If you’re wanting an easy way to quickly convert posts written in the Classic Editor into Blocks without having to edit each post and change them individually, check out this brand new WordPress plugin created by Marie Comet. Once installed and activated, you’ll find a Classic to Gutenberg link located in the Tools menu.
This plugin adds a user interface that enables you to see a list of Posts or Pages that have been published in the Classic Editor, Gutenberg, or both. Simply check the box next to the post you want to Convert and click the Convert button.
In my limited testing, I published two posts. One contained nothing but paragraphs while the other contained paragraphs and ordered lists. In both cases, the converted posts took successive paragraphs and bunched them together into one paragraph block. Meanwhile, the ordered lists were correctly converted into their block counterparts in the correct locations. Here is an example of what I’m talking about.
I believe the goal of this plugin is to provide a convenient option to convert old content into blocks without having to open up each post and convert them individually. However, if paragraphs are converted into giant blocks of text, it defeats the purpose and whatever time savings is generated is then removed. This plugin is brand new and needs to undergo further testing but the first major issue that needs to be addressed is paragraph conversion as it’s likely the most used block in WordPress.
If you decide to try this plugin out for yourself, Comet advises people to backup their database before applying any changes to a live site. Comet is open to feedback from the community about the experimental plugin and Pull Requests are welcomed. What would you like to see in a Classic Post to Block conversion tool?
