Professional PPT One-Click Translation

Problem Solved

Translating a Chinese PPT deck into English is risky when text is translated fragment by fragment: sentence meaning can break, terminology may drift, and formatting such as font size, bold, color, and box position may be lost. This skill is for editing an existing Chinese PPTX and producing an English version that remains easy to tweak.

How It Works

• Paragraph-level translation: It merges multiple text runs in the same logical paragraph into one sentence, translates it, then writes the result back to the first run and clears the rest.
• Format preservation: It keeps positions, font size, bold, and color intact, changes the language attribute from zh-CN to en-US, and switches fonts toward a Latin-friendly option.
• Workflow: extract_text.py pulls body and notes text into JSON; the model fills each translated field; replace_text.py writes the results into a new PPTX.
• Boundaries: Image elements and page-number placeholders are skipped; child text boxes inside group shapes are processed recursively; longer English text may overflow a text box and may need manual resizing.
