Automated Personal Expense Tracking with Daily Summaries

This n8n workflow automates personal expense management by providing a seamless system to input, validate, and store expenses via a webhook API. When an expense is submitted, the workflow validates and formats the data, then appends it to a Google Sheets spreadsheet for persistent storage. Additionally, the workflow includes a scheduled daily process that reads the day’s expenses, calculates total spending and category breakdowns, and generates a summary report. The system also responds instantly to API calls with success or error messages, making it suitable for mobile apps, websites, or direct API integrations. This setup simplifies expense tracking, enabling users to monitor their finances and review daily spending habits effortlessly, all automated within a reliable, cloud-based environment.
