n8n Workflow for Data Merging and Enrichment

This n8n workflow automates data merging and enrichment processes, useful in scenarios like inventory management, recipe adjustments, and data analysis. It begins with a manual trigger, allowing users to initiate the process. The workflow includes note nodes for explanations, with core nodes focused on merging datasets, similar to SQL joins. In the example, it compares ingredients needed for a recipe with ingredients in stock, using different join types like left join (to add quantities), inner join (to filter in-stock ingredients), and union (to combine datasets). These operations demonstrate how n8n can efficiently handle complex data merging tasks. The workflow supports practical applications such as updating inventory, customizing recipes based on stock levels, or combining data from different sources for enhanced insights.
