Key value pair from object array

Hi,
I would like to create the below outbound message from an incoming object array.

{
    "root": {
        "elementName": {
            "@attributeName": "attributeValue",
            "$": "elementValue"
        },
        "repeatedElement": [
            {
                "key": {
                    "@attr": "attr1",
                    "$": "key1"
                },
                "value": "value1"
            },
            {
                "key": {
                    "@attr": "attr2",
                    "$": "key2"
                },
                "value": "value2"
            }
        ]
    }
}

Any suggestion please on the repeated elements, attributes, and values?
Thanks,
Deepak Shaw

Done, check the pipeline and let me know if this works for you. Can be made with multiple mappers or a JSON Schema as well, but this is simpler in terms of snaps usage.

Hi @bojanvelevski ,
I have updated the message with the minimum required fields. Hopefully
Group_By Fields output0.json (489 Bytes)
it gives a better understanding.

It’s a bit confusing. repeatedElement it’s obviously the InvoiceLines object, but in your output sample, the objects contain only one key value pair:

 {
                "key": {
                    "@attr": "attr1",
                    "$": "key1"
                },
                "value": "value1"
     } 

While in the incoming data, one object contains four fields:

{
        "LineNumber": "1",
        "LineExtAmtExclTax": "7000",
        "Employee": "Marlon Mangila",
        "LineTax": "700"
      }

Quickly use those fields to manually populate this output object from above, just as a reference.

Hi @bojanvelevski ,
Just to clarify here are input & output messages:
input:

[
  {
    "Header": {
      "InvoiceNumber": "PRP100418",
      "InvoiceDate": "29/04/2022",
      "PaymentTermsDescription": "Net 7 days",
      "CustomerRef": "C1381"
    },
    "InvoiceLines": [
      {
        "LineNumber": "1",
        "LineExtAmtExclTax": "7000",
        "Employee": "Marlon Mangila",
        "LineTax": "700"
      },
      {
        "LineNumber": "2",
        "LineExtAmtExclTax": "800",
        "Employee": "Elin Joe",
        "LineTax": "150"
      }
    ]
  }
]

output:

{
    "Invoice": {
        "InvoiceNumber": {
            "@attributeName": "PRP100418",
            "$": "C1381"
        },
        "InvoiceLines": [
            {
                "LineNumber": {
                    "@LineExtAmtExclTax": "7000",
                    "$": "1"
                },
                "value": "Marlon Mangila"
            },
            {
                "LineNumber": {
                    "@LineExtAmtExclTax": "8000",
                    "$": "2"
                },
                "value": "Elin Joe"
            }
        ]
    }
}

Looking forward to your suggestion.

Hi @bojanvelevski , Amazing 🙂 it’s working as expected.
Can you please explain a bit about the code you have written in the map i.e.

$InvoiceLines.map(x=>{"LineNumber":{"@LineExtAmtExclTax":x.LineExtAmtExclTax,"$":x.LineNumber},"value":x.Employee})

Many thanks for your help,
Deepak Shaw.
