Frequently Asked Questions

What is camelCase? +

camelCase writes compound words without spaces, capitalizing the first letter of each word except the first: "myVariableName". It is widely used in JavaScript, Java, and Swift for variable and function names.

What is the difference between snake_case and kebab-case? +

Both separate words with a delimiter in lowercase. snake_case uses underscores (my_variable) and is common in Python and databases. kebab-case uses hyphens (my-variable) and is common in CSS class names and URLs.

What is PascalCase used for? +

PascalCase capitalizes the first letter of every word with no separator: "MyClassName". It is the standard for class names in most object-oriented languages including JavaScript, C#, Java, and PHP.

Can I convert sentences and paragraphs? +

Yes. The tool intelligently splits on spaces, underscores, hyphens, dots, and camelCase/PascalCase boundaries — so any format works as input. Multi-line text and sentences are fully supported.

Is my text sent to a server? +

No. All conversions happen instantly in your browser using JavaScript. Your text never leaves your device.
