FAQ

What is the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (e.g. myVariableName) while PascalCase capitalizes the first letter of every word including the first (e.g. MyVariableName).

What is CONSTANT_CASE used for?

CONSTANT_CASE (all uppercase with underscores) is commonly used for constant values in many programming languages, such as MAX_RETRY_COUNT.

Does this tool handle multiple words and punctuation correctly?

Yes, the converter splits on spaces, hyphens, underscores and camelCase boundaries to correctly identify word boundaries before reformatting.

Is my text uploaded anywhere?

No. All conversions happen instantly and locally in your browser using JavaScript.

Is there a character limit?

No practical limit — the tool handles large blocks of text (well over 1MB) smoothly since everything runs client-side.
