separated by a comma.
All files loaded and saved by the Processing API use UTF-8 encoding.

It must be in the project's "data" folder. /* [ { "id": 0, "species": "Capra hircus", "name": "Goat" }, { "id": 1, "species": "Panthera pardus", "name": "Leopard" }, { "id": 2, "species": "Equus zebra", "name": "Zebra" } ] */ JSONArray values; void setup() { values = loadJSONArray("data.json"); for (int i = 0; i < values.size(); i++) { JSONObject animal = values.getJSONObject(i); int id = animal.getInt("id"); String species = animal.getString("species"); String name = animal.getString("name"); println(id + ", " + species + ", " + name); } } // Sketch prints: // 0, Capra hircus, Goat // 1, Panthera pardus, Leopard // 2, Equus zebra, Zebra
