If you receive a Microsoft Word document from someone who seems to think that everyone has Word, it can be frustrating. But you have several options to view and even edit the Word document on your Mac without buying anything. You can use Quick Look or Preview to view the file. TextEdit can be used to get access to simple text documents. Pages can open Word documents and most formatting is retained. You can also edit and export back out in Word format. The ultimate solution is to spend the money to get Word from the App Store, though it requires a paid subscription.
