This n8n workflow integrates OpenAI’s language models with Excel data for dynamic analysis and conversational AI. It starts with a webhook trigger to initiate a chat conversation, then uses a smart AI agent that interacts with an Excel dataset to answer queries. The workflow leverages LangChain nodes for chat and memory management, enabling users to ask complex questions about their data and receive real-time, AI-driven responses. Practical uses include data analysis, customer support, or internal reporting by querying Excel files through natural language interactions.
