How to switch text case in visual studio code

In Visual Studio Code (VSCode), you can easily toggle the case of text, which is very useful for quickly adjusting text formatting when programming or editing documents. Below are the steps to do this:

1. Select Text: First, select the text you want to change the case of using your mouse or keyboard.

2. Open Command Palette: Open the Command Palette using the shortcut Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (Mac).

3. Input Command: In the Command Palette, type "transform" to filter relevant commands. You will see several options, including:

   • Transform to Uppercase: Converts the selected text to uppercase.
   • Transform to Lowercase: Converts the selected text to lowercase.

4. Select and Apply: Click the command you need, for example, if you want to convert the text to uppercase, select Transform to Uppercase. The selected text will be converted to uppercase immediately.

Example: Suppose you are editing a JavaScript file containing the following:

javascript
let message = "hello world";

You want to convert the ""hello world"" part to uppercase. Select ""hello world"", open the Command Palette, type "transform", and then choose Transform to Uppercase. After that, the code becomes:

javascript
let message = "HELLO WORLD";

This feature is very useful when dealing with code or documents that require specific case rules. For instance, in programming, constants are commonly named in all uppercase, and using this feature enables quick formatting changes, enhancing productivity.
