Logic-Driven Financial PDF Extraction with Error Handling (n8n)
Hassan Nawaz
Built a production-ready PDF extraction workflow in n8n to process complex financial documents using deterministic logic and controlled AI assistance. The system ingests PDFs, applies structured parsing rules, validates outputs, and extracts normalized data based on predefined business logic.
The workflow includes branching, error detection, retries, and fallback paths to handle inconsistent formats and partial failures. Extracted data is written to downstream systems such as Google Sheets, ensuring reliable results under real-world document variability.
