When to use each format

UPPERCASE: Headings, acronyms, button labels, warnings, and any text that needs strong visual emphasis. Avoid using for long passages as it reduces readability significantly.
lowercase: Casual writing, usernames, email addresses, and URLs. Also used in certain brand identity systems for a modern aesthetic.
Title Case: Article titles, book titles, movie names, headings, and proper nouns. Title case capitalizes the first letter of major words while keeping articles and prepositions lowercase.
Sentence case: Standard prose, emails, captions, and any flowing text. Capitalizes only the first word of each sentence and proper nouns.
camelCase: JavaScript and Java variable names, function names, and object properties. The first word is lowercase and each subsequent word starts with a capital letter.
PascalCase: Class names in object-oriented languages like Java, C#, and TypeScript. Similar to camelCase but the first word is also capitalized.
snake_case: Python variables, SQL column names, file names, and database fields. Words are lowercase and separated by underscores.
kebab-case: URL slugs, CSS class names, HTML attributes, and file names. Words are lowercase and separated by hyphens.
CONSTANT_CASE: Constants in programming languages like JavaScript, Java, and C++. All uppercase with underscores separating words.
aLtErNaTe: Alternating uppercase and lowercase characters. Used for stylistic or humorous effect in social media and memes.

Frequently asked questions

Does title case capitalize every word?

No. Title case follows standard rules that keep short prepositions, articles, and conjunctions lowercase unless they are the first or last word. Words like "a", "an", "the", "and", "but", "or", "in", "on", "at", and "to" stay lowercase in the middle of a title.

What is the difference between camelCase and PascalCase?

Both formats join words together without spaces and capitalize the first letter of each word except the first. The difference is that camelCase keeps the very first letter lowercase (myVariableName) while PascalCase capitalizes it (MyVariableName). PascalCase is also called UpperCamelCase.

Can I convert camelCase back to plain text?

Yes. If you paste camelCase or PascalCase text, the converter detects the capital letters and handles the splitting automatically when converting to other formats. This makes it easy to convert variable names to readable text for documentation.

Is there a character limit?

There is no enforced character limit. The converter handles documents of any length. All processing happens instantly in your browser — your text is never sent to any server.
