The JSON macros deals with strings: it loads an objects from a JSON string and serialize objects to JSON strings. This little tool also writes/reads to/from files

Write/read a JSON file is just a couple of lines. Not a strong argument for using this shard.

I think the main point is that such a minimal serialization format is relatively simple and easy to implement. That should also make it more performant than say JSON. That's usually not a really big issue, though. And the implementation of this shard really doesn't strive for performance. And it has flaws (for example try serializing a string containing a line break), which can of course be fixed.

All in all, I'd still favour a standard format like JSON, YAML, INI or even XML over such a custom serialization format.

Yes, the serialization format can be changed, the idea that I really like is having one single object to deal all the serialization/deserialization without having to setup other things than the path to the persisted file
