Jolt specification to transform JSON array within array - json

Question

I'm trying to transform a JSON file into something that can later be transformed to csv or xml. My JSON file looks like this:
{
"meta": {
"contentType": "Response"
},
"content": {
"_type": "Response",
"data": {
"_type": "ObjectList",
"meta": {
"_type": "ObjectListMeta"
},
"DataObjects": [
{
"head": {
"fields": {
"id": {
"value": "24"
},
"name": {
"value": ""
}
}
},
"table": [
{
"number": 1,
"fields": {
"height": {
"value": 500,
"text": "500"
},
"average": {
"value": -2,
"text": "-2"
}
}
},
{
"number": 2,
"fields": {
"height": {
"value": 99999,
"text": "99999"
},
"average": {
"value": -5,
"text": "-5"
}
}
}
]
}
]
}
}
}
I want the output to look like this:
[
{
"id": "24",
"name": "",
"height": 500,
"average": -2
},
{
"id": "24",
"name": "",
"height": 99999,
"average": -5
}
]
I tried the following JOLT specification:
[
{
"operation": "shift",
"spec": {
"content": {
"data": {
"DataObjects": {
"*": {
"head": {
"fields": {
"id": {
"value": "[&4].id"
},
"name": {
"value": "[&4].name"
}
}
},
"table": {
"*": {
"fields": {
"height": {
"value": "[&5].height"
},
"average": {
"value": "[&5].average"
}
}
}
}
}
}
}
}
}
}
]
But I only get the following output:
[
{
"id": "24",
"name": "",
"height" : [ 500, 99999 ],
"average" : [ -2, -5 ]
}
]
Which is not exactly what I want. How do I have to modify my spec to get the output I need?

Answer 1

You can combine those attributes under the table list as having multiple respective objects for one head.fields object such as
[
{
"operation": "shift",
"spec": {
"content": {
"*": {
"DataObjects": {
"*": {
"table": {
"*": {
"#(2,head.fields.id.value)": "[&].id",
"#(2,head.fields.name.value)": "[&].name",
"#(0,fields.height.value)": "[&].height",
"#(0,fields.average.value)": "[&].average"
}
}
}
}
}
}
}
}
]
