Is your WordPress theme or website built with inline Schema.org Microdata? As search engines increasingly prefer the JSON-LD format for structured data, updating your site can be a significant challenge. Manually removing old Microdata and creating new JSON-LD scripts for every page is tedious and prone to errors.
The Microdata to JSON-LD Converter solves this exact problem. This plugin seamlessly automates the entire conversion process:
<ol>
<li>Scans Your Pages: It fetches the full HTML of your published posts and pages, ensuring it captures all Microdata, whether it’s in your post content or your theme files (like <code>header.php</code>).</li>
<li>Converts to JSON-LD: It intelligently parses the <code>itemscope</code>, <code>itemtype</code>, and <code>itemprop</code> attributes and converts them into a well-structured JSON-LD script.</li>
<li>Removes Inline Microdata: Optionally, it can clean up your public-facing HTML by removing the now-redundant Microdata attributes, leaving only the clean JSON-LD script in the <code><head></code>.</li>
<li>Keeps It Fresh: With the “Keep up to date” option, the plugin can automatically regenerate the JSON-LD every time you update a post, ensuring your structured data always reflects your latest content.</li>
</ol>
Key Features:
<ul>
<li>Full Page Parsing: Accurately reads Microdata from the entire webpage, not just post content.</li>
<li>Automatic Generation: Automatically creates the initial JSON-LD when you open a published post for the first time.</li>
<li>Manual Control: View and edit the generated JSON-LD directly in a meta box on each post’s edit screen.</li>
<li>Built-in Validator: Get instant feedback on your schema with a built-in validator that checks for common required and recommended properties.</li>
<li>Bulk Rebuild Tool: Process your entire site at once with a batch-processing tool that works through all your posts and pages.</li>
<li>“Set It and Forget It” Mode: Enable the “Keep JSON-LD up to date” option to ensure your structured data remains current.</li>
<li>Clean & Modern UI: A simple, intuitive settings page with toggle switches and tabs makes configuration a breeze.</li>
</ul>
This plugin offers a seamless migration path for modernizing your site’s SEO and structured data implementation, eliminating the need to edit your content, plugins, and theme files.

WordPress HTML editor (tinyMCE) treats schema.org attributes like itemscope/itemtype/itemprop as invalid HTML attributes and strips them when you save the post or page content. This plugin alters this behavior and prevent the WordPress HTML editor from removing the schema.org/microdata markup.
