Learn JSON Basics: Interactive n8n Tutorial for Beginners

This workflow serves as a beginner-friendly, interactive tutorial on JSON basics within n8n. It guides users through essential concepts step-by-step via simple nodes: starting with key/value pairs, then covering core data types (strings, numbers, booleans, null, arrays, objects), dynamic expressions using {{ }}, and a final exam that combines everything into a complete JSON object. Each node includes sticky notes with clear explanations and execution outputs for immediate understanding.

The benefits are immense for n8n newcomers: it demystifies JSON—the backbone of data in automations—in under 10 minutes without any prior knowledge or setup. Users gain confidence in handling data structures, referencing previous node outputs, and building complex payloads, accelerating workflow creation.

Ideal use cases include onboarding new team members to n8n, self-paced learning for developers transitioning to no-code automation, or quick refreshers for anyone struggling with expressions. Execute once and master JSON for real-world integrations like APIs, CRMs, or data transformations.
