D: Are you tired of juggling messy data across multiple workflows? 🤯 The n8n Aggregation Node is your secret weapon to streamline, analyze, and transform complex datasets effortlessly! In this guide, we’ll dive deep into 10 powerful ways to leverage this node like a pro—complete with real-world examples and emoji-powered explanations! 💡

🔍 What is the Aggregation Node?

The Aggregation Node in n8n helps you combine, summarize, and process multiple data inputs into a structured output. Think of it as your data wizard 🧙‍♂️ that can:

• Merge data from different sources
• Calculate averages, sums, counts
• Filter & group data dynamically
• Transform raw data into actionable insights

🎯 10 Killer Use Cases (+ Examples!)

1️⃣ Merge API Responses into One Dataset

Got data from 3 different APIs? Use the Aggregation Node to combine them into a single output!

// Input: Two separate API responses  
API 1: [{ "id": 1, "name": "Alice" }]  
API 2: [{ "id": 1, "age": 30 }]  

// Aggregation Rule: Join by "id"  
Output: [{ "id": 1, "name": "Alice", "age": 30 }] ✅  

2️⃣ Calculate Real-Time Sales Metrics

Need total revenue, average order value, or top-selling items? Aggregate sales data on the fly!

📌 Example:

• Operation: Sum
• Field: order_amount
• Output: Total Revenue: $5,200 💰

3️⃣ Group Customer Feedback by Sentiment

Automatically categorize support tickets as Positive, Neutral, or Negative using NLP + Aggregation!

"Group By": "sentiment_score",  
"Operations": [ { "type": "count", "field": "ticket_id" } ]  

// Output:  
{ "Positive": 42, "Neutral": 15, "Negative": 8 } 📊  

4️⃣ Deduplicate CRM Contacts

Merge duplicate entries from spreadsheets, forms, and CRM exports.

🔧 How?

• Group By: email
• Operation: Keep First (or Merge Fields)

5️⃣ Build Dynamic Reports from Database Queries

Combine PostgreSQL + Google Sheets data into a single executive dashboard!

📌 Pro Tip: Use Aggregate → JSON to Text → Email/Slack Alert!

🚀 Pro Tips for Advanced Users

• Chaining Nodes: Pair with Function Node for custom logic.
• Error Handling: Use IF Node to filter null values before aggregating.
• Webhooks: Trigger aggregations in real-time (e.g., new form submission → update report).
