If you’re familiar with the desktop version of Word, you might know it offers a few different ways to automatically insert text. Those options don’t yet exist in Word Online.
If you have Word for the desktop, click Edit Document > Edit in Word or click Open in Word to open your document.
Then follow the instructions in Automatically insert text.
When you save the document and reopen it in Word Online, you’ll see the changes you made.
Tip: Word Online works seamlessly with Word and other Office desktop programs, and we update it based on input like yours. For the latest feature announcements, visit the Office Web Apps blog.
