Hi, I have a use case, where we're getting JSON data in complicated fashion, i have translate this object as JSON array and now am unable to extract the key/value from the array, and also there is no guarantee that every time we'll receive the Tags.

 

Please suggest how we can extract this from array.

 

Input JSON :

[
{
"SourceId": "/Apple/bb842437dd4/sourceGroups/ALPHABAT/providers/Mobile.com/phone/isp",
"Tags": "Name\": \"OMapplication\",\"Owner\": \"Breily",
"Tagscopy": [
"Name\": \"OMapplication\"",
"\"Owner\": \"Breily"
],
"ResourceName": "omapps"
},
{
"SourceId": "/Apple/bb842437dd4/sourceGroups/ALPHABAT/providers/Mobile.com/phone/isp",
"Tags": "mobile-source-usage\": \"apple-cloud",
"Tagscopy": [
"mobile-source-usage\": \"apple-cloud"
],
"ResourceName": "omapps"
}
]

 

Need to do operation on "Tagscopy", we're getting random data in this.

Desired JSON :

[{
"SourceId": "/Apple/bb842437dd4/sourceGroups/ALPHABAT/providers/Mobile.com/phone/isp",
"Tags": "Name\": \"OMapplication\",\"Owner\": \"Breily",
"Name": "OMapplication",
"Owner": "Breily",
"ResourceName": "omapps"
},
{
"SourceId": "/Apple/bb842437dd4/sourceGroups/ALPHABAT/providers/Mobile.com/phone/isp",
"Tags": "mobile-source-usage\": \"apple-cloud",
"mobile-source-usage": "apple-cloud",
"ResourceName": "omapps"
}
]

 

Jolt Spec Used :

[
{
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"SourceIdcopy": "=split('/', @(1,SourceId))",
"Tagscopy": "=split(',', @(1,Tags))",
"SourceName": "=lastElement(@(1,SourceIdcopy))"
}
}
},
{
"operation": "remove",
"spec": {
"*": {
"SourceIdcopy": ""
}
}
},
{
"operation": "modify-default-beta",
"spec": {
"*": {
"*": "&",
"Tagscopy": {
"*": "&"
}
}
}
}
]
