Please, complete following tasks:

1. Set up DB using provided mysql dump file. You may use provided docker-compose.yml if you like. But docker knowledge is not required.
   
2. Create a script to generate a JSON file, containing a nested items_categories data. Only ID and name fields are required in export.
   
3. Create a script to generate an Excel file, containing items_categories data. Only ID and name fields are required in export. Data hierarchy should be visualized.
   
   There is install.php script present, which was used to generate test-data. This script somewhat represents current state of codebase (sql.php is actually a part of a current system).
   

Run

docker-compose exec lap-stack php /var/www/html/export.php

Files will be created on the app/export folder
