I have published a JSON-stat (read & write) library for the Go language.
Features: Go-native, full round-trip: decode/encode, traverse, Dice subset, Unflatten+Transform, Builder, validate, net/http server, CLI.
I hope it is useful.
Programming languages currently supported in the JSON-stat ecosystem: JavaScript, Python, Java, Julia, PHP, R, WebAssembly, Rust and Go.
