🎯 What This Does

Automatically finds PDF file in Google Drive and extracts information. Use it to pull out clean output. It then formats the output into a clean JSON object.

🔄 How It Works

1. Manual Trigger starts the process. 2. 🔎Find File: "Google Drive" node finds the PDF file/files in a specified folder and downloads it/them. 3. 📝Extract Raw Text: "Extract From File" node pulls the text content from the retrieval file/files. 4. ✅Output Clean Data: "Code" node refines the extracted content and runs custom code for cleaning and final formatting.

  3. Define Extraction Rules (Extract Files/File's Data):

    • Select File Type: Open node and click on the dropdown below "Operation" section, choose "Extract From PDF". Next, in "Input Binary Field" section keep as default "data".

  5. Activate and Run:

    • Save and Activate the workflow.
    • Click "Execute Workflow" to run it manually and check the output.
