Translate PPT
Translate Chinese PowerPoint presentations (.pptx) to English with professional business styling.
Overview
This skill translates Chinese PPTX files to English using any OpenAI-compatible LLM endpoint (local or cloud). It preserves all non-text content while:
- Preserving all non-text content (images, charts, shapes, tables, SmartArt, media)
- Adjusting fonts to Calibri family for consistent business styling
- Optimizing text box sizing and layout for English text (typically longer than Chinese)
- Maintaining original slide masters, layouts, animations, and transitions
Prerequisites
- Python 3.8+
- Required packages:
python-pptx,requests - An LLM endpoint that supports OpenAI-compatible API (e.g., Qoderwork built-in models, Ollama, OpenAI, DeepSeek, etc.)
Quick Start
Option A: Use with Qoderwork (Easiest — No Extra Setup)
If you're running this skill within Qoderwork, models are already available. Just run:
pip install python-pptx requests
python .qoder/skills/translate-ppt/scripts/translate_ppt.py input.pptx --api-base <qoderwork-endpoint> --model <available-model>Option B: Use with Local Ollama
- Install Ollama:
Download and install from https://ollama.com
- Pull a recommended model:
ollama pull qwen2.5:14b- Install Python dependencies:
pip install python-pptx requests- Run translation:
python .qoder/skills/translate-ppt/scripts/translate_ppt.py input.pptxIf output path is not specified, defaults to <input_name>_en.pptx.
Option C: Use with Cloud API
Run with your cloud endpoint:
python .qoder/skills/translate-ppt/scripts/translate_ppt.py input.pptx --api-base https://api.openai.com/v1 --api-key sk-xxx --model gpt-4oTranslation Rules
- Translate: All text content (titles, body text, notes, table cells, grouped shape text)
- Preserve: Images, charts data, embedded media, hyperlinks, original formatting
- Mixed content: Only translate Chinese portions of mixed Chinese/English text
Font & Layout Adjustments
| Element | Font | Style |
|---|---|---|
| Titles | Calibri | Bold |
| Body text | Calibri | Regular |
- Maintain original font sizes (with auto-shrink if text overflows)
- Adjust text box width up to 20% if English text is significantly longer
- Preserve original color scheme and text formatting (bold, italic, underline)
Business Style Guidelines
- Consistent Calibri font family throughout
- Clean, professional spacing
- Preserved slide master/layout templates
- All animations and transitions intact
Recommended Models
Translation quality varies significantly between models. Choose based on your setup:
Note for Qoderwork users: You can use whatever models are already configured in your client environment — no additional setup required.
| Model | Size | Quality | Speed | Command |
|---|---|---|---|---|
qwen2.5:14b | ~9GB | ★★★★★ Best for Chinese | Fast | ollama pull qwen2.5:14b |
qwen2.5:7b | ~4.7GB | ★★★★ Good balance | Faster | ollama pull qwen2.5:7b |
llama3.1:8b | ~4.7GB | ★★★ Decent | Fast | ollama pull llama3.1:8b |
gemma2:9b | ~5.4GB | ★★★ Decent | Fast | ollama pull gemma2:9b |
qwen2.5:3b | ~2GB | ★★ Basic | Fastest | ollama pull qwen2.5:3b |
Tip: For best results with Chinese-to-English business content, Qwen2.5 14B is strongly recommended as it has excellent Chinese language understanding. Smaller models may produce less accurate or less natural translations.
Command-Line Options
| Option | Description | Default |
|---|---|---|
--font | Override default font | Calibri |
--model | LLM model to use | qwen2.5:14b |
--api-base | OpenAI-compatible API base URL | http://localhost:11434/v1 |
--api-key | API key (optional, not needed for local models) | None |
--batch-size | Text segments per API call | 20 |
--verbose, -v | Enable detailed logging | False |
Troubleshooting
| Issue | Solution |
|---|---|
| Connection refused | Check your API endpoint URL. For Ollama: ensure ollama serve is running. For cloud APIs: verify the URL is correct. |
| Model not found | Verify the model name is correct for your endpoint. For Ollama: ollama pull <model> |
| Corrupt PPTX | Verify file opens in PowerPoint; try saving as new file first |
| Font not found | Ensure Calibri is installed on your system |
| API rate limits | Reduce --batch-size or add delay between calls |
