 Notion API Block Format 
 
 
The Notion API uses a block-based content model where each paragraph, heading, list item, and code block is a separate JSON object with a type, rich_text array, and optional properties. Converting from Markdown to this format manually is tedious — this tool automates the process, handling inline formatting (bold, italic, code, links) within rich_text arrays and mapping Markdown syntax to the correct Notion block types.
