Unlock Insights from PDFs and Images with AI-Powered Text Extraction
detail.loadingPreview
Automate the extraction of text and structured data from PDFs and images, transforming unstructured content into actionable CSV files using Google's Vertex AI Gemini. This workflow streamlines data processing, saving you time and effort.
About This Workflow
This n8n workflow revolutionizes how you handle documents and visual data. It seamlessly integrates with Google Drive to detect new PDF or image files. Leveraging the power of Google's Vertex AI Gemini, the workflow intelligently extracts text content from these files. For PDFs, it utilizes a dedicated extraction node, while for images, it processes them directly. The extracted text is then sent to a powerful AI model (Gemini 1.5 Pro via OpenRouter) to perform advanced analysis, such as identifying transactions and categorizing them, transforming raw text into a structured CSV format. Finally, the generated CSV files are automatically uploaded back to your Google Drive for easy access and further use. This solution is perfect for automating repetitive data entry tasks and unlocking valuable insights from your documents.
Key Features
- Automated File Monitoring: Automatically detects new PDFs and images added to a designated Google Drive folder.
- Intelligent Text Extraction: Utilizes AI (Vertex AI Gemini) to accurately extract text from both PDF documents and image files.
- Data Structuring and Categorization: Transforms extracted text into a structured CSV format, including AI-driven categorization for better analysis.
- Seamless Google Drive Integration: Effortlessly uploads the generated CSV files back to your Google Drive.
How To Use
- Connect Google Drive: Authenticate your n8n instance with your Google Service Account for access to Google Drive.
- Configure Google Drive Trigger: Set the 'Google Drive Trigger' node to watch a specific folder (
Actual Budgetin the example) for newly created PDF or image files. - Define File Routing: Use the 'Route based on PDF or Image' node to direct PDF files to the PDF download and extraction path, and image files to the image download path.
- Download Files: Configure the 'Download PDF' and 'Download Image' nodes to retrieve the detected files from Google Drive.
- Extract and Process Text: For PDFs, use the 'Extract data from PDF' node. For images, the workflow will proceed to the AI processing step.
- AI Text Extraction and Structuring: Connect the 'Send data to A.I.' node (configured with OpenRouter and a suitable AI model like Llama 3.1) to process the extracted text. Customize the prompt to specify the desired output format (e.g., CSV with transaction details and categories).
- Convert to CSV: Employ the 'Convert to CSV' nodes to format the AI's output into a CSV file.
- Upload to Google Drive: Use the 'Upload to Google Drive' nodes to save the generated CSV files into a designated output folder (e.g.,
CSV Exports) in your Google Drive.
