What Is a Text Case Converter?
A text case converter is a tool that changes the capitalization of your text. Whether you accidentally typed an entire essay in CAPS LOCK, need to format a title properly, or want to convert variable names between programming conventions, this tool does it instantly.
This converter supports 12 different text cases organized into three categories: common text cases (UPPERCASE, lowercase, Title Case, Sentence case), programming cases (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case), and fun cases (aLtErNaTiNg, iNVERSE). Each conversion updates in real-time as you type.
When to Use Each Text Case
UPPERCASE
Used for headings, acronyms, emphasis, and constants. Common in legal documents and signage.
lowercase
Standard for body text, email addresses, URLs, and database fields. Used when you need to normalize text.
Title Case
Capitalizes major words. Used for book titles, article headlines, and proper nouns. Follows AP style guidelines.
Sentence case
Capitalizes only the first word of each sentence. Natural for paragraphs, descriptions, and UI text.
camelCase / PascalCase
camelCase for JavaScript variables/functions. PascalCase for class names and React components.
snake_case / kebab-case
snake_case for Python variables and database columns. kebab-case for CSS classes and URL slugs.

Frequently Asked Questions
What is Title Case and how does it work?
Title Case capitalizes the first letter of each major word while keeping minor words (a, an, the, and, but, or, for, in, of, etc.) lowercase. The first word is always capitalized. For example, "the lord of the rings" becomes "The Lord of the Rings." This follows AP Stylebook guidelines used by most publications.
What's the difference between camelCase and PascalCase?
Both join words together and capitalize each word's first letter, but camelCase starts with a lowercase letter (e.g., myVariableName) while PascalCase starts with an uppercase letter (e.g., MyClassName). In JavaScript and TypeScript, camelCase is standard for variables and functions, while PascalCase is used for classes and React components.
Can I convert text while typing?
Yes! Once you select a case conversion, the output updates in real-time as you type or edit your input text. This makes it easy to preview how your text will look in different cases without clicking the button again.
