Usage of JSON in mySQL

In the project I am working on, there is a **Booking** table. - There are 8 types of Bookings. - I have elected to have just one table - There are 12 common fields I could store the rest of the fields as columns, but I am thinking of using JSON storage (which I have never used). It will add complexity to the code (in terms of readability) to split the JSON in the JavaScript application for editing and then recombining. Can I get MySQL to do the splitting and combining of JSON fields?
