A specialized data extraction tool built for developers, data scientists, and ML engineers. Instead of a flat text dump, this utility parses the PDF binary stream and exports every text segment as a structured JSON object. It includes the exact physical location (X,Y coordinates), width, height, and font dictionary properties. This is the ideal tool for training layout-aware OCR models or building precise automated data scrapers without uploading sensitive datasets to a cloud server.
