Measured write-ups on what happens to Office files when Python code and AI agents edit them.
Wolf, BetterOffice, office2pdf and LibreOffice against Microsoft Office's own PDFs
We rendered the same DOCX, PPTX and XLSX files with Wolf, BetterOffice, office2pdf and LibreOffice and compared every page with the PDF Microsoft Office exports, on a held-out corpus and on the corpora we develop against.
Wolf Runtime by WolfSDK: edit Office files and see what changed
Wolf Runtime edits and renders XLSX, DOCX, PPTX and PDF files through one command-line contract. We measured untouched package parts, receipts, rendering against Office output, image footprint and sandbox behavior.
What a one-cell agent edit removed from 4 of 8 Excel workbooks
A one-cell edit through the openpyxl and LibreOffice recipe of a published xlsx agent skill removed slicers, a timeline, sparklines, or a Power Pivot data model from 4 of 8 workbooks, and the recalculation reported success every time.
Teaching agents to update the Office files a business already uses

What happens when an AI agent edits a spreadsheet? Inside headless LibreOffice's silent OOXML rewrites
We diffed raw OOXML packages and benchmarked performance when AI agents use headless LibreOffice versus a dedicated spreadsheet engine.
