Automated Document Processing & AI Analysis Workflow

This n8n workflow automates the extraction and analysis of data from various document formats, including PDFs, XLS, and CSV files. It begins with a local file trigger, monitoring a directory for new files. Once a file is detected, the workflow reads the file content, extracts relevant data based on its type, and processes it through AI-powered language models (Ollama and LangChain agents). The system dynamically routes data depending on its format, enabling targeted analysis or transformation. Finally, the processed data is saved back to the disk. This workflow is ideal for automating repetitive data extraction, analysis, and reporting tasks for businesses managing large volumes of documents.
