Extract data from resume and create PDF with Gotenberg n8n Workflow Template

n8n workflow template · 31 nodes · OpenAI

Extract data from resume and create PDF with Gotenberg is a free n8n workflow template that starts from the Telegram Trigger node and works with OpenAI and Telegram. It has 31 nodes, 5 of them AI nodes (OpenAI Chat Model, Auto-fixing Output Parser, Structured Output Parser and Basic LLM Chain). The notes inside the workflow say: “Remember to set your actual ID to trigger automation from Telegram.” To run it, you add your own credentials for OpenAI API and Telegram Bot API.

How it works

The text below comes from the sticky notes inside the workflow. We removed links, code samples and anything that looks like a key or token.

Add chat ID

Remember to set your actual ID to trigger automation from Telegram.

Ignore start message

Workflow ignores initial/start message sent to the bot.

Download resume file

Based on file ID, node performs downloading of the file uploaded by user.

Extract text from PDF

Node extracts readable text form PDF.

Parse resume data

Create structured data from text extracted from resume. Chain uses OpenAI gpt-4-turbo-preview model and JSON response mode. Adjust JSON schema in output parser to your needs.

Format HTML

Format HTML for each resume section (employment history, projects etc.).

Create HTML file

From formatted output create index.html file in order to run PDF conversion.

Convert file to PDF

Form index.html create PDF using Gotenberg. If you're not familiar with this software, feel free to check out my tutorial on YouTube.

Send PDF file to user

Deliver converted PDF to Telegram user (based on chat ID).

Note

This is resume extractor workflow that I had a pleasure to present during n8n community hangout on March 7, 2024.

  1. Remember to add your credentials and configure nodes.
  2. This node requires installed Gotenberg for PDF generation. If you're not familiar with this software, feel free to check out my tutorial on YouTube. If you don't want to self-host Gotenberg, you use other PDF generation provider (PDFMonkey, ApiTemplate or similar).
  3. If you like this workflow, please subscribe to my YouTube channel and/or my newsletter.

Thank you for your support!
