Learn n8n Logic: Merge, IF & Switch Tutorial

This workflow serves as an interactive tutorial demonstrating the core logic nodes in n8n: Merge, IF, and Switch. It simulates a package sorting center where Set nodes create three packages (two letters and one parcel). The first Merge node combines them into a single stream, mimicking multiple conveyor belts joining. An IF node then sorts by fragility, splitting into true/false paths for separate processing before a second Merge recombines them—a key 'Split > Process > Merge' pattern.

Next, a Switch node performs advanced routing based on destination (London, New York, Tokyo, or default), showcasing multi-output logic. This step-by-step journey builds a solid foundation for controlling data flow in complex automations.

Benefits include rapid comprehension of branching logic, avoiding common pitfalls like data loss in merges, and enabling scalable workflows. Ideal for beginners and intermediate users transitioning to production-grade automations.

Use cases: Educational onboarding for teams, prototyping conditional logic for CRM data routing, API response handling, or any scenario needing dynamic decision-making. Zero setup time—fully self-contained and ready to import.
