What is camelCase and when should I use it?

camelCase is a naming convention where compound words or phrases are joined without spaces, the first letter of the entire identifier is lowercase, and the first letter of each subsequent word is capitalized (e.g., 'getUserAccount'). It is the standard identifier convention in JavaScript, TypeScript, Java, and C#.

What is the difference between snake_case and kebab-case?

snake_case separates words with underscores (e.g., 'user_id') and is the preferred standard in Python (PEP 8), Ruby, and relational database table column naming. kebab-case separates words with hyphens (e.g., 'user-id') and is standard in URL slugs, REST endpoints, and CSS class names.

What is PascalCase / UpperCamelCase?

PascalCase capitalizes the first letter of every word, including the first word (e.g., 'UserProfileComponent'). In programming, it is universally used for class names, React components, TypeScript interfaces, and enum types.

How does Title Case capitalization handle prepositions and articles?

In English style guides (Chicago, APA, MLA), Title Case capitalizes the first and last words, all major words (nouns, verbs, adjectives, adverbs), and keeps minor words (articles 'a, an, the', short conjunctions 'and, but, or', and short prepositions 'in, on, at, to') lowercase unless they begin the title.

Is my text data stored or sent to any server when converting case?

No. All string parsing, regex transformations, and case conversions execute 100% locally within your client browser runtime. No text or code is ever transmitted to remote servers.

Text Case Converter

Convert text and code variables between camelCase, snake_case, kebab-case, PascalCase, CONSTANT_CASE, and Title Case in real time.

Quick Answer & Summary

A Text Case Converter automatically normalizes and translates strings between different letter casing formats (e.g. converting 'hello world' into camelCase 'helloWorld', snake_case 'hello_world', or kebab-case 'hello-world') for code variables, database schemas, and editorial headlines.

Programming Case Formatting Rules

camelCase: [a-z]+([A-Z][a-z]+)* | snake_case: [a-z]+(_[a-z]+)* | kebab-case: [a-z]+(-[a-z]+)*

Words are delimited by whitespace, underscores, or hyphens, then projected into the target naming convention.
