Case Converter

Text case conversion is the process of changing the capitalization pattern of text to different formats. Common cases include uppercase, lowercase, title case, sentence case, and specialized programming formats like camelCase and snake_case.

Each case format serves specific purposes: title case for headings, sentence case for regular writing, camelCase for variables in programming, and UPPERCASE for emphasis or constants.

// Original text:
hello world example text

// Different case formats:
Sentence case: Hello world example text
Title Case: Hello World Example Text
UPPERCASE: HELLO WORLD EXAMPLE TEXT
lowercase: hello world example text
camelCase: helloWorldExampleText
PascalCase: HelloWorldExampleText
snake_case: hello_world_example_text

Case conversion is essential for formatting content, writing code, preparing documents, and ensuring consistency across different platforms and applications.
