If you are spending five hours of overtime every week stuffing hundreds of PDF, PPT, and Excel files into your RAG system, the root cause is fragmented parsing libraries. The existing structure of mixing PyPDF2 and openpyxl only increases code complexity. Adopting Microsoft's MarkItDown can eliminate complex branching logic.
When refactoring the pipeline, use the Processor Factory pattern:
This structure allows for independent scaling of the parsing engine. Preserving table structures reduces table retention errors by 34% when LLMs read documents (based on Microsoft 2024 announcement).
Embedding token costs are directly proportional to the length of the Markdown file. Results extracted by MarkItDown often contain metadata or noise that doesn't necessarily need to be sent to the LLM. Filtering this out alone can reduce API costs by 30%.
Build an efficient filtering logic:
Optimizing token efficiency can noticeably lower monthly enterprise API costs.
When library versions change, parsing results also shift slightly. Stop having engineers manually open and verify files one by one. Introducing snapshot testing allows you to catch quality degradation immediately.
Create a unit test environment to prevent regressions:
This automation framework eliminates the manual cross-checking tasks that used to eat up five hours every week.
Processing thousands of documents sequentially is a waste of system resources. By using concurrent.futures.ProcessPoolExecutor to parallelize batch processing, you can finish tasks that used to take days in just a few hours.
Implement the parallelization architecture as follows:
This approach helps maintain data freshness while using system resources efficiently.
