使用 JQ 将 JSON 嵌套到 CSV

Question

我正在尝试将此 json https://pastebin.com/1ch1CzM4 转换为 csv，以便将其全部导入数据库，但我一直遇到错误。我得到的最接近的是

./jq -r '[.[]] | @csv'

但是这并没有起到作用，因为它是嵌套的。非常感谢任何帮助。

我试图让父母作为第一行，所以“地址、舒适组、check_in_time、check_out_time”，然后如果其中有一个 json，它只是 csv 中的一个平面 json 文本。

如果我尝试

jq -r '[[.address, .amenity_groups, .check_in_time, .check_out_time] | map(tostring) | @csv] | map(tostring) | @csv'

那么输出就是

"""140 Ancien Chemin De Berre, Lambesc"",""[{""""amenities"""":[""""Garden"""",""""Terrace""""],""""group_name"""":""""General""""}]"",""16:00:00"",""10:00:00"""

vs 想要的

address, amenity_groups, check_in_time, check_out_time
$json_of_address, $json_of_amenity_groups, 12, 12

Answer 1

似乎满足所述要求的解决方案是：

[.address, .amenity_groups, .check_in_time, .check_out_time]
| map(tostring)
| @csv

您可能希望避免盲目使用tostring，但至少它是通用的。

通用 JSON 到 CSV 转换

用于将任意 JSON 对象数组转换为 CSV 的 jq 过滤器 (json2csv) 位于：

jq: Object cannot be csv-formatted, only array

使用您的 JSON 对象流，您可以（例如）通过 -s 命令行选项像这样使用它：

map({address, amenity_groups, check_in_time, check_out_time})
| json2csv

使用 json2csv 输出

"address","amenity_groups_0_amenities","amenity_groups_0_group_name","amenity_groups_1_amenities","amenity_groups_1_group_name","amenity_groups_2_amenities","amenity_groups_2_group_name","amenity_groups_3_amenities","amenity_groups_3_group_name","amenity_groups_4_amenities","amenity_groups_4_group_name","amenity_groups_5_amenities","amenity_groups_5_group_name","check_in_time","check_out_time"
"140 Ancien Chemin De Berre, Lambesc","Garden|Terrace","General","null","null","null","null","null","null","null","null","null","null","16:00:00","10:00:00"
