JKK URL Scout adds a Tools page that exports a list of post/page URLs (and related metadata) to a CSV file.
It is designed for large sites:
<ul>
<li>Exports in batches to reduce timeouts and memory usage.</li>
<li>No external requests, no tracking/telemetry.</li>
<li>Admin-only actions protected with capability checks and nonces.</li>
</ul>
The CSV includes common fields such as:
<ul>
<li>Post ID, post type, status, dates</li>
<li>Title, slug, parent ID, comment count</li>
<li>Permalink and edit link</li>
<li>Categories, tags</li>
<li>Author display name</li>
<li>Featured image URL</li>
<li>Page template</li>
</ul>
<h3>Notes (Japanese)</h3>
本プラグインは WordPress 管理画面の「ツール」配下に CSV エクスポート画面を追加し、投稿/固定ページ/カスタム投稿タイプの URL 一覧を CSV で出力します。 
大量件数のサイトでも動作しやすいよう、バッチ処理（分割取得）でのエクスポートを前提にしています。

The Plugin adds an link preview box to your post. 
The link preview box will be displayed like in Facebook! 🙂
This plugin can be used for free for maximal 10 URL Preview Boxes.
Perhaps you are familiar with Facebook. 
When you write a post in Facebook and you paste an URL into your text, 
Facebook detects that URL and adds automatically information about that URL under your post.
This plugin does it not automatically, you have to use the extra button in the visual editor (“URL BOX”). 
Or you just write [urlpreviewbox url=”\https://….”] into your text. 
This plugin loads information about that URL from https://guteurls.de/ server.
<ol>
<li>Title of that page</li>
<li>Description of that page</li>
<li>An URL of an image</li>
</ol>
And the plugin displays it below your post.
Facebook supports only one preview box per post. 
This plugin supports many preview boxes within one post, if you want.
Do you want to see it live on production servers?

<li>Copy “gurlpb-en.pot” to “gurlpb-LANG_COUNTRY.pot” – fill in LANG and COUNTRY with whatever you use for WPLANG in wp-config.php</li>
<li>Grab a transalation editor. <a href="http://www.poedit.net/" rel="nofollow ugc">POedit</a> works for us</li>
<li>Translate each line</li>
</ol>

URL-Preview-Box

That was really needed, because the automatic URL detection failed sometimes at very different designed WordPress templates.
This is the WordPress plugin, what I exactly needed. 
I use it now and will use it in the next years for sure.

Now it is possible to add manually preview boxes

This plugin adds link preview box to your post. You just copied & pasted an URL into your posting. :-)
