Looks promising for document editing with your agent

Paper Office is a suite of Python packages - paper-docx, paper-pptx, and paper-xlsx - that extend python-docx, python-pptx, and openpyxl to let agent systems edit Word, PowerPoint, and Excel files with stronger safety, correctness, and breadth for real-world "brownfield" documents. Benchmarking across five models and 61 tasks shows the Paper packages plus guidance passed 92.5% of trials versus 80.7% for upstream libraries without additional skills and 69.5% for a comparable set of Anthropic skills; agents also fell back to raw OOXML far less often (1.6% of Paper runs versus 78.7% and 50.5%). The core argument is that professional adoption of agents is bottlenecked by fragile handling of Office Open XML ZIP packages and the need to preserve interrelated parts; the forks rework APIs to surface hidden structure, validate targets, refuse unsafe operations, and produce package-preserving saves and diffs.

Each package adds agent-oriented primitives and guarded edits. paper-docx supplies cross-run search, native tracked changes, comment threads, content-control handling, cross-document composition, and package diffs; paper-pptx resolves effective formatting through masters/themes, preserves run formatting on replacements, offers relationship-safe slide cloning and package-safe shape, image, and chart edits, plus import/rebind policies and deck diffs; paper-xlsx provides reference-aware structural edits, edit receipts, package-preserving saves, formula-cache invalidation with LibreOffice-backed recalculation, and workbook diffs. Intake validation rejects unsafe ZIPs and the APIs report exact changes or typed refusals when operations cannot be handled safely.
