Honest breakdown of what transfers and what doesn't.
Headings H1–H6
Full supportAll six heading levels render with blue color and varying sizes. OneNote maps them to built-in heading styles natively, better than Google Docs.
Bold, italic & strikethrough
Full supportBold, italic, bold+italic, and strikethrough all render correctly. Strikethrough works here unlike Google Docs.
Tables with formatting

Links
Full supportAll link types including email mailto render as blue underlined clickable text.
