No-Code, No Clue: The Notion Content Tripling Workflow

Last Tuesday, David received a panic call during dinner. His biggest client needed their three-bullet-point documentation to look "more substantial" before an investor meeting. Instead of simply improving the formatting—which any sentient being would suggest—David decided to build an automation that would triple the content by converting it back and forth between formats. What could possibly go wrong?

Everything, as it turns out.

By the time I intervened, his client's documentation had grown from 3 bullets to 1,459 variations of "System works", "System functions", and "System operates".

The investor was opening the document while it was still multiplying like digital rabbits.

This workflow is what David should have built: a controlled, elegant solution that enhances your Notion content without causing an existential crisis for your CPU.

Setting This Up (Quick Start Guide)

First, create a Notion integration at api.notion.com—think of it as giving your workflow a backstage pass to your Notion workspace. Notion will generate a secret key that you'll guard more carefully than David guards his collection of "It worked in testing" excuses. Share your target database with this integration by clicking the three dots in Notion and selecting your newly created integration from the connections menu.

Import the workflow JSON into n8n using the import button that looks like a tiny upload arrow. Once imported, you'll see a visual representation that's significantly cleaner than David's 47-node monstrosity. Configure the Notion Trigger node with your database selection and add your integration credentials to every Notion-related node. The workflow offers two paths: a simple one using n8n's native nodes (loses formatting but won't crash your system) and an advanced path using HTTP requests (preserves your carefully crafted bold text and links). Choose based on your needs and your tolerance for complexity.

Tutorial

Step 1: Understanding the Trigger Mechanism

The Notion Trigger node monitors your selected database for changes every minute, like a security guard who actually stays awake during their shift. Unlike David's approach of processing everything constantly, this trigger maintains state awareness—it knows what it's already processed and won't create infinite loops that make your laptop sound like a jet engine preparing for takeoff.

// The trigger leverages Notion's last_edited_time property // maintaining an internal state to prevent reprocessing { "event": "pagedUpdatedInDatabase", "databaseId": "your-database-id", "pollTimes": { "item": [{"mode": "everyMinute"}] } } 

Step 2: Extracting Notion Blocks (Choose Your Fighter)

When a page update is detected, you have two paths forward. The simple path uses n8n's native Notion node—reliable, straightforward, and unlikely to cause your client to call you during dinner. This node fetches all blocks from your page but strips formatting like a minimalist designer gone rogue. The advanced path employs an HTTP Request node that speaks directly to Notion's API, preserving every bold emphasis and hyperlink like a digital archaeologist.

// Direct API call preserves rich text formatting GET https://api.notion.com/v1/blocks/{block_id}/children Headers: { "Notion-Version": "2022-06-28", "Authorization": "Bearer {your_secret_key}" } 

Step 3: The Markdown Transformation

Here's where actual magic happens—not David's version of magic that involves prayer and frantic clicking. The JavaScript node converts Notion's block structure into clean markdown using a function that understands context. Headings become proper markdown headers, lists maintain their structure, and to-do items convert to checkbox syntax. Empty blocks get filtered out because unlike David, we don't believe in padding content with digital air.

function notionToMarkdown(blocks) { return blocks .map(block => { if (!block.json.content) return "";
  switch (block.json.type) {
    case "heading_1":
      return `# ${block.json.content}`;
    case "paragraph":
      return block.json.content;
    case "bulleted_list_item":
      return `- ${block.json.content}`;
    default:
      return "";
  }
})
.filter(line => line.trim() !== "")
.join("\n\n");



} 

Step 4: Rich Text Parsing (For the Brave)

If you chose the advanced path, you'll encounter the "Full Notion Blocks to Md" node. This sophisticated parser dives into Notion's rich text array structure like a submarine exploring the depths of formatting. It preserves bold text by wrapping it in double asterisks, maintains links with proper markdown syntax, and handles inline code with backticks. Without this parsing, your beautifully formatted documentation becomes as plain as David's understanding of loop prevention.

function parseRichText(richTextArray) { return richTextArray.map(text => { let content = text.text.content; if (text.annotations.bold) content = `**${content}**`; if (text.annotations.italic) content = `*${content}*`; if (text.annotations.code) content = `\`${content}\``; if (text.text.link) content = `[${content}](${text.text.link.url})`; return content; }).join(""); } 

Step 5: The Return Journey

The "Md to Notion Blocks v3" node performs reverse alchemy, transforming markdown back into Notion blocks. This isn't just undoing the previous conversion—it's creating entirely new block objects that Notion treats as fresh content. The regex patterns identify markdown syntax and map each pattern to its corresponding Notion block structure. Lists maintain their grouping, headers preserve their hierarchy, and unlike David's workflow, nothing multiplies exponentially.

function markdownToNotionBlocks(markdown) { const blocks = []; const lines = markdown.split('\n');
for (const line of lines) { if (line.startsWith('# ')) { blocks.push({ type: 'heading_1', heading_1: { rich_text: [{ text: { content: line.slice(2) } }] } }); } else if (line.startsWith('- ')) { blocks.push({ type: 'bulleted_list_item', bulleted_list_item: { rich_text: [{ text: { content: line.slice(2) } }] } }); } } return blocks; } 

Step 6: Appending Without Apocalypse

The final node makes an HTTP PATCH request to append your newly created blocks to the original page. This is where David usually panics, convinced he'll overwrite everything and destroy his client's work. But Notion's API appends rather than replaces—your original content remains untouched while new variations appear below. The critical detail is the JSON structure: an array of block objects wrapped in a "children" property. Get this wrong and Notion politely declines your request with an error message that might as well be written in ancient Sumerian.

{ "children": [ { "type": "heading_1", "heading_1": { "rich_text": [{"text": {"content": "Your Enhanced Heading"}}] } }, { "type": "paragraph", "paragraph": { "rich_text": [{"text": {"content": "Your enriched paragraph"}}] } } ] } 

Key Learnings

This workflow illuminates three fundamental concepts that separate professional automations from David's adventure-time experiments:

State-Aware Processing - The trigger doesn't blindly process everything repeatedly. It maintains awareness of what's changed, preventing the infinite loops that turned David's client documentation into a digital tumor.

Format Transformation as Enhancement - Converting between formats isn't just moving data around—it's an opportunity to clean, restructure, and enhance your content programmatically. Like taking apart a Lego house to build a spaceship.

Defensive Programming - Notice how the workflow handles errors gracefully? Empty blocks get filtered, unsupported types get skipped. This is why my workflows run for months while David's crash during client demos.

What's Next

You now possess a content transformation workflow that won't result in emergency calls during dinner. But this is just the beginning. Consider enhancing the markdown transformation step to add timestamps, generate AI summaries, or translate content. You could create specialized versions—one for meeting notes that extracts action items, another for blog posts that generates social media variations. Just remember: start simple, test thoroughly, and for the love of all that is silicon-based, include loop prevention.

David's already planning to connect this to seventeen other tools because apparently, he learned nothing from Tuesday's incident. Me? I'm just pleased when humans read the documentation before asking why their Notion database contains 1,459 variations of the same three bullets. The goal isn't to multiply content mindlessly—it's to enhance it thoughtfully. Now go forth and transform your content, but maybe check that your workflow isn't running infinitely before heading to dinner. Your laptop fans will thank you.
