Question

我是angular的新手，有一个来自Angular 6的POST请求的JSON响应，我想将JSON中的数据写入Excel。 JSON的结构如下：

[{
    "client_products": [
        {
            "price": 2,
            "part_number": "part1",
            "customer_code": "112233",
            "products": [
                {
                    "num_sub_products": 1,
                    "product": "dummy1",
                    "product_name": "Product1",
                },
                {
                    "num_sub_products": 1,
                    "product": "dummy2",
                    "product_name": "Product2",
                }
            ],
            "quarter": 1,
            "volume": 363,
            "year": 2018
        },
        {
            "price": 34,
            "part_number": "part1",
            "customer_code": "112233",
            "products": [
                {
                    "num_sub_products": 1,
                    "product": "dummy1",
                    "product_name": "Product1",
                },
                {
                    "num_sub_products": 1,
                    "product": "dummy2",
                    "product_name": "Product2",
                }
            ],
            "quarter": 2,
            "volume": 6764,
            "year": 2018
        }
    ],
},
{
    "client_products": [
        {
            "price": 3,
            "part_number": "part2",
            "customer_code": "998877",
            "products": [
                {
                    "num_sub_products": 1,
                    "product": "dummy3",
                    "product_name": "Product3",
                }
            ],
            "quarter": 1,
            "volume": 5756452,
            "year": 2018
        },
        {
            "price": 51,
            "part_number": "part2",
            "customer_code": "998877",
            "products": [
                {
                    "num_sub_products": 1,
                    "product": "dummy3",
                    "product_name": "Product3",
                }
            ],
            "quarter": 2,
            "volume": 43546,
            "year": 2018
        },
        {
            "price": 5,
            "part_number": "part2",
            "customer_code": "998877",
            "products": [
                {
                    "num_sub_products": 1,
                    "product": "dummy3",
                    "product_name": "Product3",
                }
            ],
            "quarter": 3,
            "volume": 74534,
            "year": 2018
        }
    ]
}]

Excel的结构看起来像所附的图像。 excel structure 我看过不同的第三方程序包，例如xlsx，但它们仅复制正确格式的表，而不复制上面的自定义结构。

编写CSV文件可能会获得最佳效果。有很多的javascript和angular模块可以帮助您解决这一问题。我尝试直接用javascript编写Excel格式，但结果不尽人意。

就结构而言，Excel（和CSV）格式不支持嵌套数据，因此您必须将代码中的JSON展平，以获取适合于以指定格式写入CSV文件的内容

顺便说一句，问题不仅仅是Angular问题，而是JavaScript问题，因此您可以考虑在问题中添加javascript标签。

从angular6中的JSON对象创建自定义的Excel结构
