@joepie91 I've voted for the 'decode'/'encode' pairs, but I also might be a little biased: I've already worked with 'decodeCBOR'/'encodeCBOR' style libraries.
On a second thought, I find the 'decode'/'encode' fits particularly well for binary formats (such as CBOR), while for text encodings (like JSON) I have a much softer preference for one or another.
@joepie91 I'm used to serialize/deserialize

I'd use "parse" and "format", but "stringify" is fine too.
I wouldn't use "encode" and "decode" since JSON is not an encoding.
