how to merg two jsons into single json with primary key

[String]

Hi Team ,

we are reaching the two jsons and we need to merge into one json depends on primary key 

Json1=

[{"asset_details":"0f19a6518787d11089e3c8490cbb35bb","u_order":"1","chargeable":"true","amount":"","shipto_loc":"Finland","IO:49eb58f81ba9691009952f02604bcbd9":"false","total_qty":"","u_model_number":"3766B002","u_consumable":"4c61ce9e87d4a51089e3c8490cbb350b","u_price":"","product_name":"ab775db51b31951009952f02604bcbeb","max_qty":""},{"asset_details":"0f19a6518787d11089e3c8490cbb35bb","u_order":"11","chargeable":"true","amount":"","IO:6eebd0f81ba9691009952f02604bcbcc":"false","shipto_loc":"Finland","total_qty":"","u_model_number":"3766B","u_consumable":"4c61ce9e87d4a51089e3c8490cbb350b","u_price":"","product_name":"ab775db51b31951009952f02604bcbeb","max_qty":""}]

Json2=

[{"u_model_number":"3766B002","amount":"70”},{“u_model_number":"3766B","amount":"75"}]

Primary key is u_model_number in both the json

expected JSON as output :

[{"asset_details":"0f19a6518787d11089e3c8490cbb35bb","u_order":"1","chargeable":"true","amount":"70","shipto_loc":"Finland","IO:49eb58f81ba9691009952f02604bcbd9":"false","total_qty":"","u_model_number":"3766B002","u_consumable":"4c61ce9e87d4a51089e3c8490cbb350b","u_price":"","product_name":"ab775db51b31951009952f02604bcbeb","max_qty":""},{"asset_details":"0f19a6518787d11089e3c8490cbb35bb","u_order":"11","chargeable":"true","amount”:”75”,”IO:6eebd0f81ba9691009952f02604bcbcc":"false","shipto_loc":"Finland","total_qty":"","u_model_number":"3766B","u_consumable":"4c61ce9e87d4a51089e3c8490cbb350b","u_price":"","product_name":"ab775db51b31951009952f02604bcbeb","max_qty":""}]

we have to update the amount field with respective u_model_number(primary key)

Please guide me

Hi @String,

Here is a sample code(not tested)

var json1 = [{"asset_details":"0f19a6518787d11089e3c8490cbb35bb","u_order":"1","chargeable":"true","amount":"","shipto_loc":"Finland","IO:49eb58f81ba9691009952f02604bcbd9":"false","total_qty":"","u_model_number":"3766B002","u_consumable":"4c61ce9e87d4a51089e3c8490cbb350b","u_price":"","product_name":"ab775db51b31951009952f02604bcbeb","max_qty":""},{"asset_details":"0f19a6518787d11089e3c8490cbb35bb","u_order":"11","chargeable":"true","amount":"","IO:6eebd0f81ba9691009952f02604bcbcc":"false","shipto_loc":"Finland","total_qty":"","u_model_number":"3766B","u_consumable":"4c61ce9e87d4a51089e3c8490cbb350b","u_price":"","product_name":"ab775db51b31951009952f02604bcbeb","max_qty":""}];
var json2 = [{"u_model_number":"3766B002","amount":"70"},{"u_model_number":"3766B","amount":"75"}];

var json1Map = {};
for (var i = 0; i < json1.length; i++) {
  json1Map[json1[i].u_model_number] = json1[i];
}

for (var i = 0; i < json2.length; i++) {
  var key = json2[i].u_model_number;
  if (json1Map[key]) {
    json1Map[key].amount = json2[i].amount;
  }
}

var mergedJson = [];
for (var key in json1Map) {
  mergedJson.push(json1Map[key]);
}

gs.print(mergedJson) // result

I hope this helps!

Hi @Hemant Goldar  thanks for your quick reply ,am have taken your ref and written below code .but not getting the merge json 

var json1=mrvsjson;

var json2=inboundjson;

var json1Map = {};

for (var i = 0; i < json1.length; i++) {

  json1Map[json1[i].u_model_number] = json1[i];

}

for (var j = 0; j < json2.length; j++) {

  var key = json2[j].u_model_number;

  if (json1Map[key]) {

    json1Map[key].amount = json2[j].amount;

 json1Map[key]. u_price = json2[j].price;

  }

}

Please guid me 

var mergedJson = [];

for (var key1 in json1Map) {

  mergedJson.push(json1Map[key1]);

}

gs.info("final check"+JSON.stringify(mergedJson));

        return JSON.stringify(mergedJson);

    },

Hi @String,

try this code

var json1=mrvsjson;
var json2=inboundjson;
 
for (var i = 0; i < mrvsjson.length; i++) {
  for (var j = 0; j < inboundjson.length; j++) {
    if (mrvsjson[i].u_model_number === inboundjson[j].u_model_number) {
      mrvsjson[i].amount = inboundjson[j].amount;
    }
  }
}

gs.info("final check"+JSON.stringify(mrvsjson));

I hope this helps!
