Automated Batch Translation Workflow for PDF Files

This workflow can automatically batch translate PDF documents in a Google Drive folder, supporting multiple languages and utilizing the DeepL translation API to ensure translation quality. It automatically filters the files to be translated, downloads them, and sends translation requests while monitoring the translation progress. Once the translation is complete, it automatically uploads the files back to the original folder. This process eliminates the cumbersome nature of manual translation and enhances the efficiency of handling multilingual documents, making it suitable for users such as businesses, content creators, and educational institutions that require quick translations.
