  3. File extension *.docx

    Hi Randy,

    To change the file extension when saving a document in Word 2013, you may follow the steps below:

    • Click on File; then, select Options from the list.
    • In the Word Options window, choose Save.
    • Under Save files in this format, select *.doc from the list.
    • Hit OK button to confirm and save the changes.

    If ever your Word 2013 application is not recognizing the changes you have made, you may restart the application; however, if the issue still persists, we suggest that you repair it. To do this, see this

    We would appreciate it if you could get back to us and provide us your feedback.
