I am trying to jolt transformation spec for the below input :
{
"a": {
"serviceTesta": "Testa1",
"b": {
"serviceTestb": "Testb1",
"c": [
{
"name": "x",
"value": "100",
"desc": "this is description of X"
},
{
"name": "y",
"value": "200",
"desc": "this is description of y"
}
]
}
}
}
and the expected output is as below :
[
{
"Testa1_Testb1_x": "100",
"Testa1_Testb1_x_desc": "this is description of X"
},
{
"Testa1_Testb1_y": "100",
"Testa1_Testb1_y_desc": "this is description of y"
}
]
My Spec :
[
{
"operation": "shift",
"spec": {
"a": {
"b": {
"c": {
"*": {
"value": "#(4,serviceTesta).#(3,serviceTestb)#(1,name)"
}
}
}
}
}
}
]
I am new to jolt , tried different ways , but couldnt get desired output.
Any help is highly appreciated.
Thank you
You can achieve the desired result by doing secondary shift on your transformation:
Which uses the a combination of * and &n to build up your key.
[
{
"operation": "shift",
"spec": {
"a": {
"b": {
"c": {
"*": {
"value": "#(4,serviceTesta).#(3,serviceTestb).#(1,name)"
}
}
}
}
}
},
{
"operation": "shift",
"spec": {
"*": {
"*": {
"*": {
"#": "&3_&2_&1"
}
}
}
}
}
]

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].&"
}
}
}
}
}
]
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[]"
}
}
}
]
I have a complex JSON object (I've simplified it for this example) that I cannot figure out the JOLT transform JSON for. Does anybody have any ideas of what the JOLT spec file should be?
Original JSON
[
{
"date": {
"isoDate": "2019-03-22"
},
"application": {
"name": "SiebelProject"
},
"applicationResults": [
{
"reference": {
"name": "Number of Code Lines"
},
"result": {
"value": 44501
}
},
{
"reference": {
"name": "Transferability"
},
"result": {
"grade": 3.1889542208002064
}
}
]
},
{
"date": {
"isoDate": "2019-03-21"
},
"application": {
"name": "SiebelProject"
},
"applicationResults": [
{
"reference": {
"name": "Number of Code Lines"
},
"result": {
"value": 45000
}
},
{
"reference": {
"name": "Transferability"
},
"result": {
"grade": 3.8
}
}
]
}
]
Desired JSON after transformation and sorting by "Name" ASC, "Date" DESC
[
{
"Name": "SiebelProject",
"Date": "2019-03-22",
"Number of Code Lines": 44501,
"Transferability" : 3.1889542208002064
},
{
"Name": "SiebelProject",
"Date": "2019-03-21",
"Number of Code Lines": 45000,
"Transferability" : 3.8
}
]
I couldn't find a way to do the sort (I'm not even sure you can sort descending in JOLT) but here's a spec to do the transform:
[
{
"operation": "shift",
"spec": {
"*": {
"date": {
"isoDate": "[#3].Date"
},
"application": {
"name": "[#3].Name"
},
"applicationResults": {
"*": {
"reference": {
"name": {
"Number of Code Lines": {
"#(3,result.value)": "[#7].Number of Code Lines"
},
"Transferability": {
"#(3,result.grade)": "[#7].Transferability"
}
}
}
}
}
}
}
}
]
After that there are some tools (like jq I think) that could do the sort.
