What is a Text Case Converter?
A text case converter is a utility tool that transforms text from one case format to another. Case conversion is essential for maintaining consistent formatting across different contexts, from programming variable names to professional document titles. Instead of manually retyping text in different formats, this tool automates the process instantly.
The text case converter supports seven different case formats, each serving specific purposes in writing, coding, and data formatting. Whether you need to convert a sentence to title case for a headline or transform a phrase into camelCase for JavaScript variable naming, this tool handles all conversions seamlessly without altering the text content.

Case Conversion Types Explained
UPPERCASE & lowercase
Converting all characters to uppercase or lowercase. Used for acronyms, emphasis, and standardization.

Capitalizes the first letter of each word. Perfect for headlines, titles, and professional documents.
Sentence Case
Capitalizes only the first character. Ideal for standardizing text while maintaining readability.
camelCase

camelCase starts with a lowercase letter (myVariable), while PascalCase starts with uppercase (MyVariable). Our tool uses the proper camelCase format for programming conventions.
Can I convert multiple texts at once?
Our converter handles one text at a time, but you can use it repeatedly for multiple texts. Simply clear the input and paste your next text.
Are special characters and numbers preserved?
Yes, all special characters, numbers, and punctuation marks are preserved exactly as they are. Only letter casing is transformed.
Which format should I use for programming?
Use camelCase for JavaScript, Java, C#; snake_case for Python, SQL; UPPERCASE for constants; kebab-case for URLs and CSS classes.
Does this tool work offline?
Yes! All conversions occur in your browser locally. You don't need an internet connection after the page loads, though initially loading the page requires internet.
