And for many people, Excel is the gold standard program for crunching large amounts of data. That's because Word, Excel and PowerPoint are packed with advanced features, like mail merge, detailed charts and animated slides that are missing or limited with other programs. Microsoft Office has long been the standard for those who use word processors, spreadsheet tools and presentation builders at work. It's essentially a bookmark for your documents, and it's a fantastic tool for anyone working on a lengthy project over several days or weeks.
