entries/Articles/2010/12/Using-ADONet-SQL-Bulk-Copy-feature.aspx
I am trying to work out how to create a the same table from a spreadsheet like the one shown in the image
How would I do this?

    Private Function CreateDataSource(ByVal pLargeDataTable As Boolean) As DataTable
        Dim dt As New DataTable("Person")
        With dt
            .Columns.Add("ID", GetType(Integer))
            .Columns.Add("FirstName", GetType(String))
            .Columns.Add("LastName", GetType(String))

            'Add rows
            .LoadDataRow(New Object() {-1, "Joe", "Dalton"}, True)
            .LoadDataRow(New Object() {-2, "Jack", "Dalton"}, True)
            .LoadDataRow(New Object() {-3, "Willam", "Dalton"}, True)
            .LoadDataRow(New Object() {-4, "Averell", "Dalton"}, True)

            If pLargeDataTable Then
                Dim intID As Integer = 5
                Do While intID <= 100000
                    .LoadDataRow(New Object() {intID * -1, "FN" + intID.ToString, "Dalton"}, True)
                    intID += 1
                Loop
            End If
        End With

        Return dt
    End Function
