I am aware that there are data entities available out of the box to import data to any table. However, for every new table, it requires data entity to be created. I would like to suggest creating a tool so that front end business user can import data by itself for any table without asking developer to create an entity. For example, user will select table and then fields out of this table on a form. Then export this template and import data using this template for selected table/fields without creating any object in the backend. Based on table and fields, it can match template columns and import data into this table.
