)

type product struct {
        Productid string
        Productname string
        Unitcost float32
        Status string
        Listprice float32
        Attr1 string
        Itemid string
}

type grid struct {
        Total int
        Rows []product
}

func main() {
        var grid grid
        data, err := ioutil.ReadFile("datagrid_data1.json")
        if err != nil {
                fmt.Println("ReadFile:", err.Error())
        }
        json.Unmarshal(data, &grid)
        fmt.Println(grid)
        fmt.Println("----------------------------")
        b, _ := json.Marshal(grid)
        fmt.Println(string(b))
}
