About This Workflow

Overview

This workflow takes a PDF bank statement, splits it into individual image pages, and then uses a Vision Language Model (VLM) to convert each page into markdown text. This markdown preserves tabular data and structure, making it easier to process further with standard LLMs.

Key Features

Handles both downloaded and scanned PDFs.
Converts PDF pages to images.
Utilizes a VLM to extract text and structure into markdown.
Preserves tabular data from the bank statement.
Supports image resizing for AI processing efficiency.

How To Use

Trigger: Manually trigger the workflow or adapt it to use a different trigger (e.g., webhook).
Get Bank Statement: Configure the Google Drive node with the fileId of your bank statement PDF.
Split PDF: The workflow uses an external HTTP Request to a service that splits the PDF into multiple image files (e.g., JPG).
Extract Zip: The output from the PDF splitting service is a zip file, which is then extracted.
Images To List: This code node prepares the image files for the next step.
Resize Images: The editImage node resizes images to optimize processing by the AI model.
Google Gemini Chat Model: Configure the Google Gemini node with your API credentials. This node performs the core VLM task of converting images to markdown.
Sort Pages (Optional): The sort node can be used to ensure pages are processed in the correct order if needed.
Output: The output will be markdown text representing the content of the bank statement.
