<h4>Why use this plugin?</h4>
<p>Over time, WordPress sites accumulate post meta data from plugins, themes, and page builders. When you switch or remove plugins, their meta often stays in the database — bloating tables, slowing queries, and making backups larger. Post Meta Editor and Cleaner gives you direct control over this data.</p>
<h4>Key benefits</h4>
<ul>
<li><strong>Database optimization</strong> — Remove orphaned meta from deleted plugins to reduce database size and improve performance.</li>
<li><strong>Source identification</strong> — See which plugin or theme created each meta key. The built-in source map recognizes 50+ popular plugins (WooCommerce, Yoast, Rank Math, Elementor, Jetpack, WPML, and many more).</li>
<li><strong>Bulk delete</strong> — Delete more meta keys at once. Adjust process speed to avoid timeouts on large sites.</li>
<li><strong>Search and replace</strong> — Update URLs, domain names, or text across all posts. Works with serialized data (arrays, objects) — both values and keys can be updated.</li>
<li><strong>Flexible deletion</strong> — Delete the entire meta key and its values, or clear values only while keeping the key structure.</li>
<li><strong>Safe editing</strong> — Overwrite meta values in bulk, or perform targeted search-and-replace. Ideal for migrations, domain changes, or fixing incorrect product data.</li>
</ul>
<h4>What you can do</h4>
<ul>
<li>Clean up after removing plugins or themes.</li>
<li>Migrate a site and update old URLs in meta fields.</li>
<li>Fix WooCommerce product attributes, SEO meta, or custom fields in bulk.</li>
<li>Identify and remove unused or duplicate meta keys.</li>
<li>Reduce <code>wp_postmeta</code> table size for faster backups and queries.</li>
</ul>
<h4>Important</h4>
<p>Before making any changes, create a backup, as modifications and deletions can only be restored from a backup.</p>

Post Meta Editor and Cleaner by RotiStudio

Post Meta bulk editor to delete unused data, overwrite values, run search and replace, and clean your database directly from the admin panel.

JS Morisset

<p>The JSM Show Post Metadata plugin displays post (ie. posts, pages, and custom post types) meta keys (aka custom field names) and unserialized values in a metabox at the bottom of the post editing page.</p>
<p>Note that if you’re using WooCommerce HPOS (High-Performance Order Storage), available since WooCommerce v8.2, then your WooCommerce orders are NOT post objects and you should use the <a href="https://wordpress.org/plugins/jsm-show-order-meta/" rel="ugc">JSM Show Order Metadata</a> plugin instead.</p>
<p>There are no plugin settings – simply install and activate the plugin.</p>
<h4>Available Filters for Developers</h4>
<p>Filter the post meta shown in the metabox:</p>
<pre><code>'jsmspm_metabox_table_metadata' ( array $metadata, $post_obj )

<p>Array of regular expressions to exclude meta keys:</p>
<pre><code>'jsmspm_metabox_table_exclude_keys' ( array $exclude_keys, $post_obj )
</code></pre>
<p>Capability required to show post meta:</p>
<pre><code>'jsmspm_show_metabox_capability' ( 'manage_options', $post_obj )
</code></pre>
<p>Show post meta for a post type (defaults to true):</p>
<pre><code>'jsmspm_show_metabox_post_type' ( true, $post_type )

JSM Show Post Metadata

I've started recently to use this plugin to discover post meta values, I must say it's cleaner than other plugins I've used before.

Thanks for the latest update release 2.0.0, the ability to have post meta updated without having to load the page is pretty awesome.

I use the plugin almost everyday. I recommend it to anyone who wants to see what's in post meta.

Keep it up!

Useful and Very Clean Post Meta Viewer Plugin

It's great for letting me see hidden metadata without having to open up the database.  Plus, it's great for allowing non-technical users to see the information without the risk of sending them to the database.  

Super helpful tool!


I'm definitely not making full use of its potential but, for what I need it, it has proved to be dependable and very useful.



Thank you for sharing your work.

This plugin is incredibly helpful when converting and managing legacy websites, especially for uncovering all kinds of hidden metadata - even the obscure ones.


Thanks a lot for this great plugin!

Show post metadata (aka custom fields) in a metabox when editing posts / pages - a great tool for debugging issues with post metadata.
