Just in case this term is not well-known:
CBOR diagnostic notation was originally defined in Section 6 of RFC 7049 and has been extended in Appendix G of RFC 8610.

https://tools.ietf.org/html/rfc7049#section-6
https://tools.ietf.org/html/rfc8610#appendix-G

Every JSON text also is an instance of CBOR diagnostic notation, i.e., CBOR diagnostic notation is a strict superset of JSON.

A few tools support CBOR diagnostic notation, e.g.,

	gem install cbor-diag

… and then convert for example with

	diag2cbor.rb foo.diag >foo.cbor

(See below for more info.)

There is also support in https://crates.io/crates/cbor-diag-cli

gem install cbor-diag

gives you the tools:

cbor2diag.rb
cbor2json.rb
cbor2pretty.rb
cbor2yaml.rb
diag2cbor.rb
diag2pretty.rb
json2cbor.rb
json2pretty.rb

which do pretty much what you would expect them to do, given these
definitions:

"cbor" is binary CBOR.
"diag" is CBOR's diagnostic notation.
"json" is JSON.
"pretty" is the pretty-printed representation of binary CBOR as used by
cbor.me.).
"yaml" is YAML.

Output is to stdout, input from stdin or files given as command line
arguments). (json2cbor.rb also has a -v option.)
