将数组转换为包含多行图像的csv

json2csv shopify csv python

maudulus · 技术社区 · 7 年前

我正在将数组转换为csv,以便快速导入项目进行购物。 According to Shopify ,导入时必须执行以下操作以添加多个图像:

插入新行(每张图片一行)。
复制并粘贴“手柄”。
复制+粘贴图像URL。

因此,第一个图像放在第一行,所有后续图像放在下面的行中。示例csv位于此处: https://help.shopify.com/csv/product_template.csv

因此,我想编程一些将循环通过一个数组的东西,它看起来像下面的(明显更长的除外),并将其转换为一个csv,将除第一个以外的所有照片放入一个新行。

var array = [
  {
    "brief": "Brief 1",
    "description": "Description 1",
    "photos": [
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example.jpg?0101010101010",
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example2.jpg?0101010101010",
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example3.jpg?0101010101010"
    ],
    "price": "145",
    "tags": [
      "tag1",
      "tag2",
      "tag3"
    ],
    "title": "Title 1"
  },
  {
    "brief": "Brief 2",
    "description": "Description 2",
    "photos": [
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example4.jpg?0101010101010",
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example5.jpg?0101010101010"
    ],
    "price": "150",
    "tags": [
      "tag4",
      "tag5",
      "tag6",
      "tag7",
      "tag8",
    ],
    "title": "Title 2"
  }
]

我通常用 json2csv 它看起来像下面这样,只是我不知道如何处理多行方面。

json2csv -i data_in.json -f title,description,price,etc -o data_out.csv

python也可能是一个不错的选择,如下所示 this post 但同样,多行方面令人困惑:

import csv
import json

x = """[
  {
    "brief": "Brief 1",
    "description": "Description 1",
    "photos": [
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example.jpg?0101010101010",
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example2.jpg?0101010101010",
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example3.jpg?0101010101010"
    ],
    "price": "145",
    "tags": [
      "tag1",
      "tag2",
      "tag3"
    ],
    "title": "Title 1"
  },
  {
    "brief": "Brief 2",
    "description": "Description 2",
    "photos": [
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example4.jpg?0101010101010",
      "https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example5.jpg?0101010101010"
    ],
    "price": "150",
    "tags": [
      "tag4",
      "tag5",
      "tag6",
      "tag7",
      "tag8",
    ],
    "title": "Title 2"
  }
]"""

x = json.loads(x)

f = csv.writer(open("example.csv", "wb+"))

# Write CSV Header, If you dont need that, remove this line
f.writerow(["title", "description", "price"])

for x in x:
    f.writerow([x["title"],
                x["description"],
                x["price"])

csv的输出行顶部如下(必须“运行代码段”才能将其作为表查看)-请注意,我没有尝试创建HTML表:

<style type="text/css">

这并不难。您的代码几乎是正确的(假设列是按您想要的方式排列的,并且假设您在中传递了有效的JSON,因为您的列有一个额外的逗号),您只需要添加一点:

for x in x:
    images = x["photos"]
    f.writerow([x["title"],
                x["description"],
                x["price"],
                images.pop(0) if images else None])
    while images:
        f.writerow([None, None, None, images.pop(0)])

简而言之,它是按顺序循环所有图像,并在新的、否则是空的行中打印它们。在原始代码上运行, example.csv 最后看起来像这样:

title,description,price
Title 1,Description 1,145,https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example.jpg?0101010101010
,,,https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example2.jpg?0101010101010
,,,https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example3.jpg?0101010101010
Title 2,Description 2,150,https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example4.jpg?0101010101010
,,,https://cdn.shopify.com/s/files/1/01/01/01/files/imgs-example5.jpg?0101010101010

很明显,如何将这些内容放入不同的列中 None S就是这样 csv.writer 使单元格为空,因此将其用作所有其他列的占位符。

如果这需要易于修改,我建议使用不同的方法。不过,这看起来像一个一次性转换脚本,所以一个快速、简单的黑客攻击就可以了。

几点注意事项

a if b else c 如果 b 计算结果为 True a False c
ary.pop(n) n ary
images len(images) == 0
while
