I'm not familiar with any off the top of my head, but this reminded me of the book Designing Data Intensive Applications, here's one somewhat relevant snippet from it "JSON is less verbose than XML, but both still use a lot of space compared to binary formats. This observation led to the development of a profusion of binary encodings for JSON (MessagePack, BSON, BJSON, UBJSON, BISON, and Smile, to name a few) and for XML (WBXML and Fast Infoset, for example). These formats have been adopted in various niches, but none of them are as widely adopted as the textual versions of JSON and XML."
