I'm not sure where JSON got involved in that, but if you can manage to use CBOR instead, it's just as happy with QByteArray as with QString (and round-trips them to QByteArray, IIRC). For details, see qtbase/src/corelib/serialization/qcborstream.h I've also no idea how well it plays with QSettings; hopefully you know enough to work it out from the QCbor API ...
