Transform HTML from WordPress, Drupal, or any CMS into clean, structured Portable Text JSON. Perfect for large-scale CMS migrations and legacy content modernization.
Your content is trapped in HTML; thousands of articles wrapped in <div> soup, inline styles, and deprecated tags from 2010. Maybe it's a WordPress export, a Drupal database dump, or years of accumulated HTML from various CMSes. Now you're moving to Sanity, and that HTML needs to become clean, structured Portable Text.
Manual conversion is impossible at scale. A single HTML article with nested divs, custom classes, and inline styles takes 45+ minutes to clean and convert. For a typical site with 1,000+ pages, that's 750 hours of mind-numbing work.
Our HTML to Portable Text converter automatically transforms messy HTML into clean Portable Text JSON. It strips unnecessary markup, preserves semantic meaning, and outputs properly structured content ready for Sanity. No more manual cleaning, no more lost structure, no more migration nightmares.
The HTML Migration Challenge
HTML was designed for browsers, not content management. Over years, your HTML content accumulates cruft: inline styles from old editors, wrapper divs from ancient themes, class names from deprecated frameworks. This presentation-focused markup makes content migration a nightmare.
Anatomy of Legacy HTML Hell
Here's what typical CMS HTML looks like after years of accumulation:
With 40% of the web running on WordPress, millions of sites need modern content infrastructure. WordPress stores content as HTML in the database, making Sanity migration complex.
Projected numbers:
Average WordPress site: 500+ posts
Manual conversion time: 30 minutes per post
Total migration time: 250+ hours
Cost at $50/hour: $12,500
Legacy CMS Modernization
Organizations running Drupal, Joomla, or custom CMSes from the 2000s have massive HTML content stores that need modernization.
Projected numbers:
15,000 pages of HTML content
Manual migration quote: $375,000
Automated conversion: $15,000
Savings: $360,000
Static Site Conversions
Companies moving from static HTML sites or Jekyll/Hugo to Sanity need to convert years of accumulated HTML content.
Projected numbers:
90% reduction in migration time
Preservation of all semantic structure
Clean, queryable content in Sanity
Enterprise Content Consolidation
Enterprises consolidating multiple CMSes into Sanity face diverse HTML formats from different systems.
