Everything below this line is a demo of Format TemplateData: read the source code, and expand the raw TemplateData section, to see how it all works.
== Usage ==
{{Format TemplateData|1=
<templatedata>
{
	"description": "This template formats [[WP:VE/TD|TemplateData]] nicely on doc pages. It hides irrelevant information such as \"Default: empty\", and allows the use of formatting. Remember that the users of VisualEditor '''will not see''' this formatting; it is important to test your new TemplateData in VisualEditor to check that it makes sense without. (For all details of formatting available, see the template's page.) By default, {{[[Template:TemplateData header|TemplateData header]]}} is automatically inserted before the table.",

		"1": {
			"label": "<templatedata> template information",
			"description": "If the JSON and TNT parameters are not specified, this will be processed to extract the JSON. This option allows you to use the GUI TemplateData Editor, but it's a bit wonkier than giving the actual JSON object directly.",
			"default": "See {{{JSON}}}.",
			"type": "string"
		},
		"JSON": {
			"label": "JSON template information",
			"description": "The code that would normally be wrapped in [[WP:TemplateData|&lt;templatedata&gt;]] tags (not including the &lt;templatedata&gt; tags themselves. Links and basic text formatting should just work in the displayed table; see this template's page for full details. You should use HTML entities for special characters such as &lt;&gt;. <noexport><h3>Formatting options</h3>\n*'''Wikilinks''' can be specified in the usual way. They will only work in the table; in VisualEditor, the title of the link will be displayed as plain text.\n*'''External links''' can be specified by just inserting the URL; this will be clickable in the table and viewable in VisualEditor. If the URL is specified as &#91;https:&#47;&#47;en.wikipedia.org Wikipedia&#93;, this will appear as [https://en.wikipedia.org Wikipedia] in the table and https:&#47;&#47;en.wikipedia.org in VisualEditor.\n*'''[[HTML entities]]''': you may specify &amp;lt; &amp;gt; &amp;amp; &amp;quot; &amp;nbsp; and any numeric entity.*'''HTML tags''' may be used; they won't appear in VisualEditor.\n*'''&lt;noexport&gt;&lt;/noexport&gt;''' Content wrapped in these tags will appear only in the table. It will not appear in VisualEditor at all; it is useful for detailed explanations of parameters, and for content that is only useful with formatting. Newline characters are respected here.\n*'''Templates''' may be transcluded. However some templates may output content that makes the JSON invalid.</noexport>",

== Using the template ==
Add the <code>&lt;templatedata&gt;</code> as usual, and then enclose it in a template call like <code><nowiki>{{Format TemplateData|1=<templatedata>...</templatedata>}}</nowiki></code>.

==Maintenance categories==
* {{clc|Templates with TemplateData errors}} – the template adds this category to template documentation pages with malformed TemplateData code.
