Frequently Asked Questions — Case Converter
What is the difference between title case and sentence case?
Title case capitalizes the first letter of every major word, typically lowercasing articles and prepositions like "the," "and," and "of." Sentence case only capitalizes the first letter of each sentence, matching normal writing style.
Can I convert programming variable names?
Yes. The tool supports camelCase where the first word is lowercase and subsequent words are capitalized, PascalCase where every word starts uppercase, and snake_case where words are joined with underscores. These are commonly used in programming.
Does title case handle small words correctly?
Yes. The tool follows standard English title capitalization rules, keeping words like "a," "an," "the," "and," "but," "or," "in," "on," and "at" in lowercase unless they are the first or last word of the title.
