About the Text Case Converter
Retyping text to fix its capitalization — after accidentally leaving caps lock on, formatting a headline, or preparing a variable name for code — is a small but constant annoyance. Writers, students, and developers all reach for case conversion regularly, each needing a different case style for a different purpose.
This tool converts the same text into six common formats at the click of a button: uppercase, lowercase, title case (for headlines), sentence case (for standard prose), camelCase, and snake_case (both common in programming variable naming).
Frequently Asked Questions
What's the difference between title case and sentence case?
Title case capitalizes the first letter of most words (commonly used for headlines and titles), while sentence case only capitalizes the first letter of each sentence, matching normal prose writing.
What are camelCase and snake_case used for?
Both are naming conventions used in programming for variable and function names. camelCase capitalizes the first letter of each word except the first (e.g., firstName), while snake_case separates words with underscores in all lowercase (e.g., first_name).
Does title case capitalize every word?
This tool follows common title case convention, which typically lowercases short connector words like "a," "the," "and," and "of" unless they're the first or last word — matching standard editorial style guides.
