How to convert post tags to categories in WordPress. You don’t need to install any additional plugin or performing SQL queries directly on the WordPress database. Tag to category converter (and vice versa) already exists in WordPress.
# navigation to the WordPress categories and tag converter (1) Dashboard -> Posts -> Categories -> category to tag converter (page bottom at right) # navigation to the WordPress categories and tag converter (2) Dashboard -> Tools -> Import -> Categories and Tags Converter # inside converter [Tags to Categories] (top button) -> check tag -> [Convert Tags to Categories] (bottom button)
In my case I wanted to create a subcategory with several posts. This posts were tagged with tag which should become a category. In Categories and Tags Converter I choose tags to categories conversion (you will see a button at page top). Tool will list all tags used in blog, so check tag and click on button “Convert Tags to Categories” at page bottom. A new category should appear in a list with included posts.
