Import not comming properly

[syampsijk]

My exported data is not comming in order,its coming a single character in a column

data.collection("Points”).find({'businessId': ‘shopname’ ,’_created_at':{$gt:d}}, { _id: false}).toArray(function(err, result) {

for(f=0;f<result.length;f++)
{
data = '{'+" Shop : ""+result[f].businessname+"", Points : "+result[f].point+'}';
data = data+" , " +data;
}

//data export
data = [data];
data = data.replace(/'/g, '');
var model = mongoXlsx.buildDynamicModel(data);
mongoXlsx.mongoData2Xlsx(data, model, function(err, data) {
console.log('File saved at:', data.fullPath);
});

This is what i am doing
but i guess my data comes as
['{shop : "shopname",Points : 10 }'];
Please help .i tried replace function but its not working .
Or is it any other issue,
