About this tool
One click converts your text to any casing, including programmer variants like camelCase, PascalCase, snake_case and kebab-case. Sentence-case boundaries are detected from punctuation, not just periods, so abbreviations do not wreck the result.
Your input never leaves the browser: this tool works entirely offline once the page has loaded.
Frequently asked questions
How does camelCase detection work?
Boundaries are detected from uppercase runs and non-alphanumeric separators, so myVariableName becomes "my variable name" and XMLHttpRequest becomes "xml http request".
Does Sentence case handle abbreviations?
It lowercases everything and capitalizes after sentence-ending punctuation — abbreviations like "U.S." become lowercase, so review the result if your text contains many of them.
