upvoted_answer: To convert a .docx file to another format, you should download a program called Calibre
  
  
  First you must add the .docx file to your Calibre library
  
  Then you need to select the book, and click on Convert books
  
  Select your output format (for Amazon Kindle, select AZW3), and click OK. After it has completed, the newly converted ebook will appear in your Calibre library folder
