Learn JS Data Processing in n8n Code Node: Filter, Analyze, Export

This workflow is a comprehensive educational template that demonstrates practical JavaScript usage within n8n's Code node. It processes sample employee data through real-world scenarios like filtering adults, calculating bonuses, generating team statistics (averages, role distributions, KPIs), and formatting for exports (CSV, emails, APIs). Perfect for n8n beginners and developers learning data manipulation patterns.

The workflow starts with a Manual Trigger followed by Set Sample Data node providing realistic business data. Three specialized Code nodes then showcase: 1) Filter & Transform for cleaned adult lists with bonuses; 2) Calculate Stats for analytics reports; 3) Format for Export preparing API-ready payloads. It emphasizes n8n best practices like proper JSON handling, array methods (filter, map, reduce), and return formats.

Benefits include rapid skill-building for Code node mastery, reusable patterns for client projects, and time-saving automation foundations. Ideal for team training, onboarding, or demos highlighting n8n's data processing power.

Use cases: Adapt for form data processing, CRM analytics, HR reporting, or any JSON transformation needs. Transform into custom workflows for business automation, e-commerce data prep, or survey analysis.
