TOON Data Types

Complete guide to every supported TOON type code

TOON uses single or two-letter codes to declare the type of each field. This allows toonToJson to parse values correctly and jsonToToon to detect types automatically.

nNumber87 or 36.7Integers and floats

bBooleantrue or falseLowercase only, case-sensitive

nlNullnullRepresents null/undefined values

jJSON Object{"a":1}Valid JSON object, auto-parsed

aArray[1,"a",true]Valid JSON array, auto-parsed

tdText/Date03042026120000Raw text, no parsing (good for date strings)
