Master data transformation with the complete set node guide

n8n Set Node Tutorial - Complete Guide

🎯 How It Works

This tutorial workflow teaches you everything about n8n's Set node through hands-on examples. The Set node is one of the most powerful tools in n8n - it allows you to create, modify, and transform data as it flows through your workflow.

What makes this tutorial special: - Progressive Learning: Starts simple, builds to complex concepts - Interactive Examples: Real working nodes you can modify and test - Visual Guidance: Sticky notes explain every concept - Branching Logic: Shows how Set nodes work in different workflow paths - Real Data: Uses practical examples you'll encounter in automation

The workflow demonstrates 6 core concepts: 1. Basic data types (strings, numbers, booleans) 2. Expression syntax with {{ }} and $json references 3. Complex data structures (objects and arrays) 4. "Keep Only Set" option for clean outputs 5. Conditional data setting with branching logic 6. Data transformation and aggregation techniques
