Laravel Nova - JSON

Hello all - I'm wondering if you could provide me with your thoughts on DB design.

I have a very large user table that I 'may' refactor into JSON. For instance, addresses, names, tel, emails and all.

Would this be ok, or doing the above effect the search functionality of Nova? My user table is growing very large. Around 50 fields, and more to add.

Thoughts?

Cheers
