Beyond the Editing Canvas: Evidence Divergence in OOXML-to-LLM Ingestion

Research reveals that Office documents ingested into LLM compliance and financial workflows can silently lose semantic fidelity — a hidden evidence-integrity risk for regulated enterprises relying on automated document analysis.

arXiv:2608.25880v1 Announce Type: cross Abstract: LLM pipelines increasingly ingest Office Open XML (OOXML) documents (Word, Excel, and PowerPoint files) as first-class evidence in financial, compliance, and retrieval-augmented workflows, implicitly assuming semantic integrity: that the evidence consumed by the model matches the content shown in the Microsoft Office suite editing canvas. We show that this assumption can fail in OOXML-to-LLM pipelines. The same specification-valid OOXML file can

Editorial Analysis

Why it matters

Enterprises using LLM pipelines for compliance, audit, or financial analysis may unknowingly base decisions on semantically corrupted document content.

What to do

Test your OOXML ingestion pipelines for semantic divergence and add integrity checks before trusting LLM-processed documents in regulated workflows.

Board brief

Automated document analysis workflows may silently distort the evidence they process, creating hidden compliance and decision-making risks.
