Remove Schema optionally removes all schema markup from your website. <a href="http://coderisk.com/wp/plugin/remove-schema/RIPS--IjmGY49ry" rel="nofollow ugc"></a>
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

Thanks for installing this simple plugin!
<ul>
<li>Use different JSON-LD markup on every page and post, if needed!</li>
<li>Use any valid JSON-LD type or class available! With this plugin, you aren’t limited to whatever form fields a developer decides to include.</li>
</ul>
Use any schema type you want! This plugin allows you to easily add highly customized JSON-LD schema markup to your pages and posts. For the most part, this is not a fill-in-the-blanks plugin. You must first create nearly all of the markup on your own. Check out the <a href="http://schema.org/docs/full.html" rel="nofollow ugc">Schema Docs</a> to help build your markup.
There are convenient ‘Author’ and ‘Website’ fill-in-the-blank form fields available for every post. I may add more in the future.
To ensure changes to your page or post markup, be sure to click the normal WordPress ‘Update’ button for the respective page or post.
IMPORTANT 
The plugin automatically adds the appropriate script tags to the header page, so don’t add them as part of your structured JSON-LD markup inside of the meta boxes.
So, when adding a single item to a meta box, it might look similar to this:
{ “@context”: “http://schema.org”, “@type”: “Organization”, “url”: “http://yourorganization.com”, “name”: “Your Organization Name” }
When adding more than one item to a meta box, use brackets around all items and separate with commas; something similar to this:
[ {“@context”: “http://schema.org”, “@type”: “Organization”, “name”: “Your Organization Name”, “url”: “http://your-organization.com” }, {“@context”: “http://schema.org”, “@type”: “Person”, “name”: “Your Name”, “url”: “http://your-personal-site.com” } ]

Open Schema Data

Add any valid schema type to your pages and posts using JSON-LD markup.
