Do you need to back up your post tags, migrate them to another site, or perform a bulk update in a spreadsheet? Post Tags Export/Import is the perfect tool for the job.
This plugin provides a simple interface under “Tools” in your WordPress admin area to handle two key tasks:
<ol>
<li>Export Posts to JSON: With a single click, you can download a clean JSON file containing the <code>title</code>, <code>slug</code>, and an array of <code>tags</code> for every post on your site.</li>
<li>Import Tags from JSON: Upload a JSON file (in the same format as the one you exported) to bulk update tags. The plugin uses the post <code>slug</code> to identify which post to update and replaces its existing tags with the ones from the file.</li>
</ol>
This is incredibly useful for: 
* Backing up and restoring tag structures. 
* Editing tags offline in bulk using a text editor or script. 
* Migrating tag information between staging and production environments. 
* Quickly applying a new set of tags to hundreds of posts.
The plugin is designed to be lightweight, secure, and easy to use.
