Frequently Asked Questions

What case formats are supported?

The tool supports 14 different case formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, dot.case, CONSTANT_CASE, path/case, aLtErNaTiNg CaSe, iNVERSE cASE, and RaNdOm CaSe.

What's the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter (firstName), while PascalCase starts with an uppercase letter (FirstName). PascalCase is also called UpperCamelCase and is commonly used for class names.

When should I use snake_case vs kebab-case?

snake_case is commonly used in Python, database fields, and environment variables. kebab-case is preferred for CSS classes, URLs, file names, and HTML attributes because it's more web-friendly.

Can I preserve special characters and formatting?

Yes! Enable 'Preserve Special Characters' to maintain punctuation, numbers, and special symbols while only converting the letter cases.

What does 'Process Line by Line' do?

This option treats each line as a separate text unit, which is useful when converting multiple items like a list of variable names or sentences that should be processed independently.
