Be warned, though, that these automated methods are not 100% reliable. After using them, you really do need to go through and check for errors manually. The tools are a good first step, but not a complete solution (not, at least, if you want to publish the book. Obviously if it's just for your personal use, you may not be concerned about a few mistakes.).

Tools tend to have problems with words with initial apostrophes, particularly in books where the single apostrophe is also used for speech marks.
