JSON is commonly used in modern applications for data storage and transfers. Pretty much all programming languages provide APIs to parse JSON. 

From SQL Server 2016 on wards, JSON functions are commonly supported. You can use JSON_VALUE function to extract data from JSON columns.

Refer to the following page about more details of JSON functions:

from JSON_STR;
