n8n Workflow for Data Filtering, Analysis, and Export

This n8n workflow showcases how to utilize Code nodes for practical data manipulation tasks, making it ideal for users seeking to automate data filtering, statistical analysis, and data formatting for external systems. The workflow starts with a manual trigger, where sample user data is set, then processes the data through three main Code nodes. The first Code node filters users over 18, adds a bonus calculation, and formats email addresses. The second Code node aggregates data to generate key statistics, such as averages and totals. The third Code node formats data into various export-ready formats, including CSV, email lists, and API payloads. These processes illustrate real-world applications like lead qualification, KPI reporting, and data export for marketing or integrations. The workflow is especially useful for teams managing employee or customer data, providing a flexible template for common data processing needs.
