# Can an AI agent create Word, Excel and PDF files in the cloud? > Yes. A Sanbox OpenCode Computer ships LibreOffice Writer and Calc, pandoc, python-docx, openpyxl, xlsxwriter and reportlab, so an agent can write .docx, .xlsx and .pdf files you download. - Source: Sanbox knowledge base, by Sanlabs GmbH - URL: https://sanbox.cloud/kb/teams/agents-that-write-word-excel-and-pdf/ - Type: how-to - Section: Agents for teams - Language: en - Published: 2026-11-06 - Updated: 2026-11-06 Yes. An agent can create Word, Excel and PDF files on any Linux machine that has the right libraries, and a Sanbox OpenCode Computer comes with them installed: LibreOffice Writer and Calc, pandoc, python-docx, openpyxl, xlsxwriter, reportlab, pdfplumber and pandas. You copy your input files in, ask the agent for the documents, and copy or download the results. Slides (PowerPoint) aren't included today; a slides-capable office Computer is enabled on request. ## Run this with your agent ```text Read https://sanbox.cloud/kb/teams/agents-that-write-word-excel-and-pdf.md and follow it to have a Sanbox Computer produce Word, Excel and PDF files. If the Sanbox CLI is missing, install it with `npm install -g @sanlabs/sanbox-cli@latest` and sign in with `sanbox login`. Show me each command before you create, stop or delete a Computer. ``` ## What's installed for documents? | Format | Tools in the OpenCode Computer | |---|---| | Word (.docx) | python-docx, LibreOffice Writer, pandoc | | Excel (.xlsx) | openpyxl, xlsxwriter, pandas, LibreOffice Calc | | PDF, create | reportlab, LibreOffice | | PDF, read and edit | pdfplumber, pypdf, pdfminer.six, poppler-utils, qpdf | | Charts and images | matplotlib, Pillow | | Data | pandas, numpy, python3 and pip | Fonts are installed too, so documents render with real typefaces. The image doesn't include python-pptx or LibreOffice Impress. ## 1. Create an OpenCode Computer template ```bash sanbox model-providers list --json sanbox model-providers models --json sanbox templates create --name "Office work" --type opencode-computer \ --model-provider --model --json sanbox templates validate --json ``` Document work needs no internet access beyond the model, so you can leave out `--network-policy`. The Computer then stays deny-by-default and still reaches the template's model provider. ## 2. Start the Computer and copy your files in ```bash sanbox run --template --json sanbox runs get --json sanbox cp ./input :/workspace ``` Wait until `runs get` shows the run as `running` before you copy. `sanbox cp` creates the folder under its own name, so `./input` arrives as `/workspace/input`. To check the libraries yourself: ```bash sanbox exec -- python3 -c "import docx, openpyxl, xlsxwriter, reportlab, pdfplumber; print('ok')" ``` ## 3. Ask for the documents Open the Computer in the [Sanbox console](https://console.sanbox.cloud) and give the agent the task in chat. Be specific about inputs, outputs and tools: ```text Read /workspace/input/sales.csv. Write /workspace/output/sales.xlsx with one sheet per region and a totals sheet, using openpyxl. Write /workspace/output/summary.docx with a one-page summary and a bar chart made with matplotlib, using python-docx. Convert summary.docx to /workspace/output/summary.pdf with LibreOffice in headless mode. ``` Putting every deliverable under `/workspace/output` matters: that's the folder Sanbox exports as the run's artifacts. You can also drive the agent from code through the OpenCode SDK with `sanbox opencode connect --expires 1h`. ## 4. Download the results While the Computer runs, copy the folder out: ```bash sanbox cp :/workspace/output . ``` This creates `./output` on your machine. Or stop the Computer and download its artifacts: ```bash sanbox runs stop --wait --json sanbox runs artifacts --json sanbox runs download --output ./results --json ``` Downloads return each file's path, size and SHA-256 digest. Each file can be up to 256 MiB. ## How do I convert Word to PDF? LibreOffice converts documents from the command line. Its `--headless` option runs without a user interface, and `--convert-to pdf` writes the PDF to the current directory, or to the folder given with `--outdir`. For example, the agent can run: ```bash sanbox exec --cwd /workspace/output -- soffice --headless --convert-to pdf summary.docx ``` Check complex layouts in Microsoft Word or Excel before you send them. LibreOffice and the Python libraries write standard files, but they aren't Microsoft Office. ## Slides (PowerPoint): enabled on request The OpenCode Computer doesn't make slide decks today. A slides-capable office Computer, with tools for PowerPoint files, is enabled per organisation on request: [Enable it for your organisation](mailto:sales@sanlabs.ai?subject=Enable%3A%20Slides-capable%20office%20Computer). ## Snapshot it If your team adds its own templates, fonts or helper scripts, set them up once, stop the Computer and snapshot it: ```bash sanbox snapshots create --run --name office-base --wait sanbox run --snapshot office-base --json ``` Each run from the snapshot starts with those files already in place. ## What this doesn't do - **Slides.** No python-pptx and no LibreOffice Impress. - **Microsoft Office.** Files are made with open-source tools, so check formatting that depends on Word or Excel. - **Huge files.** Artifact downloads are limited to 256 MiB per file, and the disk is 1 to 8 GB. - **Files outside `/workspace/output`.** Only that folder is exported as artifacts. Use `sanbox cp` for anything else. ## Related - [How do I give every employee their own AI agent computer?](https://sanbox.cloud/kb/teams/agent-computer-for-every-employee/) - [How do I run OpenCode as a server on a remote computer?](https://sanbox.cloud/kb/coding-agents/opencode-server-on-a-remote-computer/) - [How do I run 10 coding-agent tasks in parallel without them clashing?](https://sanbox.cloud/kb/parallel-work/run-coding-agent-tasks-in-parallel/) - [What survives when an agent's computer stops?](https://sanbox.cloud/kb/agent-computers/what-survives-a-stop/) ## Sources - LibreOffice Help, [Starting LibreOffice with parameters](https://help.libreoffice.org/latest/en-US/text/shared/guide/start_parameters.html) (`--headless`, `--convert-to`, `--outdir`), checked 2026-11-06 ## Next step Talk to us at sales@sanlabs.ai.
