Is there a quick, free viewer for Word docs?

Try Bean.

The last time I tried it, it was pretty quick (quicker than OpenOffice) and according to the website, can open .docx files.

Here's an interesting solution I've never seen before. Apparently a .docx is just an .xml file (which I've heard, but never actually investigated lol).

• Change the .docx extension to .zip
• Unzip the file. You'll get an .xml
• Open and read the resulting .xml

Preview.app and TextEdit.app can both open .doc(x) files. While they may not handle intricate formatting, I have found they will do a decent job with 99% of the Word files that I receive.

For more advanced documents, Pages remains the best answer, and it's now free for effectively everyone.

Pages by Apple can be used to view Word document files. Pages is available as macOS and iOS native app as well as for Web.

Pages used to be a paid app, but is now available free of cost. Pages Web app can be used on compatible Web browsers even on a Windows PC.
