Univer ships Office Harness, one runtime to make spreadsheets and docs native to AI agents

Univer, the open-source Office engine (30k+ GitHub stars across Univer and Luckysheet), shipped Office Harness to make Office work native to AI agents. The pitch: reasoning is getting solved faster than execution — hand an agent a spreadsheet, doc, and deck, and too much of the job is still parsing formats, moving data between files, and rebuilding context. Univer unifies spreadsheets, docs, slides, canvases, and relational tables into one runtime; Office Harness adds connected data, validation, isolated worktrees, and human review. The Office SDK is the foundation, with CLI, plugins, and Workspace built on top.
