I agree with that. Modern software development has version control, unit tests, package managers, etc. Ideally we get support for some of those concepts in something that feels like a spreadsheet to the end user. (I'm not sure if it could ever be retrofitted to Excel)

As others have said, you can get version control with Excel by saving the file the SharePoint.

Some huge financial spreadsheets have sanity checks computations. With conditional coloring (turn this cell red if the sanity check fails) these can feel a lot like unit tests. However, these are mostly for business logic - so it's hard to see how a vendor could provide them.

In other words, it's not that excel doesn't have version control and unit tests - it's that the people who wrote excel spreadsheet sheets don't understand version control or unit tests.
