MRW Post Cleanup Utilities

v0.4.0

Mark Root-Wiley, MRW Web Design

A WordPress plugin with useful tools to transform blocks and post content for more accessible and consistent formatting.

[!TIP] I put a lot of unpaid work into a plugin like this. I publish it for free in hopes that it helps people save time and make better websites. If this plugin saved you time on a paid project, please consider sponsoring my work on the project or sponsoring work on a specific feature that would help you.

Features

• Detect fake headings and convert to real heading blocks at a selected level
• Set all heading blocks to one level
• Promote all heading blocks "up" a level in the hiearchy (e.g. H3 to H2)
• Strip all underline styles from the post
• Remove all "hard" linebreaks (the <br> tag)
• Replace all non-breaking spaces ( ) with regular spaces
• Convert selected blocks to Title Case or Sentence case

Installation

Upload the plugin zip or use wp-cli:

wp plugin install https://github.com/mrwweb/mrw-post-cleanup-utilities/archive/master.zip --force --activate

FAQs

Where are the utilities?

All utilities are in a custom block editor sidebar. To open it, click the wrench icon in the top-right corner of the block editor in the same row of buttons as the "Publish" button.

Where did the sidebar go? / Help, I lost the sidebar!

It's possible to remove the wrench icon by clicking the star icon in the top-right corner of the sidebar (next to the "X" close icon). If you do this, you'll find the sidebar in the triple-dot/kebab menu (next to the "Publish" button) under "Plugins".

Can you add "X" feature?

Maybe! See the existing list of issues. You can help by leaving a comment or reaction on an existing issue, opening a new one, or even sponsoring work on a feature you care about.
