Generate Accessible Alt Text with Claude AI from Sheets to WordPress

This workflow automates the generation and application of accessible alt text for WordPress media files using Claude AI. It reads image URLs and corresponding WordPress media IDs from a Google Sheet, analyzes each image with Anthropic's Claude AI to create concise, compliant descriptions (max 125 characters), updates the sheet with the results, and pushes the alt text to the WordPress media library via REST API. Error handling ensures unsupported formats are skipped, allowing seamless processing of large batches.

Ideal for WordPress site owners, content managers, and accessibility advocates, it streamlines compliance with WCAG standards, boosts SEO through better image descriptions, and saves hours of manual work. Use cases include bulk-updating existing media libraries, onboarding new image sets, or maintaining accessibility during content migrations.

Key benefits include AI-powered accuracy for descriptive alt text, automated authentication via Base64 from sheet-stored credentials, loop-based processing for scalability, and robust error recovery. Setup requires a Google Sheet with media data, WordPress Application Passwords, Claude API key, and the Export Media URLs plugin for initial exports.
