I want to transform a JSON using JOLT, in the following way.:
Input of json file
{
"Document_No": "ANG4",
"LineNo10": {
"Type": 1,
"Customer_No_": "1"
},
"LineNo11": {
"Type": 2,
"Customer_No_": "2"
},
"LineNo12": {
"Type": 3,
"Customer_No_": "3"
}
}
Desired output of json file
[
{
"Document_No":"ANG4"
"Type" : 1,
"Customer_No_" : "1",
"Line_No" : "10"
},
{
"Document_No":"ANG4"
"Type" : 2,
"Customer_No_" : "2",
"Line_No" : "11"
},
{
"Document_No":"ANG4"
"Type" : 3,
"Customer_No_" : "3",
"Line_No" : "12"
}
]
I don't lack a lot, but i don't know what transformations add to get the desired output
my Jolt specificaton is below
[
{
"operation": "shift",
"spec": {
"LineNo*": {
"#": "&",
"$": "&.Line_No"
}
}
},
{
"operation": "shift",
"spec": {
"*": {
"#": "[]"
}
}
}
]
My output json file :
[ {
"Type" : 1,
"Customer_No_" : "1",
"Line_No" : "LineNo10"
}, {
"Type" : 2,
"Customer_No_" : "2",
"Line_No" : "LineNo11"
}, {
"Type" : 3,
"Customer_No_" : "3",
"Line_No" : "LineNo12"
} ]
Could anyone help me with this?
Spec
[
{
"operation": "shift",
"spec": {
"LineNo*": {
// copy Document_No down into the "LineNo" maps
"#(1,Document_No)": "&1.Document_No",
"$": "&1.Line_No",
"*": "&1.&"
}
}
},
{
// accumulate all the "built" LineNo's into an array
"operation": "shift",
"spec": {
"*": {
"#": "[]"
}
}
}

I am trying to convert below JSON into name value pair :
{
"Size": "2",
"done": "true",
"records": [
{
"Id": "a7g6s0000004GZuAAM",
"NN": "00096411.0",
"Name": "ISOLIN TRADE & INVEST",
"RecordType": {
"attributes": {
"type": "TestType"
},
"Name": "Term"
}
},
{
"Id": "a7g6s0000004GZzAAM",
"Number": "00096412.0",
"Name": "ISOLIN"
}
]
}
Expecting output JSON :
{
"Size" : "2",
"done" : "true",
"Items" : [ {
"Fields" : [ {
"Name" : "Id",
"Value" : "a7g6s0000004GZuAAM"
}, {
"Name" : "NN",
"Value" : "00096411.0"
}, {
"Name" : "Name",
"Value" : "ISOLIN TRADE & INVEST"
}, {
"Name" : "RecordType_Name",
"Value" : "Term"
} ]
}, {
"Fields" : [ {
"Name" : "Id",
"Value" : "a7g6s0000004GZzAAM"
}, {
"Name" : "Number",
"Value" : "00096412.0"
}, {
"Name" : "Name",
"Value" : "ISOLIN"
} ]
} ]
}
I am using below jolt spec but transformation of RecordType element is not as expected :
Jolt Spec :
[
{
"operation": "remove",
"spec": {
"records": {
"*": {
"attributes": " "
}
}
}
},
{
"operation": "shift",
"spec": {
"*": "&",
"records": {
"*": {
"*": {
"$": "Items.&2.[#2].Name",
"#": "Items.&2.[#2].Value"
}
}
}
}
},
{
"operation": "shift",
"spec": {
"*": "&",
"Items": {
"*": {
"*": "Items.[#2].Fields[]"
}
}
}
}
]
How can I transform this into required format ?
I think remove transformation is not needed, and better to index each Field.
The trick for the solution would be distinguish RecordType attribute from the others by use of
"RecordType": {"Name": "Field&2.&1\\_&"}
such as
[
{
"operation": "shift",
"spec": {
"*": "&",
"records": {
"*": {
"*": "Field&1.&",
"RecordType": {
"Name": "Field&2.&1\\_&"
}
}
}
}
},
{
"operation": "shift",
"spec": {
"*": "&",
"Field*": {
"*": {
"$": "Items[0].&2.[#2].Name",
"#": "Items[0].&2.[#2].Value"
}
}
}
}
]
I'm trying to understand how to remove the key and object layers for the below. Any help would be greatly appreciated. Trying to use a JOLT processor in NIFI to address this data change.
INPUT:
[ {
"rbr" : {
"fetchTime" : "2020-07-06T23:46:23.677Z",
"customMetadata" : {
"x" : "1",
"o2" : {
"x2" : "y"
}
}
},
"xyz": {
"fetchTime" : "2020-07-06T23:46:23.677Z",
"customMetadata" : {
"x" : "1",
"o2" : {
"x2" : "y"
}
}
}
}
]
desired output:
[
{
"fetchTime" : "2020-07-06T23:46:23.677Z",
"customMetadata" : {
"x" : "1",
"o2" : {
"x2" : "y"
}
},
"type": "rbr"
},
{
"fetchTime" : "2020-07-06T23:46:23.677Z",
"customMetadata" : {
"x" : "1",
"o2" : {
"x2" : "y"
}
},
"type": "xyz"
}
]
Can be done with simple shift operation
[
{
"operation": "shift",
"spec": {
"*": {
"*": {
"fetchTime": "[#2].fetchTime",
"customMetadata": "[#2].customMetadata",
"$": "[#2].type"
}
}
}
}
]
Edit 1
Can shift all the values from current level using "#": "[#3].&",
[
{
"operation": "shift",
"spec": {
"*": {
"*": {
"*": {
"#": "[#3].&",
"$1": "[#3].type"
}
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"type": "=firstElement(#(1,type))"
}
}
}
]
Iterate over the array, and for each obj create newObj like so:
objKey=Object.keys(obj)[0];
newObj=obj[objKey];
newObj.type=objKey;
and push into new array.
Trying to make a Jolt script that will put in a single number line, then a array of strings in one single array and a tag on the end of that array. These are the values that I have been working with.

JOLT SPEC This is what I have been working with that prints out the ListofStrings but this is the one that works stably.

Check this spec
[
//Converting list to Map
{
"operation": "shift",
"spec": {
"*": {
"ListofStrings": null,
"*": {
"#": "#1.number",
"#(1,ListofStrings)": "#1.list"
}
}
}
},
//Shift the number and list to the input array
{
"operation": "shift",
"spec": {
"*": {
"$": "input[#2].number",
"#(0,list)": "input[#2].List"
}
}
}, {
"operation": "default",
"spec": {
"app_id": "test",
"input": {
"*": {
"app_id": "test"
}
}
}
}
]
Edit 1
Add the ID node to the map using first shift operation "ID": null, and "#(1,ID)": "#1.ID". Then shift the ID node to the input array in the second shift operation "#(0,ID)": "input[#2].ID".
[
//Converting list to Map

I'm so close with this but afraid I do need a hand with a jolt transformation. I've done most of the work but can't get the last minute transformation working.
Here is my data:
{
"totalElements": 168,
"columns": {
"dimension": {
"id": "variables/daterangehour",
"type": "time"
},
"columnIds": [
"1"
]
},
"rows": [
{
"itemId": "119050300",
"value": "00:00 2019-06-03",
"data": [
120
]
},
{
"itemId": "119050805",
"value": "05:00 2019-06-08",
"data": [
98
]
},
{
"itemId": "119050923",
"value": "23:00 2019-06-09",
"data": [
172
]
}
]
}
}
This is my Jolt:
[{
"operation": "shift",
"spec": {
"rows": {
"*": {
"value": "[&1].date",
"data": "[&1].data"
}
}
}
}
]
It gives me this result:
[ {
"date" : "00:00 2019-06-03",
"data" : [ 120 ]
}, {
"date" : "22:00 2019-06-09",
"data" : [ 307 ]
}, {
"date" : "23:00 2019-06-09",
"data" : [ 172 ]
} ]
This causes my system issues, I actual need the data field like this:
[ {
"date" : "00:00 2019-06-03",
"data" : "120"
}, {
"date" : "05:00 2019-06-08",
"data" : "98"
} ]
How do I pluck the item out of the array / square brackets? It will only ever be one item in there.
You should go deeper and take value. Is it clear for you?
[
{
"operation": "shift",
"spec": {
"rows": {
"*": {
"value": "[&1].date",
"data": {
"*": "[&2].data"
}
}
}
}
}
]
And if you need Strings add this:
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"data": "=toString"
}
}
}
I need to perform a Jolt transformation on the below example json:
Input
[
{
"DOCUMENT_HEADER_ID": "29120",
"Descrizione": "GAS",
"PrezzoTotale": "8.51"
},
{
"DOCUMENT_HEADER_ID": "29120",
"Descrizione": "IMPOSTE",
"PrezzoTotale": "7.25"
},
...
]
I need to trasform to
{
"DOCUMENT_HEADER_ID" : "29120",
"invoice" : [
{
"DOCUMENT_HEADER_ID" : "29120",
"Descrizione" : "GAS",
"PrezzoTotale" : "8.51"
}, {
"DOCUMENT_HEADER_ID" : "29120",
"Descrizione" : "IMPOSTE",
"PrezzoTotale" : "7.25"
},
...
]
}
Using this spec
[
{
"operation": "shift",
"spec": {
"#": "invoice"
}
}
]
I have this output:
{
"invoice" : [ {
"DOCUMENT_HEADER_ID" : "29120",
"Descrizione" : "GAS",
"PrezzoTotale" : "8.51"
}, {
"DOCUMENT_HEADER_ID" : "29120",
"Descrizione" : "IMPOSTE",
"PrezzoTotale" : "7.25"
},
...
]
}
but I can not figure out how to extract the value of DOCUMENT_HEADER_ID from the first element of original array
Can do it in a single shift.
[
{
"operation": "shift",
"spec": {
"#": "invoice",
"0": {
"DOCUMENT_HEADER_ID": "DOCUMENT_HEADER_ID"
}
}
}
]
I found the correct spec
[
{
"operation": "shift",
"spec": {
"#": "invoice"
}
},
{
"operation": "shift",
"spec": {
"invoice": {
"0": {
"DOCUMENT_HEADER_ID": "DOCUMENT_HEADER_ID"
},
"#": "invoice"
}
}
}
]
If having to retrieve single element, data like :
"array_field": ["array_single_element"]
can use:
{
"operation": "modify-overwrite-beta",
"spec": {
"array_field": "=concat(#(1,array_field))",
"*": "=concat(#(1,&))"
}
}
