PROJECT OVERVIEW
Managing large volumes of Chinese-language documents can be complex, time-consuming, and error-prone when handled manually. Organizations often require full English translations, structured categorization, and proper tracking of original and translated files.
To address this, we implemented a fully automated document translation and classification workflow using n8n integrated with Google Workspace and AI services.
The system automatically detects documents inside a shared Google Drive folder, translates complete Chinese PDFs into English (page by page), categorizes them using AI, and logs all structured metadata into Google Sheets without requiring manual intervention.
Objectives
Eliminate manual document translation processes
Ensure complete page-by-page translation (not summaries)
Preserve original document structure and formatting
Automatically categorize documents based on market relevance
Maintain structured tracking of original and translated files
Enable scalable processing of large document volumes
Centralize document metadata in a single tracking system
The Challenge
Organizations handling multilingual documentation often struggle with:
Manual processes increase turnaround time, risk data inconsistencies, and create operational bottlenecks across departments.
THE SOLUTION ARCHITECTURE (HOW DOES IT WORK?)
This automation demonstrates how intelligent workflow orchestration can streamline multilingual document processing by combining automated file detection, AI-powered full-document translation, structured PDF regeneration, and metadata tracking, the system creates a seamless end-to-end translation pipeline.
How does it work?
Step 1: Google Drive Monitoring
The workflow continuously monitors a shared folder in Google Drive and processes:
- All existing files
- Any newly uploaded documents
Step 2: File Download & Metadata Capture
Each detected file is downloaded and its metadata (file name and file ID) is captured for structured tracking.
Step 3: PDF Content Extraction
Using a PDF processing service, the document content is extracted page by page to ensure no data is lost.
Step 4: Full Document Translation
The extracted Chinese content is sent to an AI language model, which performs a complete English translation while preserving structure and meaning.
Step 5: English File Generation & Upload
A new English PDF is generated and uploaded back to Google Drive, maintaining reference to the original Chinese file.
Step 6: AI-Based Categorization
The translated content is analyzed to determine:
- Primary market category
- Secondary market category
Step 7: Structured Metadata Logging
A structured entry is added to Google Sheets containing:
- Original file name
- Translated file name
- Chinese file ID
- English file ID
- Primary category
- Secondary category
This creates a centralized, searchable document tracking system.
