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.

<h3>Where The Heck Am I?</h3>
Let’s face it: breadcrumbs are an integral part of websites these days. They give an immediate sense of hierarchy to your visitors and allow users to backtrack through your site to (hopefully) find more content. WordPress simplifies structuring sites how ever it seems reasonable, but it takes a bit more effort to generate breadcrumbs for all the different types of posts, and pages, and taxonomies, and archives, and … you get the idea.
<h3>But there are already plugins for that, aren’t there?</h3>
Sure! And a lot of them work really well for simple sites with simple hierarchies, but many of them fall short in one way or the other:
<blockquote>
Want to use the new semantic <code><nav></code> element? 
 Nope sorry, all they have are <code></code>‘s or <code><ul></code>‘s.
Need to control the classes or IDs of the crumbs? 
 Yep, nope; their wrapper has a fixed class of <code>breadcrumbs</code> though…I hope that’s all you need.
Uh…okay what about custom taxonomies? 
 You already know the answer to this question…
And custom post types? 
 Better hope they’re hierarchical!
Should I even bother mentioning rich snippets/microdata? 
 Haven’t found one yet.
</blockquote>
<h3>Okay fine, but what makes you think yours is any better?</h3>
It might be obvious (considering the previous section) that this plugin seeks to address all the customizability problems with the existing breadcrumb plugin environment while still keeping it as easy to use as possible (read: <code>HAG_Breadcrumbs();</code>, done!). It’s as simple as that. Hopefully it can live up to your expectations!
<h3>Features</h3>
The following features are currently available unless otherwise specifed.
<ul>
<li>
Simple Installation 
Upload the plugin, activate via the WordPress admin, and drop the function where you want the breadcrumbs to appear in your template. Done!
</li>
<li>
Fine-Tuned Control 
H&G works right out of the box, but oftentimes we want custom control. Nearly every aspect of the breadcrumbs rendering can be changed a’la the <a href="https://github.com/Clark-Nikdel-Powell/Hansel-and-Gretel#options" rel="nofollow ugc">myriad of options</a> available.
</li>
<li>
Microdata Integration 
H&G by default includes the microdata format for a <a href="http://schema.org/WebPage" rel="nofollow ugc">WebPage’s breadcrumbs</a>, a format that is jointly supported by <a href="http://www.bing.com/community/site_blogs/b/search/archive/2011/06/02/bing-google-and-yahoo-unite-to-build-the-web-of-objects.aspx" rel="nofollow ugc">Bing</a>, <a href="http://support.google.com/webmasters/bin/answer.py?hl=en&answer=1211158" rel="nofollow ugc">Google</a>, <a href="http://developer.yahoo.com/blogs/ydn/posts/2011/06/introducing-schema-org-a-collaboration-on-structured-data/" rel="nofollow ugc">Yahoo!</a> and <a href="http://help.yandex.ru/webmaster/?id=1122752" rel="nofollow ugc">Yandex</a>.
</li>
<li>
Full Markup Control 
Choose any element to wrap your breadcrumbs, including optional class(es) or ID attributes. Likewise, you can include prefix and suffix content right inside the wrapper element tags for further control.
</li>
<li>
Template Hierarchy Based Rendering 
H&G utilizes the <a href="https://codex.wordpress.org/Template_Hierarchy" rel="nofollow ugc">WordPress Template Hierarchy</a> to determine which crumbs to show, including that elusive Comments Popup Window everybody (read: nobody) uses! This means, regardless of your theme, Hansel & Gretel will follow WP’s lead about the content on the page.
</li>
<li>
Custom Post Types & Taxonomies 
Never worry about how breadcrumbs behave across your fancy new post types and taxonomies. H&G accounts for hierarchical and non-hierarchical types, whether or not they have an archive page, and also provides options to override breadcrumb display for individual post types if desired.
</li>
<li>
Home & Last Crumbs 
H&G allows full control in showing home breadcrumbs and even allows for customized Front Page versus Blog Home Page templates. Likewise, the last, current page crumb has equal control depending on the needs of your theme.
</li>
<li>
Made for Theme Developers 
Hansel and Gretel was made by theme developers for theme developers. The default options and degree of customizability were all considered by our team of experienced WP developers to make sense right out of the box, with as little further customization as possible. Give it a try and let us know what you think. We all want H&G to be the simplest and smartest breadcrumb plugin you’ll ever use! To contribute to the development of this plugin, <a href="https://github.com/Clark-Nikdel-Powell/Hansel-and-Gretel" rel="nofollow ugc">fork our repo</a> over on GitHub.
