An AI-assisted presentation utility to translate PowerPoint decks between English and Chinese while retaining layouts, styles, and images.

This tutorial shows how to configure, use, and integrate the PPTX Translation Skill to translate presentations seamlessly without losing layout integrity or typography.

It supports dual-direction translation (zh2en and en2zh) and integrates directly with AI agent platforms.

1. Overview

Translating slides can be tedious because text expansion often breaks layout containers, font sizes, and line-breaks.

This utility addresses this issue by translating text blocks at the paragraph level (preserving text runs), cleaning target punctuation automatically, replacing fonts intelligently, and running automated quality checks for formatting consistency.

2. Translate entries: Edit trans.json and fill in the translated fields.
3. Write back translated text:

   python scripts/translate_pptx_inline.py --mode apply --direction zh2en -i source.pptx -t trans.json -o target.pptx
