Depends on what you're planning to do with the spreadsheet. If it's display only, it's easy to bundle into a PDF or Word doc. If you need to interact with it, sure, standalone is better. But this the first case is something I deal with all the time. If I'm looking at financial statements for a board meeting, I really don't need a live spreadsheet, and it's massively more convenient to have it bundled in with the agenda, minutes, reports, etc.
