Automate Document Filing with Gemini OCR in Google Drive

Transform your document chaos into an organized, searchable archive with this powerful Google Drive automation workflow. Using Gemini 2.5 Flash OCR technology, this n8n workflow automatically classifies, renames, and files documents from your inbox folder while tracking deadlines and logging everything in Google Sheets.

What this workflow does

The workflow monitors your designated Google Drive inbox folder and processes documents through an intelligent classification system. It retrieves files, loops through each document, and downloads them for processing. The system checks file types, routing PDFs and images to Gemini OCR classification while handling unsupported formats with error notifications and manual review logging.

Once Gemini OCR classification analyzes the document content, the workflow parses the AI response and generates appropriate filenames based on document type. Successfully classified files are automatically renamed, moved to their designated folders, and logged in your Google Sheets tracking system. When documents contain deadlines, the workflow creates Google Calendar events and sends Gmail alerts to ensure nothing falls through the cracks.

Use cases

• Accounting firms automatically sorting invoices, receipts, and financial documents by client or category
• Office managers organizing contracts, agreements, and administrative paperwork
• Small businesses streamlining document intake from email attachments and scanned files
• Legal offices classifying case documents and tracking important filing deadlines

Technical details
