Convert Case

Convert Case refers to the process of changing the capitalization style of a text string. It is a common feature in programming, text processing, and web applications to make text consistent, readable, or suitable for specific uses like URLs, class names, or user interfaces.

Why Convert Case?

• Consistency: Ensure all text follows a uniform format.

• Readability: Make text easier to read for users.

• Data processing: Normalize text before saving in databases or performing searches.

• Programming conventions: Follow coding standards, like camelCase for variables or StudlyCase for classes.

Common Case Types

1. Lowercase
   Converts all letters to lowercase.
   Example: "Hello World" → "hello world"

2. Uppercase
   Converts all letters to uppercase.
   Example: "Hello World" → "HELLO WORLD"

3. Capitalized / Title Case
   Capitalizes the first letter of each word.
   Example: "hello world" → "Hello World"

4. Sentence Case
   Capitalizes only the first letter of the sentence; the rest is lowercase.
   Example: "hELLO WORLD!" → "Hello world!"

5. Camel Case
   The first word is lowercase, and each following word starts with an uppercase letter. Common in variable names.
   Example: "hello world" → "helloWorld"

6. Studly / Pascal Case
   Each word starts with an uppercase letter. Common for class names.
   Example: "hello world" → "HelloWorld"

7. Snake Case
   Words are lowercase and separated by underscores. Common in database columns.
   Example: "Hello World" → "hello_world"

8. Kebab Case
   Words are lowercase and separated by hyphens. Common in URLs.
   Example: "Hello World" → "hello-world"

9. Alternating Case
   Letters alternate between lowercase and uppercase.
   Example: "hello world" → "hElLo WoRlD"

10. Inverse / Swap Case
    Uppercase letters become lowercase, and lowercase letters become uppercase.
    Example: "Hello World" → "hELLO wORLD"
