ChangeCase is a small tool designed to change the case (lowercase/uppercase) of text. It is available as an add-on for the Chrome platform and is developed by konstantinsmetana. This tool is completely free to use and falls under the category of Browsers, specifically under the subcategory of Add-ons & Tools.

ChangeCase offers several useful features for manipulating text case. Users can easily convert lowercase text to uppercase, or vice versa. Additionally, there is a "Convertcase" option that allows for more advanced case conversions. Another handy feature is the ability to convert a string into a slug format.

To make the usage of ChangeCase even more convenient, it provides shortcuts for quick case conversions. Pressing "Ctrl+Shift+U" will convert the selected text to uppercase, "Ctrl+Shift+L" will convert it to lowercase, and "Ctrl+Shift+Z" will perform a convert operation.

To use ChangeCase, simply select the desired text, right-click, and choose the appropriate option from the context menu. Alternatively, you can use the provided keyboard shortcuts for faster conversions.
