Change Titles Case


This plugin is completely free, and offers no pro versions. Custom Website and WordPress Plugin Assistance is available.

Please visit my website for screenshots and more.

I created this plugin with the desire to help convert titles or transform titles case to various case styles on posts and categories. Initially this was for handling issues due to importing improper cased data but I soon realized many people needed this.

The transform case plugin works by modifying the titles and provides certain advantages over CSS solutions by providing advanced control and customization.

Currently, the plugin supports Upper, Lower, and Mixed/Snake Case. Sentence case is desired, but currently not supported due to the need for a list of nouns. It should work with all latin languages, but is not currently language specific in its design.

This plugin allows you to set words/acronyms that will keep these key words lower or upper case. This can allow you to change the case frequently.

Since this plugin runs from the Admin screen. There is no requirement to keep this plugin after its transformation is performed, and it should not degrade the performance of your server.

No warranty is provided and we recommend backing up the system before performing any transformation. Use at your own risk.

What is the future possibility’s for this plugin

I’d love to add sentence case and also add an option to automatically format the title when the document is first inserted as well as updated. Please contact me if you’d like to rush the process by paying me for my time.

Have been waiting for a plugin EXACTLY like this for quite literally…YEARS! Does the job perfectly – flawless and super quick too. Changed just over 20000 posts with Capitalized titles to Title Case. Thank you!!

Why didn’t someone make this sooner? This is brilliantly thoughtful with consideration for acronyms and various cases. I’m shocked to see that there are not more people using this plugin. I would think the most major publishers would be interested in this.
