Hello @remka,

Example:

String[][] hexFrame = { 
                      {"0xA00000", "0xB00000", "0xC00000", "0xD00000"},
                      {"0x000000", "0x100000", "0x200000", "0x300000"}
                      };

JSONObject jsonObject = new JSONObject();

jsonObject.put("fps",  60);
jsonObject.put("myHexFrame", hexFrame);

println(jsonObject);
println();

String s = jsonObject.toString();
s = s.replaceAll("\\s+", "");
println(s);

saveJSONObject(jsonObject, "data/new.json");

Output:

"myHexFrame": [
    [
      "0xA00000",
      "0xB00000",
      "0xC00000",
      "0xD00000"
    ],
    [
      "0x000000",
      "0x100000",
      "0x200000",
      "0x300000"
    ]
  ],
  "fps": 60
}

{"myHexFrame":[["0xA00000","0xB00000","0xC00000","0xD00000"],["0x000000","0x100000","0x200000","0x300000"]],"fps":60}
