$data[] = array(
        'sku' => $record["sku"],
        'product_type' => $record['is_simple'],
        'url_key' => $record["url_key"],
        'attribute_set_code' => $record["attribute_set_code"],
        'product_websites' => "base",
        'categories' => $record["categories"],
        'name' => $record["name"],
        'description' => $record["description"],
        'short_description' => $record["short_descritpion"],
        'product_online' => 1,
