What Is Custom Data Extraction?
Custom data extraction is the automated harvesting, structuring, and enrichment of fragmented public information scattered across websites, PDF documents, enterprise portals, and application endpoints. By deploying resilient browser clusters and OCR engines, we transform unstructured web text and tables into validated, normalized database records ready for machine learning, price intelligence, and competitive benchmarking.
