JOLT Merging dissimilar elements - jolt

Here is my input
[{
"name": "LAST_UPDATE_DATE",
"value": 1075456461000
},
{
"name": "LAST_UPDATED_BY",
"value": {
"value": "BCw="
}
}]
Here is the expected output
[{
"name": "LAST_UPDATE_DATE",
"value": 1075456461000
},
{
"name": "LAST_UPDATED_BY",
"value": "BCw="
}]
Tried to add default fields so that I can compare further, but can't seem to create a node with a value already existing ( value: 1075456461000 )
[{
"operation": "modify-default-beta",
"spec": {
"*": {
"val" : null,
"value": {
"val" : null
}
}
}
}]
Any suggestions are appreciated.

After several hours of struggle here is what I came up with ....
[
{
"operation": "shift",
"spec": {
"*": {
"$": "&1.fieldname",
"#": "&1.val",
"value": "&1.value"
}
}
},
{
"operation": "remove",
"spec": {
"*": {
"*": {
"value": ""
}
}
}
},
{
"operation": "default",
"spec": {
"*": {
"value": null
}
}
},
{
"operation": "modify-default-beta",
"spec": {
"*": {
"value?": "#(1,val)"
}
}
},
{
"operation": "remove",
"spec": {
"*": {
"val": ""
}
}
}
]

Facing issue with JOLT transformation with nested array

I have a JSON input :
{
"id": "Root_ID",
"Item": [
{
"id": "ID_1",
"characteristic": [
{
"name": "char1",
"value": "PRE1"
},
{
"name": "char2",
"value": "2050-01-01"
}
]
},
{
"id": "ID_2",
"characteristic": [
{
"name": "char1",
"value": "PRE2"
},
{
"name": "char2",
"value": "2050-01-02"
}
]
}
]
}
which needs to be converted by using a Jolt transformation spec to the following output :
{
"id": "Root_ID",
"Item": [
{
"id": "ID_1",
"char1": "PRE1",
"char2": "2050-01-01"
},
{
"id": "ID_2",
"char1": "PRE2",
"char2": "2050-01-02"
}
]
}
Currently, I'm using this spec :
[
{
"operation": "shift",
"spec": {
"id": "id",
"Item": {
"*": {
"characteristic": {
"*": {
"name": {
"char1": {
"#(2,value)": "item[#3].char1"
},
"char2": {
"#(2,value)": "item[#3].char2"
}
}
}
}
}
}
}
}
]
which does not produce the desired result.
Can you please help me prepare a correct spec to handle this issue ?
Edit : What if I'd like to get the following JSON result ?
{
"id": "Root_ID",
"Item": [
{
"id": "ID_1",
"char1": "PRE1"
},
{
"id": "ID_2",
"char1": "PRE2",
"char2": "2050-01-02"
}
]
}
You can use the following shift transformation spec in which #value and #name are matched reciprocally such as
[
{
"operation": "shift",
"spec": {
"id": "&",
"Item": {
"*": {
"id": "&2[&1].&",// you can reduce two levels based on the inner identifier 4,3 -> 2,1
"char*": {
"*": {
"#value": "&4[&3].#name" // &4 copies the literal "Item" after going four levels up the tree, [&3] generates array-wise result(array of objects) after going three levels up the tree to reach the level of the indexes of the "Item" array
}
}
}
}
}
}
]
Edit : You can alternatively use the following spec for the case in which you need to return char2 within the all objects but the first :
[
{
"operation": "shift",
"spec": {
"id": "&",
"Item": {
"0": {// stands for the first index
"id": "&2[&1].&",
"char*": {
"*": {
"name": {
"char1": {
"#2,value": "&6[&5].#3,name"
}
}
}
}
},
"*": {
"id": "&2[&1].&",
"char*": {
"*": {
"#value": "&4[&3].#name"
}
}
}
}
}
}
]

I am new to JOLT. And I'm having trouble navigating to the second array from inside the first.
Incomplete transformation that I tried:
[
{
"operation": "shift",
"spec": {
"Collection": {
"services": {
"*": "Collection.services[].&",
"#(3,lineId)": "lineId",
"#(3,promotions)":{
"*":
}
}
}
}
}
]
edit: Tried this now
[
{
"operation": "shift",
"spec": {
"Collection": {
"services": {
"*": "Collection.services[]",
// "*": "&",
"#(3,lineId)": "lineId",
"#(3,promotions)": {
"*": {
"Id": "Id"
}
}
}
}
}
}
]
I just have to figure out a way to move the Id list inside the objects in services array.
edit2:
[
{
"operation": "shift",
"spec": {
"Collection": {
"services": {
"*": {
"*": "Collection.services[&1].&",
"#(3,lineId)": "Collection.services[&1].lineId",
"#(3,promotions)": "Collection.services[&1].promotions"
}
}
}
}
}
]
I think this is the spec you're looking for?
[
{
"operation": "shift",
"spec": {
"lineId": "lineId",
"Collection": {
"services": {
"*": {
"#(3,promotions)": "Collection.services[&1].promotions",
"*": "Collection.services[&1].&"
}
}
}
}
}

Jolt giving values as root

Here's my input data :
[
{
"TEST1": "abcd",
"TEST2": "xyz",
"TEST3": "08"
},
{
"TEST1": "abcd",
"TEST2": "xyz",
"TEST3": "20"
}
]
Output
[
{
"TEST1": "root",
"TEST2": "xyz",
"TEST3": ["08","20"]
}
]
Expected Output
[
{
"TEST1": "abcd",
"TEST2": "xyz",
"TEST3": ["08","20"]
}
]
Jolt specs
[
{
"operation": "shift",
"spec": {
"": {
"TEST3": "#(1,TEST2).TEST3"

"spec": {
"": {
"$1": "[#2].TEST1",
"$": "[#2].TEST2",
"#.TEST3": "[#2].TEST3"
}
}
}
]
Can you please help me in achieving the excpected output
Check this spec
[
//Concat the TEST1 and TEST2 to temp
{
"operation": "modify-default-beta",
"spec": {
"*": {
"temp": "=concat(#(1,TEST1),':',#(1,TEST2))"
}
}
},
//Group the values by shifting TEST3
{
"operation": "shift",
"spec": {
"*": {
"TEST3": "#(1,temp)"
}
}
},
// Assign the keys to the node named key and value to the node nameed value
{
"operation": "shift",
"spec": {
"*": {
"#": "[#2].key",
"$": "[#2].value"
}
}
},
//Shift and assign the respective values to the TEST1, TEST2 and TEST3
{
"operation": "shift",
"spec": {
"*": {
"value": {
"*:*": {
"$(0,1)": "[&3].TEST1",

Jolt grouping together and including new tags

I have the following input JSON and want to group the sub jsons according to device name.(Device name has to be extracted from address). Also, i want to add new tags to the new arrays formed(Each array contains jsons having that type of device name only).
I've already tried below spec but the array Name name is appearing as deviceName instead of custom Parameter(I don't know how to provide custom name. for example i want the array name as "Parameters"). I'm not able to extract the device name from address field.(Device Name should come as "bee"/"honey"). Also, I want to add a new field which should be there once for the new array (and not for each element).
Input Json:
{
"CID": "AND",
"parameters": [{
"address": "abc:api:honey",
"name": "CH1"
},
{
"address": "abc:api:honey",
"name": "CH2"
},
{
"address": "abc:api:bee",
"name": "lat"
},
{
"address": "abc:api:bee",
"name": "long"
}
],
"rNo": 1232
}
Expected Output:
[{
"ID": "AND_1232",
"parameters": [{
"deviceName": "honey",
"name": "CH1",
"locoId": 1232,
"CID": "AND"
},
{
"deviceName": "honey",
"name": "CH2",
"locoId": 1232,
"CID": "AND"
}
],
"SpData": {
}
},
{
"ID": "AND_1232",
"parameters": [{
"deviceName": "bee",
"name": "lat",
"locoId": 1232,
"CID": "AND"
},
{
"deviceName": "bee",
"name": "long",
"locoId": 1232,
"CID": "AND"
}
],
"SpData": {
}
}]
Spec I tried:
[
{
"operation": "shift",
"spec": {
"parameters": {
"*": {
"#(2,CID)": "&2.[&1].CID",
"*": "&2.[&1].&",
"#(2,rNo)": "&2.[&1].locoId"
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"ID": "=concat(#(0,CID),'_',#(0,rNo))",
"parameters": {
"*": {
"deviceName": "=substring(#(1,address),8,11)",
"SpData": {}
}
}
}
}, {
"operation": "shift",
"spec": {
"parameters": {
"*": {
"deviceName": {
"*": {
"#2": "&[]"
}
}
}
}
}
}
]
The following will output desired results, each operation does the following respectively:
Add ID by concatenating CID and rNo
Add rNo and CID to all parameters and add deviceName (see here for details on device name splitting).
Group records by deviceName using object
Add ID to each group
Convert temporary grouping to array
Add default SpData
[
{
"operation": "modify-default-beta",
"spec": {
"ID": "=concat(#(1,CID),'_',#(1,rNo))"
}
},
{
"operation": "shift",
"spec": {
"ID": "&",
"parameters": {
"*": {
"address": {
"*:*:*": {
"$(0,3)": "parameters.[&3].deviceName"
}
},
"#(0,name)": "parameters.[&].name",
"#(2,rNo)": "parameters.[&].locoId",
"#(2,CID)": "parameters.[&].CID"
}
}
}
},
{
"operation": "shift",
"spec": {
"ID": "&",
"parameters": {
"*": {
"deviceName": {
"*": {
"#(3,[&2])": "tmp.&.parameters.[]"
}
}
}
}
}
},
{
"operation": "shift",
"spec": {
"tmp": {
"*": {
"#(2,ID)": "&1.ID",
"parameters": {
"#": "&2.parameters"
}
}
}
}
},
{
"operation": "shift",
"spec": {
"*": "[]"
}
},
{
"operation": "default",

"*": {
"SpData": {}
}
}

Set null if value is not exists, otherwise return existing value if exists in jolt

As shown in sample input, I have array of extension in each object. When extension doesn't consists subscription-type then output should be null as shown in output or else should consist existing value. Same should be applicable for language-type. Order of subscription-type and language-type is random in nature.
I have tried with spec but its not working
{
"operation": "modify-define-beta",
"spec": {
"*": {
"subscriptionType": {
"url": {
"myCoercedValue": "subscription-type",
"myStringValue": "subscription-type"
},
"value": {
"myCoercedValue": null,
"myStringValue": null
}
},
"languageType": {
"url": {
"myCoercedValue": "language-type",
"myStringValue": "language-type"
},
"value": {
"myCoercedValue": null,
"myStringValue": null
}
}
}
}
},
{
"operation": "shift",
"spec": {
"*": {
"extension": "[&1].extension",
"subscriptionType": "[&1].extension[]",
"languageType": "[&1].extension[]"
}
}
},
{
"operation": "shift",
"spec": {
"*": {
"extension": {
"*": {
"#url": {
"myStringValue": {
"subscription-type": {
"#(3,value.myStringValue)": "[&3].subscriptionType[]"
}
}
}
}
}
}
}
},
{
"operation": "shift",
"spec": {
"0": "[]"
}
}
]
Input:
[
{
"extension": []
},
{
"extension": [
{
"url": {
"myCoercedValue": "subscription-type",
"myStringValue": "subscription-type"
},
"value": {
"myCoercedValue": "free",
"myStringValue": "free"
},
"extension": []
}
]
},
{
"extension": [
{
"url": {

{

"myStringValue": "subscription-type"
},
"value": {
"myCoercedValue": "free",
"myStringValue": "free"
}
}
]
}
]
Output:
[ {
"subscriptionType" : [ null, "free", "free" ],
"language":[null,null,"en-US"]
} ]
Perhaps you want to get such a result? Please, try those spec and say what you want to modify.
