Remove Schema optionally removes all schema markup from your website.
You have the option to remove:
<ul>
<li>All JSON-ld</li>
<li>All Microdata</li>
<li>All RDFa</li>
</ul>
And remove plugin/theme specific markup:
<ul>
<li>WooCommerce</li>
<li>WooCommerce emails</li>
<li>Yoast SEO</li>
<li>Schema Pro</li>
<li>GeneratePress themes</li>
</ul>

Remove Schema

Works great! I wanted to add my own schema, but the theme I am using was adding a bunch more, some of it in error. Remove Schema got rid of all that junk and everything's good now! 

Excellent - Removed Problematic Schema

Remove all Schema Markup / Structured data (Microdata, RDFa and/or JSON-ld) that you don’t want on your site.

Adds custom field to the post & pages editor for custom JSON-ld schema markup also known as structured data. The plugin also validates if the JSON is formated correctly. <a href="http://coderisk.com/wp/plugin/websitescanner-custom-schema/RIPS-8iSfZmxGFd" rel="nofollow ugc"></a>
Add your own JSON-ld on every page, post and custom post without the <code><script></code> to show your own custom Schema markup.
Works well with the following plugins:
<ul>
<li><a href="https://wordpress.org/plugins/remove-schema/" title="Remove Schema WordPress plugin" rel="ugc">Remove Schema</a></li>
</ul>
Usecases:
With the combination of the WordPress plugin it’s easy to overwrite the schema on a specific page. 
If a plugin like Yoast SEO or other plugin or theme that generates schema you can disable the schema and add your own custom schema to the page.
