No, but it's far easier to see what the hell an R script is doing versus an Excel file. And there's just a ton more that R can do that Excel can't. More powerful plotting options, more tools like Random Forests or mixed effect models. And has less issues with floating point. Excel is good for accounting tasks because that's what it and other spreadsheet software were originally designed for. Data science tasks are tacked on.
