Meteor: How to structure Mongo data from Google Sheets - arrays

Question

The BSON data list contains very unneeded values as shown below. The problem am I having is returning an array subset from Mongo so that I could display it in a template using Meteor.
Mongo stores the data as such:
meteor:PRIMARY> db.ga_spreadsheet.find().pretty()
{
"_id" : "7YLifh9C6Gp8HPCTm",
"spreadsheet" : "NBATEST",
"header" : null,
"cells" : {
"1" : {
"1" : {
"row" : "1",
"col" : "1",
"value" : "name"
},
"2" : {
"row" : "1",
"col" : "2",
"value" : "position"
},
"3" : {
"row" : "1",
"col" : "3",
"value" : "salary"
& client/view.js does the pull request
GASpreadsheet = new Mongo.Collection('GASpreadsheet');
if (Meteor.isClient) {
Meteor.call("spreadsheet/fetch","1kdRtyhrvXN1aEf35NwtA8pzHfjc9-lNwV76CE_Zr_g");
spreadsheetData = GASpreadsheet.findOne({spreadsheet: 'NBATEST'})
Template.nba.helpers({
'player': function(){
var currentUserId = Meteor.userId();
return GASpreadsheet.find({ createdBy: currentUserId },
{ sort: {score: -1, name: 1} });
},
cellState: function(x, y) {
if(screenArray[x][y] === 1){
return 'live';
}
else {
return 'dead';
}
},
'selectedClass': function(){
var playerId = this._id;
var selectedPlayer = Session.get('selectedPlayer');
if(playerId == selectedPlayer){
return "selected"
}
},
'selectedPlayer': function(){
var selectedPlayer = Session.get('selectedPlayer');
return GASpreadsheet.findOne({ _id: selectedPlayer });
}
});
}
