From the outside, it would help if you were to provide an example of

what you want to encode, what you have tried, and what you got.

That will help list members provide better support.

cheers, r

Yes, because the first list is a list and not a plist.

If you go that route, I would rather wrap a string-stream with with-output-to-string and encode each individual plist to this stream (not the -to-string functions) to avoid string concatenation at the end.

I suggest using the explicit encoder for more control, but then you would need to change your p-lists slightly. I assume you want the plists to be json objects, and the list to be a json array.

Both these examples give the same result:

[{"a":"c","d":"c"},{"foo":true,"bar":false}

;; More json-javascriptish terminolgy (princ (json:with-explicit-encoder (json:encode-json-to-string '(:array (:object :a "c" :d "c") (:object :foo t :bar (:false))))))

;; More lispish terminology (princ (json:with-explicit-encoder (json:encode-json-to-string '(:list (:plist :a "c" :d "c") (:plist :foo t :bar (:false))))))

Or you could use the streaming encoder.
