What is Text Case Conversion?

Text case conversion is the process of changing the capitalization and formatting of letters in text. Different writing styles and programming languages require specific case formats for consistency, readability, and technical requirements.

Common Text Cases Explained

UPPERCASE • All letters are capitalized. Used for emphasis, headings, or acronyms.
lowercase • All letters are small. Common in programming and for normalizing data.
Title Case • The First Letter Of Each Word Is Capitalized. Ideal for book titles and headings.
Sentence case • Only the first letter of the sentence is capitalized. Used in regular text content.

💡 Different programming languages have conventions: JavaScript uses camelCase, Python prefers snake_case, while CSS uses kebab-case for property names.
