I’ve worked for a major international company and I was for a while the only maintainer of a shitty request form in an excel file, sent worldwide to hundreds of people. As they wanted more and more specific functions the stuff grew to thousands of unholy VBA code lines and a huge hidden sheet of data.

That thing even had a fully custom language switch function for all dozens of field labels and their possible values.

I kinda hope they’re still using it (that wouldn’t surprise me) and that their whole workflow will crash and burn when Microsoft finally kills VBA.
