The everyday cases
UPPERCASE and lowercase are the blunt instruments — headlines, fixing a paragraph typed with caps lock on, normalizing data before a comparison. Sentence case lowercases everything, then capitalizes the first letter of each sentence and the standalone word "I" — the fastest fix for text that arrived in all caps. Title Case capitalizes the significant words while keeping short joining words (a, an, the, of, to, and so on) lowercase, except when they begin or end the title — the convention most style guides use for headings.
The programmer cases
The remaining modes are identifier styles. camelCase (firstWordLower) and PascalCase (EveryWordUpper) are standard for variables and class names in JavaScript, Java, and C#. snake_case joins lowercase words with underscores — the Python and SQL convention. kebab-case joins with hyphens, the style of URLs and CSS classes. CONSTANT_CASE is snake_case shouted, used for constants and environment variables. The converter recognizes word boundaries from spaces, hyphens, underscores, and existing capital letters, so you can go from any of these styles to any other — paste userAccountId and get user_account_id back in one step.
Where this saves real time
Renaming a batch of variables between languages with different conventions. Turning a spreadsheet column of shouting-case product names into something presentable. Converting a document heading list into URL slugs. Fixing an email drafted in caps before anyone sees it. None of these are hard by hand — they're just tedious at any length, and tedious is what this page removes.
What Title Case does with edge cases
Title-case rules differ between style guides (AP, Chicago, MLA all disagree at the margins). This tool follows the common core: first and last words always capitalized, short conjunctions, articles, and prepositions lowercase in the middle. Words after punctuation keep their position-based rule. If your style guide has stricter opinions — say, capitalizing prepositions of four letters or more — give the result a quick read before publishing.
Frequently asked questions
Is the text I paste stored anywhere?
No. Conversion runs entirely in your browser. The page has no server to send text to, and nothing persists after you close the tab.
What's the difference between camelCase and PascalCase?
Only the first letter. camelCase starts lowercase (totalPageCount) and is the common style for variables and function names. PascalCase capitalizes every word including the first (TotalPageCount) and is typically used for class and type names.
Can it convert snake_case back to normal words?
Yes. The identifier modes treat underscores, hyphens, and capital-letter boundaries as word breaks, so first_day_of_month converts cleanly to Title Case as "First Day of Month", or to any other style.
