Unlock Bank Statement Insights with AI-Powered PDF to Markdown Conversion
detail.loadingPreview
Transform your bank statements into structured markdown effortlessly. This n8n workflow leverages cutting-edge Vision Language Models (VLMs) to accurately capture details from scanned or downloaded PDFs, making data extraction simpler than ever.
About This Workflow
This powerful n8n workflow automates the conversion of bank statements into markdown format, faithfully preserving crucial document details. By utilizing Vision Language Models (VLMs), it excels at interpreting complex layouts, including tables and columnar data, which traditional OCR might struggle with. The process begins by downloading your bank statement from Google Drive, then efficiently splits PDF pages into individual images. These images are processed by a Google Gemini Vision model to generate markdown text. This structured output can then be further analyzed by standard Large Language Models (LLMs) to extract specific information, such as identifying deposit table rows.
Designed for flexibility, this workflow handles both digital and scanned PDFs. Prioritize data privacy by ensuring sensitive information is protected before execution. Get started quickly with the provided example bank statement and leverage the n8n community for support.
Key Features
- AI-Powered Transcription: Utilizes Vision Language Models (VLMs) for intelligent interpretation of PDF content, going beyond simple OCR.
- Handles Scanned & Digital PDFs: Adaptable to various document sources.
- Preserves Table and Columnar Data: Generates markdown that faithfully represents structured information.

How To Use
- Download Bank Statement: Configure the 'Get Bank Statement' node to access your bank statement PDF, either by providing a direct Google Drive file ID or by swapping it for a different trigger like a webhook.
- Split PDF into Images: The 'Split PDF into Images' node (using Stirling PDF) converts each page of your PDF into a separate image file.
- Extract Images: The 'Extract Zip File' node unpacks the images generated in the previous step.
- Create Image List: The 'Images To List' code node structures the extracted images into a list, ready for AI processing.
- Resize Images (Optional but Recommended): The 'Resize Images For AI' node optimizes image dimensions for efficient processing by the AI model, helping to manage token limits.
- Convert Images to Markdown: The 'Google Gemini Chat Model' node (configured as a Vision model) processes each image to transcribe its content into markdown. Ensure your Google Gemini API credentials are set up.
- Test and Refine: Use the 'When clicking ‘Test workflow’’ trigger to run the workflow and review the generated markdown output. Adjust node parameters, especially for the AI model, based on your results and specific needs.
