I've used NPOI and it's quite simple to use:

Using Xlfile As FileStream = New FileStream(FileName, FileMode.Open, FileAccess.Read)
    Using XLBook As HSSFWorkbook = New HSSFWorkbook(Xlfile)
        Using XLSheet As NPOI.SS.UserModel.Sheet = XLBook.GetSheetAt(0)

            Dim CurrentRow As NPOI.HSSF.UserModel.HSSFRow
                        Dim CurrentCell As NPOI.SS.UserModel.Cell
                        Dim RowEnum As IEnumerator = XLSheet.GetRowEnumerator()

            While RowEnum.MoveNext
                          If (RowEnum.Current IsNot Nothing) Then
                              CurrentRow = TryCast(RowEnum.Current, NPOI.HSSF.UserModel.HSSFRow)
                    Select Case CurrentCell.CellType
                        Case NPOI.SS.UserModel.CellType.STRING
                            ' CurrentCell.StringCellValue
                        Case NPOI.SS.UserModel.CellType.NUMERIC
                            ' CurrentCell.NumericCellValue.ToString()
                    End Select
            End While
        End Using
    End Using
    Xlfile.Close()
End Using
