How to use

1. **Enter Text**: Type or paste your text into the input text area.

2. **Select Case**: Choose one of four options:

   – **All Upper Case**: Converts text to uppercase (e.g., “hello world” → “HELLO WORLD”).

   – **All Lower Case**: Converts text to lowercase (e.g., “HELLO WORLD” → “hello world”).

   – **First Letter Upper Case**: Capitalizes the first letter, lowers the rest (e.g., “hello world” → “Hello world”).

   – **Title Case**: Capitalizes the first letter of each word (e.g., “hello world” → “Hello World”).

3. **Convert**: Click a case option to instantly see the converted text in the output text area.

4. **Copy or Clear**:

   – Click “Copy Text” to copy the converted text to your clipboard.

   – Click “Clear Text” to reset both input and output fields.

5. **Monitor Status**: Check the status bar for feedback (e.g., “Text copied to clipboard!” or “Enter text and select a case”).

Working Method

The Text Case Changer is a frontend-only tool built with HTML, CSS, and vanilla JavaScript, requiring no backend or API. Here’s how it works:

1. **Text Input**: Users enter text in a textarea.

2. **Case Selection**: Clicking a case option (e.g., “All Upper Case”) triggers JavaScript functions to transform the text using standard string methods (`toUpperCase`, `toLowerCase`, etc.).

3. **Conversion Logic**:

   – **Upper Case**: Uses `toUpperCase()` to convert all characters.

   – **Lower Case**: Uses `toLowerCase()` to convert all characters.

   – **Sentence Case**: Capitalizes the first character and lowers the rest.

   – **Title Case**: Splits text into words, capitalizes each word’s first letter, and joins them.

4. **Output Display**: The converted text is shown in a readonly text area.

5. **Copy Functionality**: Uses the `navigator.clipboard` API (in HTTPS contexts) or falls back to `document.execCommand(‘copy’)` to copy text to the clipboard.

6. **Clear Functionality**: Resets input/output fields and clears the selected case.
