GenOffice

About

Real Word, Excel and PowerPoint files, edited by you or your agent

GenOffice opens and saves native Office formats and only rewrites what changes, so files keep working in Word, Excel and PowerPoint. Inside the app, AI edits land as tracked changes or diffs you can roll back, spreadsheets get live formulas instead of pasted numbers, and decks are drafted onto an editable canvas. PDF to Word, Excel or PowerPoint conversion runs on your machine. The part that matters for agents: genoffice mcp starts a stdio MCP server with 29 tools (create_docx, create_xlsx, create_pptx, docs_read and docs_apply, sheet and slides tools, render, convert) plus a staged deck flow that checks every slide before it builds the .pptx and hands back a PNG per slide for the model to look at. There is also an agent skill (npx skills add genspark-ai/genoffice) and an optional HTTP server for remote boxes. You can sign in with Genspark or bring your own key for Claude, OpenAI, Gemini, Grok, OpenRouter or a local OpenAI-compatible server. About 10k GitHub stars.
