The answer to everything in my previous workplace was "another excel sheet" when we had a proper Django application with relational integrity and data validation. Showing them that a few clicks on a web form was easier than what they were used to - copy pasting data from one web page, pasting it back into an excel, reformatting it and uploading it, followed by a ton of data validation errors.
