Flashback to my first job. Coworker designed a giant complex web app with bazillion UI messages. Another coworker (in the Management) sent me the UI messages. As an Excel file.

I was tasked to manually convert the messages to a PHP data structure of some description (because this was 2002 and Excel files didn’t exactly lend themselves to scripting in Linux). Surprisingly, the management person did acknowledge my complaint that the conversion process was far more painful than necessary. Not that this helped, because soon after the startup got acquired and as far as I know the tech currently only exists in conceptual level in some big corporate vault or other.
