> An excel spreadsheet is usually easily auditable.

What does this sentence mean? Virtually no part of excel is easily auditable, at best you can see "this file was changed by xyz at a:b:c" identifying the cells that have changed between versions wouldn't even be easy.

All versions of Excel from 2013 and onward come with a tool that lists out cell by cell differences between two spreadsheets, called Spreadsheet Compare [0].

It lists side-by-side differences in hardcoded values, formula changes, calculated value changes, and even changes in VBA code. The list of changes can then be dumped out to a text file.

Default Excel installations also include the Inquire add-in which allows you to perform the comparison within Excel itself.
