Paper Instruments releases Paper Office, a Python suite for agents to safely edit Word, PowerPoint, and Excel files

Paper Office is a suite of Python packages that wrap python-docx, python-pptx, and OpenPyxl with safety checks and broader editing capabilities. Across 5 models and 61 tasks, Paper packages plus guidance passed 92.5% of trials, vs 80.7% for the upstream packages alone and 69.5% for Anthropic's Office skills. Agents resorted to raw OOXML editing in only 1.6% of Paper runs, compared to 78.7% without skills and 50.5% with Anthropic skills. The team argues that low agent adoption in consulting, law, and banking stems from tools that silently corrupt formatting, break references, or produce client-unready output. Paper Office keeps the familiar imports and adds cross-run text search, native Word redlines, comment threads, content controls, cross-document composition, and package-level diff saves, refusing unsafe operations instead of quietly breaking files.
