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 error-prone.
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>
<li>Homepage WebSite Schema: Automatically generates WebSite JSON-LD for your homepage, complete with a Sitelinks Search Box to improve your site’s search presence.</li>
<li>Dynamic Archive Schema: Automatically constructs lightweight CollectionPage and ItemList JSON-LD schema for Category and Tag pages, matching Google’s exact specifications for list data without slowing down your server.</li>
<li>Knowledge Graph Auto-Linking: Automatically identifies standalone entities (like Local Businesses) and links them to your main Article schema using dynamic <code>@id</code> references for a unified data graph.</li>
</ul>
This plugin offers a seamless migration path to modernize your site’s SEO and structured data implementation, eliminating the need to edit your content, plugins, or theme files.
