Simple Data Summation Workflow in n8n

This n8n workflow automates the process of summing a set of predefined monetary values and can be triggered manually. It is designed to process mock data for testing or demonstration purposes, showing how multiple inputs can be aggregated into a total sum. The workflow starts with a manual trigger, proceeds to generate mock data representing different USD amounts, and then calculates the total sum of these amounts using a custom function node. This approach is useful in scenarios where quick data aggregation is needed without relying on external data sources. It provides a clear example of data manipulation, aggregation, and the power of n8n’s function nodes for custom logic.
