Plugin to get DB Data in JSON format

Your software
My Mautic version is: 2.16.2
My PHP version is: 7.3

Your problem
My problem is:
Is there exist any Mautic plugin that would give data (from database) in JSON format? I am not interested in REST API which gives a subset of the actual data. I am looking for a plugin that will give the full data from database in JSON format.

I am looking to get collection of data from database in JSON format.

Some additional Information about the environment
DB Version: 10.1.44 (MariaDB)
ubuntu - 18.04
