If you’ve created a document in the Word desktop client, Word Online will preserve everything you’ve done, including the spacing between bullets and text in your lists. Unfortunately, while you can change the spacing between items in a list, you can’t change the space between your bullets and the item text in Word Online.
If you already own the desktop version of Word, you can use it to change the spacing between the bullets and the text in your list. If not, you can try or buy the latest version of Office now.
We make frequent updates to Word Online. To get the latest feature announcements, visit the Office Online blog.
