To turn lines of text into a numbered list, select the list and, on the Home tab, in the Paragraph group, click Numbering. Each line or paragraph becomes a numbered item.
Starting with a blank page?
Place your cursor where you want a numbered list.
On the Home tab, in the Paragraph group, click the arrow next to Numbering.
Choose a number style and start typing.
Press Enter every time you want a new item, or press Enter twice to end the numbered list.
Tips: When you start a paragraph with an asterisk or a number 1., Word assumes you're beginning a bulleted or numbered list and displays the AutoCorrect Options button. If you don't want your text turned into a list, click the button and then click Stop Automatically Creating Numbered Lists.
