Approved Template Link : Post Google News headlines to Instagram images with GPT-4o-mini, PDF API Hub and Google Sheets | n8n workflow template

I recently got one of my workflows approved and published on the official n8n template library, so sharing it here.

Workflow:

Auto-post Google News to Instagram with OpenAI, PDF API Hub & Google Sheets

What it does

  • Pulls latest articles from a Google News RSS feed (based on a topic)

  • Deduplicates entries using Google Sheets

  • Rewrites headlines into short captions using OpenAI (GPT-4o-mini)

  • Generates a branded image from HTML (via PDF API Hub)

  • Publishes the post to Instagram

  • Updates the sheet with status and image URL

Why I built this

I wanted a simple, reusable pipeline that connects RSS feeds, LLMs, and content publishing — all inside n8n — without needing any manual steps.

Setup (quick overview)

  • Create a Google Sheet for tracking

  • Connect credentials:

    • Google Sheets

    • OpenAI

    • PDF API Hub

    • Instagram

  • Set your topic (AI, crypto, etc.)

  • Optionally customize the HTML template

n8n has a Deduplication native node, if you want to simplify the flow and avoid using Excel

Nice one. It’s a good example of how n8n can connect discovery, enrichment, asset generation, and publishing in one flow without turning into a mess. The deduping step with Google Sheets is also a smart touch for keeping it practical in the real world.
