Convert Google Drive PDFs into SEO blog HTML using OpenAI GPT-4.1

Overview

This workflow automatically converts PDF files stored in Google Drive into structured, SEO-optimized blog articles in HTML format.

It eliminates repetitive manual rewriting and formatting by transforming raw PDF content into publish-ready blog files.

What This Workflow Does

Retrieves all PDFs from a specified Google Drive folder
Processes each file sequentially using Split In Batches
Downloads and extracts text from each PDF
Generates a long-form SEO blog article using OpenAI
Ensures the output is structured in HTML format
Saves the final blog back to Google Drive as a .html file
Automatically converts the original .pdf filename to .html

How It Works

The workflow begins with a manual trigger and fetches files from a configured Google Drive folder.

Using Split In Batches, each PDF is processed one at a time. This prevents API rate limits, reduces memory load, and ensures stable execution.

The extracted text is passed to OpenAI with a structured prompt that defines:

Blog length
SEO formatting
Heading structure (H1, H2, H3)
Tone and writing style
HTML output format

The generated content is then saved as an HTML file in a destination Google Drive folder.

Requirements

Google Drive credentials
OpenAI credentials
Source folder containing PDFs
Destination folder for generated HTML files

Output

For every PDF processed:

A long-form SEO blog article is created
Output is saved in HTML format
The original filename is retained and converted from .pdf to .html

Customization

You can modify:

The OpenAI prompt to change tone or niche
Blog length and SEO requirements
Destination folder
Output format if integrating with a CMS

This template is suitable for content teams, product managers, and creators who want to automate repetitive content transformation workflows while maintaining consistent output quality.
