jsonToToon()

Convert JavaScript objects to TOON format

This function inspects your JavaScript object and automatically detects the type of each value (null, string, number, boolean, array, object). It then generates the appropriate TOON-formatted string.

Type Detection Rules

null → nl
string → s
number → n
boolean → b
Array → a
Object → j (JSON)

Example

JavaScript Input

const obj = {
  device_id: "DEVICE_PRO_01",
  battery: 87,
  temperature: 36.7,
  is_active: true,
  last_error: null,
  location: { lat: 12.9716, lng: 77.5946 },
  tags: ["iot", "health", "tracker"]
};

const toon = jsonToToon(obj);

TOON Output

device_id[1]{0:s}:
DEVICE_PRO_01

battery[1]{0:n}:
87

temperature[1]{0:n}:
36.7

is_active[1]{0:b}:
true

last_error[1]{0:nl}:
null

location[1]{0:j}:
{"lat":12.9716,"lng":77.5946}

tags[1]{0:a}:
["iot","health","tracker"]
