Modify little JSON exporter in Google apps script

I have a google sheet that I use to export to a JSON file. For that I am using the code attached. It works fine, but the syntax of output is not right. Currently, this is the output: ***************CURRENT JSON OUTPUT ************************** [ { "id": "01", "lattitude": 47.81616, "longitude": 13.05476, "mapx": 4559, "mapy": 3037, "level": 2, "particles": 0, "rewardids": "[1,2]" }, { "id": "02", "lattitude": 47.81378, (...) **************and so on ***************************************** instead, I need output to look like this: ***************DESIRED OUTPUT************************* [ {"ID":0}, {"LATITUDE":13.3498}, {"LONGITUDE":14.3498}, {"MAP_X":00}, {"MAP_Y":01}, {"LEVEL":0}, {"AUDIO":0}, {"PARTICLES":0}, {"REWARD_IDS":[1,2]} ], [ {"ID":1}, {"LATITUDE":13.3498}, (...) ****************** and so on ************************** So as said, you need to make the necessary modifications to the export script below. Please only write to me if you have good english communication skills. If this job works out, we can do more! Best Regards Tobias
