How to use local JSON in ACF theme?
To start using the local JSON feature, simply create a new folder in your theme and name it acf-json. This folder must have permissions for the server to read and write (in most cases 755 will work well). Once this folder exists, each time you save a field group a JSON file will be created (or updated) with the field group and field settings.

Each time you save a field group a JSON file will be created (or updated) with the field group and field settings.
