JQ 到 CSV 问题

Question

我之前在这里得到了一些关于 jq 到 csv 问题的帮助。我遇到了一个问题，一些 json 文件有一些额外的值会破坏 jq 命令

这里是json数据。修复部分是破坏 jq 命令的原因

[
    {
        "Name": "John Doe",
        "Car": [
            "Car1",
            "Car2"
        ],
        "Location": "Texas",
        "Repairs: {
            "RepairLocations": {
                "RepairsCompleted":[
                    "Fix1",
                    "Fix2"
                ]
            }
        }
    },
    {
        "Name": "Jane Roe",
        "Car": "Car1",            
        "Location": [
            "Illinois",
            "Kansas"
        ]
    }
]

这里是命令

def expand($keys):
    . as $in
    | reduce $keys[] as $k ( [{}];
        map(. + { 
            ($k): ($in[$k] | if type == "array" then .[] else . end)
        })
    ) | .[];
(.[0] | keys_unsorted) as $h
| $h, (.[] | expand($h) | [.[$h[]]]) | @csv

这是我想要得到的最终结果。此数据不是实际数据。

Name,Car,Location,Repairs:RepairLocation
John Doe,Car1,Texas,RepairsCompleted:Fix1
John Doe,Car1,Texas,RepairsCompleted:Fix2
John Doe,Car2,Texas,RepairsCompleted:Fix1
John Doe,Car2,Texas,RepairsCompleted:Fix2
Jane Roe,Car1,Illinois,
Jane Roe,Car1,Kansas,

对此的任何建议都会很棒。我正在努力弄清楚jq

Answer 1

可以使用similar question you already asked 的答案之一中所示的相同技术获得一个简单的解决方案。唯一的区别是在“修复”键不存在的情况下满足您的要求：

["Name", "Car", "Location", "Repairs:RepairLocation"],
(.[]
 | [.Name]
    + (.Car|..|scalars|[.])
    + (.Location|..|scalars|[.])
    + (.Repairs|..|scalars
       | [if . == null then . else "RepairsCompleted:\(.)" end]) )
| @csv

使用辅助函数避免重复

def s: .. | scalars | [.];

["Name", "Car", "Location", "Repairs:RepairLocation"],
(.[]
 | [.Name] 
    + (.Car|s)
    + (.Location|s) 
    + (.Repairs|s|map(if . == null then . else "RepairsCompleted:\(.)" end)))
| @csv
