Split string inside json into mulitple parameters - json

Question

I have a JSON like this:
[
{
"id": "28573041|utm_source=vodafone&utm_medium=banner&utm_campaign=smartphones",
"date": "2022-05-03"
},
{
"id": "28573041|utm_campaign=Vodafone_uppers_2022",
"date": "2022-05-03"
}
]
I want to split these ids like:
before : - this is actual id;
before = - this is a property name for parameters;
after = - this is a property value;
I want to parse it and get this result:
{
{
"id" : "28573041",
"date" : "2022-05-03",
"utm_source" : "vodafone",
"utm_medium" : "banner",
"utm_campaign" : "smartphones"
},
{
"id" : "28573041",
"date" : "2022-05-03",
"utm_campaign" : "Vodafone_uppers_2022"
}
}
Parameters can be different after | and order is not guaranteed, but only possible 5 variants: -
utm_source
utm_medium
utm_campaign
utm_term
utm_content
Any ways to do it with JOLT or other NiFi tools?

Other solution in this case.
[
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"aux": "=split(\\|,#(1,id))",
"id": "=firstElement(#(1,aux))",
"newInfo": "=lastElement(#(1,aux))",
"auxFinal": "=split(&,#(1,newInfo))"
}
}
},

"#": "[#4].fields[].field"
}

}

Splitting by pipes and equality signs might be used along with distinguishin by #(..,id) qualifiers presuming that the provided id values are unique per each object such as 28573041 and 28573042 respectively
[
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"idd": "=split('\\|', #(1,id))",
"id": "#(1,idd[0])",
"idd1": "=split('&', #(1,idd[1]))"
}
}
},
{
"operation": "shift",
"spec": {
"*": {
"*": "#(1,id).&",
"idd1": {
"*": "#(2,id).ide&"
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"ide*": "=split('=', #(1,&))"
}
}
},
{
"operation": "shift",
"spec": {
"*": {
"*": "&1.&",
"ide*": {
"0": "&2.key[]",
"1": "&2.val[]"
}
}
}
},
{
"operation": "shift",
"spec": {
"*": {
"id": "&1.&",
"date": "&1.&",
"val": {
"*": {
"#": "&3.#(3,key[&])"
}
}
}
}
},
{
"operation": "shift",
"spec": {
"*": ""
}
}
]

Hi You can use following operations and split it with |,&,= and then shift the relative values and remove the extra attributes :
[
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"id_Or": "=split('\\|',#(1,id))",
"id": "#(1,id_Or[0])",
"id_without_Or": "#(1,id_Or[1])",
"id_And": "=split('&',#(1,id_without_Or))",
"attribute1": "#(1,id_And[0])",
"attribute11": "=split('=',#(1,attribute1))",
"attributev1": "#(1,attribute11[1])",
"attributev11": "#(1,attribute11[0])",
"attribute2": "#(1,id_And[1])",
"attribute12": "=split('=',#(1,attribute2))",
"attributev12": "#(1,attribute12[0])",
"attributev2": "#(1,attribute12[1])",
"attribute3": "#(1,id_And[2])",
"attribute13": "=split('=',#(1,attribute3))",
"attributev13": "#(1,attribute13[0])",
"attributev3": "#(1,attribute13[1])",
"attribute4": "#(1,id_And[3])",
"attribute14": "=split('=',#(1,attribute4))",
"attributev14": "#(1,attribute14[0])",
"attributev4": "#(1,attribute14[1])",
"attribute5": "#(1,id_And[4])",
"attribute15": "=split('=',#(1,attribute5))",
"attributev5": "#(1,attribute15[1])",
"attributev15": "#(1,attribute15[0])"
}
}
}, {
"operation": "shift",
"spec": {
"*": {
"*": "[&1].&",
"#attributev1": "[#2].#attributev11",
"#attributev2": "[#2].#attributev12",
"#attributev3": "[#2].#attributev13",
"#attributev4": "[#2].#attributev14",
"#attributev5": "[#2].#attributev15"
}
}
},
{
"operation": "remove",
"spec": {
"*": {
"id_Or": "",
"id_without_Or": "",
"id_And": "",
"attribute1": "",
"attribute2": "",
"attribute3": "",
"attribute4": "",
"attribute5": "",
"attribute11": "",
"attribute12": "",
"attribute13": "",
"attribute14": "",
"attribute15": "",
"attributev1": "",
"attributev11": "",
"attributev12": "",

"attributev13": "",
"attributev3": "",
"attributev14": "",
"attributev4": "",

}
