DSH × Univer Office

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.

English · 简体中文

dsh-univer-office is the Univer office plugin for DeepSeek Harness (DSH). Tell the agent what you need and it can create or edit spreadsheets, documents, presentations, multidimensional tables, and canvases, or work with existing Excel, Word, and PowerPoint files. Every change is verified and stays in the conversation for you to preview, approve, or discard.

After installation, describe the result you want in natural language. The agent handles creation, editing, and verification while you follow the work live and review the result in the conversation. Deliver spreadsheets as Excel (.xlsx), documents as Word (.docx), and presentations as PowerPoint (.pptx) files when needed.

See it in action

The agent created this spreadsheet from a natural-language request, then added conditional formatting and a chart in the same conversation. The result can be previewed, revised, merged into the current version, or discarded in place.

Deliver a standard Excel file: after review, ask the agent to export the spreadsheet as .xlsx so it can be opened and edited in Excel, WPS Office, and other compatible office applications.

1. Describe the task in natural language

2. Follow the result live while the agent works

3. Approve or discard the changes in the conversation

Generate a presentation from one request

Give the agent a topic, audience, page count, content outline, and visual direction. It can build the complete presentation, verify content and layout page by page, and leave the result in the conversation for review.

Deliver a standard PowerPoint file: after review, ask the agent to export the presentation as .pptx so it can be presented and edited in PowerPoint, WPS Office, and other compatible office applications.

2. Follow and verify the pages while the agent works

What can it do?

• Analyze and build spreadsheets — read or create Excel data, clean fields, write formulas, apply formatting and validation, create tables, charts, pivots, filters, sparklines, conditional formatting, and images, then export the result as .xlsx, .csv, or .tsv.
• Write and lay out documents — create paragraphs, rich text, lists, tasks, tables, images, charts, headers, footers, pagination, and page layouts.
• Create and revise presentations — generate a deck from an outline, redesign selected pages, edit text, shapes, images, tables, charts, and transitions, then detect off-page, overflowing, and overlapping text.
• Build lightweight databases — create Base tables, fields, records, and views with formula fields, filters, sorting, grouping, and Sheet-backed references.
• Draw editable canvases — create shapes, text, connectors, images, native charts, and diagrams, with connector and layout analysis.
• Compose several content types — one .univer file can contain Sheets, Docs, Slides, Bases, and Boards. Formulas and embedded content can reference other content in the same file.
• Work with Office files — import .xlsx, .csv, .tsv, .docx, and .pptx, then export the edited content in the matching format.
• Review agent changes safely — every write starts in an isolated draft. Watch changes live, then approve or discard them instead of letting the agent overwrite the current version.

Example requests

Create a simple payroll spreadsheet with employee, base salary, bonus, deduction, gross pay, and net pay columns. Calculate the totals automatically.

Create a six-slide lesson deck about bubble sort. Explain the concept, each comparison pass, pseudocode, and complexity, and check every page for layout problems.

Create a formal weekly project report with an executive summary, this week's progress, a risk table, next week's plan, headers, and footers, then export it as docx.

Create a customer-tracking Base with company, contact, stage, expected value, and next action fields, plus a view grouped by stage.

Create a sales Sheet and a summary Slide in the same .univer file, with the Slide chart reading the Sheet data.

Capabilities

Every content type supports isolated draft editing, review, revision, approval, and discarding. Base and Board support structural verification; Board file export is not yet supported.

Get started in 3 minutes

1. Install the plugin

If DSH is running, first press Ctrl+C in the terminal that started it. You can run the installation command while DSH is running, but the current DSH process will not load the new plugin automatically.

Install the plugin from npm:

dsh plugin --profile web add dsh-univer-office

Restart DSH after installation:

dsh web

After DSH starts successfully, refresh the existing DeepSeek Harness browser page with Cmd+R / Ctrl+R.

2. Describe what you need

Create a monthly expense spreadsheet with dates, categories, amounts, a total, and a few rows of sample data.

3. Review it in the conversation

• Changes appear in a live, movable preview window while the agent works.
• Review cards remain in the conversation and can be folded or opened fullscreen later.
• Continue editing, approve, or discard changes from the Univer page embedded in the card.

How it works

1. Describe the result you want and provide any source files.
2. The agent creates an isolated draft and edits the Univer content there.
3. Follow the live preview and ask for revisions until the result is ready.
4. Approve the result to update the current version, or discard the draft without changing it.

Approval and discarding always require an explicit user request.

Built-in tools

DSH selects these tools automatically; you normally do not need to call them manually.

Preview and review experience

• Live Univer window — changes open automatically in a window you can drag, resize, fold, or maximize.
• Conversation review cards — each edited .univer file has its own full preview card, while deleted temporary files leave no stale cards behind.
• Historical review — drafts, submitted changes, approvals, and discarded results remain in the conversation, with older cards collapsed by default.
• Session isolation — each DSH session shows only its own windows, cards, and review state.
• English and Chinese UI — the plugin shell and every open Viewer follow the DSH locale.
• Import, export, and print — the current version can import Office files, export supported content, and print from the Univer Ribbon. Draft and review previews do not allow import or export; Board provides print only.
• Sheet version history — the current version shows time-grouped history in the Ribbon. Read-only views can inspect versions, while editable views can restore one explicitly.

Requirements and current limits

• DeepSeek Harness and Node.js >=22.19.0.
• Some Slide layout checks and SVG text measurement require a local Chrome/Chromium executable. Set UNIVER_RENDER_BROWSER to use a specific browser path.
• Slide master pages, layout pages, and speaker notes are outside the current editing scope.
• Board mind maps, tables, ink, advanced editing, and file export are not yet supported.

Configuration

The defaults are designed for local use: the service starts at port 9080. If that port is occupied, it tries 9081, then continues upward one port at a time. Set these plugin options when you need different values:

Uninstall

dsh plugin --profile web remove dsh-univer-office
