Have you heard of EDN? It's mostly used in Clojure and ClojureScript, as it is to Clojure what JSON is to JS.
If you need custom data types, you can use tagged elements, but that requires you to have functions registered to convert the data type to/from representable values (often strings).
It natively supports quite a bit more than JSON does, without writing custom data readers/writers.
I haven't, but it's an interesting format for sure.
I've found a more comprehensive documentation here. [1]
At first glance, I would say it's a bit more complex that it should for a "human readable" format.
