I have a question regarding the metafields. Is there a way a change the value_type from string to JSON_string using Liquid syntax? I know there are apps that can handle this but I would have to change it manually for every customer.
It would be great to handle this from the code, that would either
A) change the value_type from string to JSON_string
B) convert the string value to JSON_string format
The reason why I need JSON_string is to be able to access the information.
