If you’re familiar with the desktop version of Word, you might know you can use it to create fillable forms. That option isn’t available in Word Online.
To open your document in the desktop version of Word, click Edit Document > Edit in Word, or click Open in Word.
Then follow the instructions in Create a fillable form.
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.
