Once you have your draft completed, you can choose to edit in Notion or edit in a different text editor. Below is the steps, I would take to export my draft from Notion.
- First, duplicate the appropriate First Draft page.
- Remove any additional buttons and callouts from the duplicated page.
- Export the page as HTML.
- Unzip the HTML.
- In Microsoft Word, go to the insert tab and click Text from file. (Shown in the image below)

- Select the HTML file that you unzipped.
- It should import all your information correctly.
- You can now edit it your draft.
