Case converter
Convert text between UPPER, lower, camelCase, and more.
Questions
What does this tool do?
The Case converter rewrites any text or identifier into nine cases at once: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. Paste a phrase or a variable name and every style renders live, each with its own copy button. Words are split on spaces, punctuation and camelCase boundaries, and acronyms stay intact: HTMLParser becomes HTML_PARSER, not H_T_M_L_PARSER.
How are acronyms handled?
Words are split on whitespace, punctuation and case boundaries. HTMLParser becomes HTML and Parser, so the acronym stays intact in CONSTANT_CASE.
Sentence case or Title Case?
Sentence case lower-cases everything and capitalises the first letter — for prose. Title Case capitalises each word — for headlines.
