Hi @longweismile,

No, ArduinoJson doesn't support JSON5 at the moment.

Since several users asked to allow hexadecimal values (#1401, #1686), I plan on adding support for JSON5 input in the form of a new deserializeJson5() function.
However, I don't plan on adding JSON5 output.

Best regards,
Benoit
