The quality of PDF parsing significantly impacts the performance of Retrieval-Augmented Generation (RAG) systems, often acting as a hidden bottleneck. Poor parsing can corrupt text chunks with encoding errors or flatten tables, leading to inaccurate or hallucinatory responses from LLMs. A custom pipeline using `pdfplumber` with specific post-processing rules for merged cells and in-cell newlines was developed to address these issues, demonstrating improved accuracy in reconstructing table structures for better RAG performance.
