Posting & reading JSON field in table on database

I’ve noticed in Navicat that you can add JSON in the a table:
For example:

Address (Table)
[street] (JSON)
[city] (JSON)
[state] (JSON)
[postocde] (JSON)

Is there a way to post these into the table from a normal form ?
Also can the data be retrieved from the table with JSON with the same way as normal tables?

@Teodor could you please give some advice on this ?
Or if anyone could help it would be appropriate

Thanks in advance
