Improve Website Accessibility: GPT-4o Alt Text Generator & Google Sheets

This n8n workflow enhances website accessibility by analyzing HTML pages for image alt texts. It downloads the page content, extracts all <img> tags with their src and alt attributes using a Code node, and identifies missing or insufficiently descriptive alts (under 50 characters).

Leveraging GPT-4o with vision capabilities, it generates rich, context-aware alt descriptions for flagged images directly from their URLs. Results are stored and updated in a Google Sheet, providing a centralized audit log for easy tracking and implementation.

Ideal for bloggers, SEO specialists, web developers, and product teams, this automation saves hours of manual auditing, boosts WCAG compliance, improves search rankings, and promotes inclusive web practices. Set your URL and run to transform accessibility effortlessly.
