Hi,

You can checkout the odoo populate method and see if it helps:  https://www.odoo.com/documentation/16.0/developer/reference/backend/performance.html?highlight=populate#module-odoo.tools.populate

If it is for testing purpose you can consider importing data from files from the Ui. Also from code side, you can import the data using csv files, you can check that too.

Thanks

Yeah, I know

You could try generation XML from the database records using your own script to capture what you wanna do as demo and that way you could add them manually on the Odoo UI

The same apply to do it from another source like JSON or YAML data, just to get it transformed into your XML Records

Also there are some other resources integrated directly into Odoo to populate the database:
