Newbie here looking to see if this would be something I would do inside Adobe XD or not. I am creating a website with data. Is it possible for this data to be converted into a PDF like Quickbooks does when creating an invoice?
Yes. Website sized artboards can be converted into PDF. You can create PDF for any of the artboard you have created. You've to select the artboard, File -> Export -> Selected/All artboards -> Select PDF format from dropdown.
