HTML to Blocks Converter

This plugin converts raw HTML content into Gutenberg block arrays, using WordPress Core's HTML API for spec-compliant parsing. It is designed for developers migrating legacy content, importing from external sources via REST API, or programmatically creating posts with block-based structure. It works in two modes: as a standalone plugin that automatically converts HTML on post save and REST editor reads, or as a Composer package for direct integration.

• Automatic conversion on save and read: Hooks into wp_insert_post_data and REST API edit context to convert raw HTML to blocks without manual intervention. No "Convert to blocks" prompt needed.
• Direct programmatic conversion: Call html_to_blocks_raw_handler() with an HTML string to get a block array, then serialize with serialize_blocks(). Useful for adapter pipelines or custom import scripts.
• Composer package support: Install via composer require chubes4/html-to-blocks-converter and load inside WordPress. The version registry ensures only the newest loaded copy initializes, avoiding conflicts when multiple plugins bundle the package.
• Extensive block transform coverage: Converts headings, paragraphs, lists, blockquotes, images, galleries, embeds, tables, code blocks, separators, and more. Unsupported elements are preserved as core/html with a fallback action for logging.
• Filterable post type support: Use html_to_blocks_supported_post_types to enable conversion on custom post types. Defaults to all public REST-enabled post types.
