PPT Chinese to English Conversion Assistant

Problem

This skill addresses a narrow but common office task: a PPTX deck contains Chinese text and must be delivered in English, while preserving the existing layout. Simple find-and-replace is not enough because some decks mix Chinese in text boxes, native tables, and charts rendered as images.

How It Works

The skill first checks where the Chinese appears. If all Chinese is in text boxes, it uses in-place replacement: extract Chinese paragraphs, build a translations.tsv dictionary, and replace runs with a longest-first matching order, then verify that no Chinese characters remain. If Chinese is embedded inside images, it switches to a chart-redrawing workflow: infer chart content from user input or surrounding text, regenerate the chart with Python and matplotlib, and embed the English chart back into the slide. It also standardizes terminology, for example using HCC for hepatocellular carcinoma instead of a bare organ name.

Boundaries

It works best on stable PPTX files with text boxes, native tables, or redrawn charts. It is less reliable for complex vector graphics, heavy animations, embedded objects, or image text that cannot be reconstructed from context. Chinese quotation marks, split text runs, large files, and residual Chinese inside images are the main things to check.
