  |desc-td = Removes category links from wikitext, including categories generated by templates.
  |desc-td-en = This template strips categories from wikitext. It can also remove categories generated by transcluded templates.
  |desc               = This template strips [[w:en:Help:Category|categories]] from [[w:en:Help:Wiki markup|wikitext]]. For example, if passed the code "<code><nowiki>foo[[Category:Some category]]</nowiki></code>", it will return only "<code>foo</code>". It can be used to strip categories from templates as well; if passed the code "<code><nowiki>{{my template}}</nowiki></code>", it will return the template output minus the categories.

The template properly handles categories escaped with the [[w:en:Help:Colon trick|colon trick]], categories whose names include invalid characters such as "<code>></code>", and categories that are surrounded with [[w:en:WP:NOWIKI|nowiki]] tags. However, it does not support complex wikitext such as nested links or [[w:en:WP:MAGIC|magic words]] like <code><nowiki>__TOC__</nowiki></code>. Even so, it should still remove the vast majority of categories from any given wikitext.
    |desc-td-en       = This template strips categories from wikitext. For example, if passed the code "<nowiki>foo[[Category:Some category]]</nowiki>", it will return only "foo". It can be used to strip categories from templates as well; if passed the code "<nowiki>{{my template}}</nowiki>", it will return the template output minus the categories.
