"how to convert string to array in mongodb?" Code Answer

you could try this:

db.collection.find().foreach( function (x) {   
    lines = x.address.split(",");
    obj = {};
    useraddresslist = [];
    lines.foreach( function (address){
        addressarray = address.replace(/^ss*/, '').replace(/ss*$/, '').split(" ");
        obj[addressarray[0]] = !isnan(parseint(addressarray[1])) ? parseint(addressarray[1]) : addressarray[1];        
    });
    obj.building = "";
    obj.intercom = "";
    useraddresslist.push(obj);
    x.useraddresslist = useraddresslist; // convert field to string
    db.collection.save(x);
});
