This document generation engine transforms raw experiment submissions and repository links into formatted PDF and DOCX student lab records. By decoupling submission data from the visual presentation layer, the tool eliminates repetitive manual table drawing and enables students to compile standardized laboratory records with verified verification codes and consistent institutional formatting. 1. Client-Side Link-to-QR Generation: Repository URLs and source links are converted directly in the browser into high-density 2D QR codes without intermediary server calls. Each generated code is embedded alongside the experiment metadata, providing instant verification of student work right from the printed or digital record. 2. Zero-Server In-Memory Processing: Eliminates backend document servers, external database dependencies, and file storage bottlenecks. The complete document assembly pipeline runs directly inside the client engine, generating and delivering print-ready PDFs and editable DOCX files on demand.
