How to get unique data of google sheets to json with appscript? - json

Question

I'm getting values of the sheet in JSON format. My Sheet
I've added this code in appscript to get JSON:
var ss = SpreadsheetApp.openByUrl("Spreadsheet URL");
var sheet = ss.getSheetByName('Sheet1');
function doGet(e){
var action = e.parameter.action;
if(action == 'getItems'){
return getItems(e);
}
}
function getItems(e){
var records={};
var rows = sheet.getRange(2, 1, sheet.getLastRow() - 1,sheet.getLastColumn()).getValues();
data = [];
for (var r = 0, l = rows.length; r < l; r++) {
var row = rows[r],
record = {};
record['customerName'] = row[0];
record['docketNo']=row[1];
record['docketDate']=row[2];
record['destination']=row[3];
record['weight']=row[4];
data.push(record);
}
records = data;
var result=JSON.stringify(records);
return ContentService.createTextOutput(result).setMimeType(ContentService.MimeType.JSON);
}
Current JSON data:
[
{
"customerName":"cash",
"docketNo":"d87976489",
"docketDate":"2021-08-14T18:30:00.000Z",
"destination":"kanpur",
"weight":1
},
{
"customerName":"cash",
"docketNo":"d87976480",
"docketDate":"2021-08-12T18:30:00.000Z",
"destination":"kanpur",
"weight":1
},
{
"customerName":"abc",
"docketNo":"d87976482",
"docketDate":"2021-09-12T18:30:00.000Z",
"destination":"mumbai",
"weight":2
}
]
I want this JSON data:
[
{
"customerName":"cash",
"docketNo":"d87976489","d87976480",
"docketDate":"2021-08-14T18:30:00.000Z","2021-08-12T18:30:00.000Z",
"destination":"kanpur","kanpur",
"weight":1,1
},
{
"customerName":"abc",
"docketNo":"d87976482",
"docketDate":"2021-09-12T18:30:00.000Z",
"destination":"mumbai",
"weight":2
}
]
I have the same customer names therefore, I want unique data. I've searched many websites & videos but I didn't get one.
Please give me appscript code to get this data!

You can do it with some Javascript acrobatics
Sample:
function makeJsonUnique() {
var json = [
{
"customerName":"cash",
"docketNo":"d87976489",
"docketDate":"2021-08-14T18:30:00.000Z",
"destination":"kanpur",
"weight":1
},
{
"customerName":"cash",
"docketNo":"d87976480",
"docketDate":"2021-08-12T18:30:00.000Z",
"destination":"kanpur",
"weight":1
},
{
"customerName":"abc",
"docketNo":"d87976482",
"docketDate":"2021-09-12T18:30:00.000Z",
"destination":"mumbai",
"weight":2
}
]
var customerNames = json.map(e=>e.customerName)
var uniqueCustomerNames = [...new Set(customerNames)]
var newJSON =[]
uniqueCustomerNames.forEach(function(name){
var tempObj ={}
tempObj.customerName = name
var jsonSubsets = json.filter(function(obj){return obj.customerName == name})
tempObj.docketNo = jsonSubsets.map(obj=>obj.docketNo).join(",")
tempObj.docketDate = jsonSubsets.map(obj=>obj.docketDate).join(",")
tempObj.destination = jsonSubsets.map(obj=>obj.destination).join(",")
tempObj.weight = jsonSubsets.map(obj=>obj.weight).join(",")
console.log(JSON.stringify(tempObj))
newJSON.push(tempObj)
})
console.log(newJSON)
}
Used methods:
map()
filter()
...newSet()
push()
join()
