Please help. I am trying to extract certain fields from the below input based on some condition ( list of name and match whose key value is "key2"). But not getting the proper result.
json Input:
{"schemas": [
{
"name": "myschema",
"tables": [
{
"name": "myname",
"alias": "temp_alias",
"keys": [
{
"name": "value1",
"key": "key1",
"match": "match_val"
},
{
"name": "value21",
"key": "key2",
"match": "match_val2"
},
{
"name": "value22",
"key": "key2",
"match": "match_val2"
},
{
"name": "value3",
"key": "key3"
},
{
"name": "value4",
"key": "key4"
}
]
}
]
}
]
}
Expected Output: list of name and match whose key value is "key2".
{"key2": [
{
"name": "value21",
"match": "match_val2"
},
{
"name": "value22",
"match": "match_val2"
}
]
}
I have used the below spec but it is giving all the keys in output.
[{
"operation": "shift",
"spec": {
"schemas": {
"*": {
"tables": {
"*": {
"keys": {
"*": {
"key": {
"key2": {
"#2": "&"
}
}
}
}
}
}
}
}
}
}
]
Check this spec,
[
{
"operation": "shift",
"spec": {
"schemas": {
"*": {
"tables": {
"*": {
"keys": {
"*": {
"key": {
"key2": {
"#2": "#2[]"
}
}
}
}
}
}
}
}
}
}
]

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 have my input defined as
{
"lineId": "1",
"Collection": {
"services": [
{
"Code": "TB",
"Type": [
"Data"
]
},
{
"Code": "MAGTB",
"Type": [
"Data"
]
}
]
},
"promotions": [
{
"Id": "1"
},
{
"Id": "2"
}
]
}
I would like to get my output as
{
"lineId": "1",
"Collection": {
"services": [
{
"Code": "TB",
"Type": [
"Data"
],
"promotions": [
{
"Id": "1"
},
{
"Id": "2"
}
]
},
{
"Code": "TB2",
"Type": [
"Data"
],
"promotions": [
{
"Id": "1"
},
{
"Id": "2"
}
]
}
]
}
}
Any help would be appreciated.
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].&"
}
}
}
}
}
]
I have this input JSON:
{
"user": "123456",
"product": "television",
"category": "electronics",
"tag": "summer"
}
And this transformation:
[
{
"operation": "shift",
"spec": {
"product": {
"#(1,product)": "item",
"#(1,user)": {
"#2": "userBias"
}
},
"user": {
"#(1,user)": "user"
},
"category": {
"#category": "rules.[0].name",
"#(1,category)": "rules.[0].values[0]"
},
"tag": {
"rules": "rules",
"#tag": "rules.[1].name",
"#(2,tag)": "rules.[1].values[0]"
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"userBias?": "=toInteger"
}
}
]
Which works fine and produces the following JSON:
{
"item": "television",
"userBias": 2,
"user": "123456",
"rules": [
{
"name": "category",
"values": [
"electronics"
]
},
{
"name": "tag",
"values": [
"summer"
]
}
]
}
If from the input though I delete "category": "electronics" so it becomes:
{
"user": "123456",
"product": "television",
"tag": "summer"
}
Then i get back the following result:
{
"item": "television",
"userBias": 2,
"user": "123456",
"rules": [
null,
{
"name": "tag",
"values": [
"summer"
]
}
]
}
The problem with the above is that it contains a null element inside the array and I do not know how to get rid of it. I have tried with recursivelySquashNulls but it does not work.
Also basically what am looking for is if both category and tag exist then tag should go to rules[1] if only tag exists then tag should go to rules[0].
Thanks in advance,

Because you specify tag and category elements individually. Rather, prefer putting them into the category rest by combining them under asterisked key notation such as
[
{
"operation": "shift",
"spec": {
"product": {
"#(1,product)": "item",
"#(1,user)": {
"#2": "userBias"
}
},
"user": {
"#(1,user)": "user"
},
"*": {
"$": "r[0].&.name",
"#(1,&)": "r[0].&.values[]"
}
}
},
{
"operation": "shift",
"spec": {
"*": "&",
"r": {
"*": { "*": "rules" }
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"userBias?": "=toInteger"
}
}
]
Result1 :
Result2(without "category": "electronics" pair for the Input) :
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"
}
}
},
{
"operation": "shift",
"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",
"$(0,2)": "[&3].TEST2"
}
},
"key": "[&1].TEST3"
}
}
}

I would like to move the recommendations array by row_id key inside the investors with the same row_id
Original Json
{
"investors": [
{
"row_id": 1,
"name": "AAAA"
},
{
"row_id": 2,
"name": "BBBB"
}
],
"recommendations": [
{
"row_id": "1",
"title": "ABC"
},
{
"row_id": "2",
"title": "CDE"
}
]
}
I've tried a lot of specs at https://jolt-demo.appspot.com with no success
Specs tried...
[{
"operation": "shift",
"spec": {
"investors": {
"*": "investors[]"
},
"recommendations": {
"#": "recommendations[]"
}
}
}]
Desired Json
{
"investors": [
{
"row_id": 1,
"name": "AAAA",
"recommendations":[{
"row_id": "1",
"title": "ABC"
}]
},
{
"row_id": 2,
"name": "BBBB",
"recommendations":[{
"row_id": "2",
"title": "CDE"
}]
}
]
}
This can be done in two stage shift
First shift groups everything based on row_id.
(I'd suggest running the first shift of its own to see what the output is)
Second shift uses that grouped output and formats results.
[
{
"operation": "shift",
"spec": {
"*": {
"*": {
"row_id": {
"*": {
"#2": "&.&4"
}
}
}
}
}
},
{
"operation": "shift",
"spec": {
"*": {
"investors": "investors.[#2]",
"recommendations": "investors.[#2].recommendations[]"
}
}
}
]
