Give DeepSeek Harness a real office environment. Univer Office Plugin brings spreadsheets, docs, slides, canvases, relational tables, and more into one runtime — with connected data, validation, versioned changes, and isolated worktrees for multi-agent collaboration.

What it solves

It provides AI agents with a fully functional office environment, allowing them to create, edit, and manage complex documents like spreadsheets, presentations, and rich-text docs through natural language. It solves the problem of agents being limited to plain text by giving them a runtime to handle structured office data and professional file formats.

How it works

The plugin integrates with DeepSeek Harness (DSH), enabling an agent to operate on a .univer file containing various content types. When a user makes a request, the agent creates an isolated draft (worktree) to perform edits. The user can follow these changes in a live preview window and must explicitly approve or discard the draft before it is merged into the main version. The system supports importing and exporting standard formats like .xlsx, .docx, and .pptx.

Who it’s for

Users of DeepSeek Harness who need AI agents to automate the creation of professional reports, data analysis spreadsheets, slide decks, and relational tables.

Highlights

  • Multi-format support: Handles spreadsheets, documents, slides, relational bases, and editable canvases within a single file.
  • Safe editing: Uses isolated worktrees and semantic side-by-side comparison to prevent agents from accidentally overwriting data.
  • Office interoperability: Imports and exports files to and from Microsoft Office formats (Excel, Word, PowerPoint).
  • Live verification: Provides real-time previews, screenshots, and PDF printing for the user to review agent work before approval.
