Automated Expense Tracking with AI and Google Sheets

This n8n workflow streamlines the process of tracking expenses via chat messages, leveraging AI to parse natural language inputs and automatically log them into Google Sheets. The workflow starts with a webhook trigger where users send expense details through chat. An AI agent then processes these inputs, extracting key expense data such as amount, description, and date. The parsed data is formatted into JSON and sent to a dedicated sub-workflow, which further processes and saves the expense information into Google Sheets, creating a structured expense log. Additionally, the workflow incorporates OpenAI’s language models for natural language understanding and information extraction, ensuring versatile input handling. This automation is perfect for personal finance management, business expense logging, or any scenario requiring fast, hands-free expense recording through conversational interfaces.
