I was recently asked in a class about comparing two spreadsheets – as you can in Word. I hadn’t heard of anything but guess what – as with so many Microsoft products – turns out that there was a tool to do that..called Spreadsheet Compare. The interface is a bit 1990s but on the other hand – it’s better than doing it manually.
If you want to experiment with it – create two Excel spreadsheets with different versions of a sentence, save it under two different names, close the files and then open a new file in Excel and after that – as my son would say – follow the destructions 🙂
