Built an n8n workflow to extract and validate financial data from PDFs using structured logic, error handling, and reliable downstream delivery.
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.
