When using [pack] you should not feed the left-most inlet with data immediately \, but store a value \, e.g. in a [f] and bang the store \, with the left outlet of [json-decode].;

Boolean values of TRUE/FALSE will be translated to 1 or 0 \, float and integer values will be output as floats. Nested objects and arrays are output as strings \, that can be parsed. After the object is fully parsed \, the left outlet will issue a bang \, so that you can differenciate between subsequent objects. The messages will come as list key value. If the string cannot be decoded as JSON \, then the right outlet will output a bang.;
