使用jq,如何将浅层对象数组的任意JSON编码转换为CSV?
这个站点上有很多问答,涵盖了对字段进行硬编码的特定数据模型,但是对于任何JSON,此问题的答案都应该有效,唯一的限制是它是具有标量属性的对象数组(无深度/复杂/子对象,如将它们展平是另一个问题)。结果应该包含一个标题行,给出字段名称。将优先选择保留第一个对象的字段顺序的答案,但这不是必须的。结果可以用双引号将所有单元格括起来,或者只将需要引用的单元格括起来(例如“ a,b”)。
例子
输入:
[
{"code": "NSW", "name": "New South Wales", "level":"state", "country": "AU"},
{"code": "AB", "name": "Alberta", "level":"province", "country": "CA"},
{"code": "ABD", "name": "Aberdeenshire", "level":"council area", "country": "GB"},
{"code": "AK", "name": "Alaska", "level":"state", "country": "US"}
]
可能的输出:
code,name,level,country
NSW,New South Wales,state,AU
AB,Alberta,province,CA
ABD,Aberdeenshire,council area,GB
AK,Alaska,state,US
可能的输出:
"code","name","level","country"
"NSW","New South Wales","state","AU"
"AB","Alberta","province","CA"
"ABD","Aberdeenshire","council area","GB"
"AK","Alaska","state","US"
输入:
[
{"name": "bang", "value": "!", "level": 0},
{"name": "letters", "value": "a,b,c", "level": 0},
{"name": "letters", "value": "x,y,z", "level": 1},
{"name": "bang", "value": "\"!\"", "level": 1}
]
可能的输出:
name,value,level
bang,!,0
letters,"a,b,c",0
letters,"x,y,z",1
bang,"""!""",0
可能的输出:
"name","value","level"
"bang","!","0"
"letters","a,b,c","0"
"letters","x,y,z","1"
"bang","""!""","1"
