> Unfortunately, none of this applies to Excel because Excel doesn't work well with revision control. Why? Because Excel is not a source file. It is a database coupled with code. [...] The path to enlightement is a more sophisticated revision control systems - ones that can understand Excel. This is where the author lost me. The "path to enlightenment" is not to build new VCS software. The solution is simply to stop coupling your database with your code. Embrace the Unix philosophy and stop perpetuating monolithic software. Excel is a spreadsheet editor. It was never designed to be a database. It can act as a quick-and-dirty database with minimal setup and training required. Sometimes that's all you need and Excel is a fine tool for those situations. But it has limitations. Stop trying to force Excel as the solution to all your problems and don't be afraid to learn a new tool once in a while.
