AI-powered auto-translate Google Slides presentation to any language with Gemini

💬🗂️🤖 This workflow automates the translation of Google Slides presentations from any languages, while preserving the original formatting and slide structure. It leverages Google APIs, AI translation (Gemini/PaLM), and modular execution for high flexibility and accuracy.

DISCLAIMER: texts are split by Google Slides APIs into small blocks, so the translation will not always be contextualized.

Key Benefits

⚡ Time-Saving: Automates a typically manual and error-prone task of translating slides. 🌍 AI-Powered Accuracy: Uses Google Gemini to provide context-aware translations while respecting defined rules. 🔒 Safe & Non-Destructive: The original presentation is never modified — a new copy is always created. 🎯 Precision: Skips irrelevant text (e.g., emails, URLs, names) to avoid mistranslation. 🔁 Modular & Scalable: Uses subworkflows and batching, ideal for presentations with many slides. 🎨 Layout Preservation: Keeps the original design and formatting intact.

How it Works 1. Initialization: - The workflow starts with a manual trigger ("When clicking ‘Execute workflow’"). - Set the language to translate (IMPORTANT format ISO-639) - It duplicates a specified Google Slides presentation ("Duplicate presentation") to create a new copy for translation, preserving the original.

2. Slide Processing: - The workflow retrieves slides from the copied presentation ("Get slides from a presentation") and processes them in batches ("Loop Over Items"). - For each slide, text content is extracted ("Extract Text") using a custom JavaScript snippet, which identifies and collects text elements while retaining the slide's objectId.
