What is a text case converter and how does it work?

A text case converter is a tool that transforms text between different capitalization formats like uppercase, lowercase, title case, camelCase, and more. It uses JavaScript algorithms to instantly convert your text without sending data to servers, ensuring privacy and speed.

When should I use title case vs sentence case?

Title case is commonly used for headlines, book titles, article titles, and formal documents. It capitalizes the first letter of each major word while keeping articles, prepositions, and conjunctions in lowercase. Sentence case is used for normal sentences, captions, and descriptions where only the first letter is capitalized.

What's the difference between camelCase and PascalCase?

CamelCase starts with a lowercase letter and capitalizes subsequent words (e.g., 'myVariableName'), commonly used for JavaScript variables and functions. PascalCase capitalizes the first letter of every word including the first one (e.g., 'MyClassName'), typically used for classes and components.

Can I import and export text files?

Yes, our converter supports importing text files (TXT, CSV) and exporting converted results. This is perfect for bulk text processing, team collaboration, and integrating with other tools in your workflow.

Is my text data secure and private?

Yes, all text processing happens entirely in your browser using JavaScript. Your text is never sent to our servers, ensuring complete privacy and security of your data. The tool works offline once loaded.

What case formats are supported?

We support 9 case formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, kebab-case, snake_case, and aLtErNaTiNg CaSe. Each format serves different purposes in programming, writing, and content creation.
