If you're doing this sort of thing frequently, learn regular expressions. Yes, the barrier to entry can be a little high for an otherwise principally non-technical person, however if text manipulation is a frequent task of yours, you'll thank yourself for having learned.
Many editors (Notepad++, etc.) support regular expressions for search-and-replace. In this case you'd simply search for \s+ (any whitespace characters) and replace them with a single space. This will convert all sequences of newlines, tabs, and spaces, to a single space.

But, if you were to copy/paste a whole PDF textbook, you could run into problems.
