Frequently Asked Questions

What's the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter and capitalizes subsequent words without spaces (e.g., "myVariableName"). PascalCase capitalizes the first letter of every word including the first (e.g., "MyClassName"). camelCase is common for variables/functions in JavaScript, while PascalCase is used for classes and components.

When should I use snake_case vs kebab-case?

snake_case uses underscores between words (e.g., "user_profile_data") and is standard in Python, Ruby, and SQL databases. kebab-case uses hyphens (e.g., "user-profile-data") and is common in URLs, CSS class names, and command-line flags. Both are lowercase throughout.

What is Title Case and how does it work?

Title Case capitalizes the first letter of each word while lowercasing the rest (e.g., "This Is Title Case"). Our tool capitalizes all words for simplicity. Note that formal Title Case has complex rules about capitalizing articles (a, an, the) and prepositions, which vary by style guide.

Can this tool convert text with special characters?

Yes, but special characters are handled differently by each case type. For developer cases (camel, Pascal, snake, kebab), special characters are typically replaced with separators or removed. For text cases (UPPER, lower, Title), special characters are preserved but not modified.

Does Sentence case capitalize after every period?

Yes, our Sentence case converter capitalizes the first letter of the text and the first letter after each period (.), exclamation mark (!), or question mark (?). Everything else is lowercased. This mimics proper sentence capitalization rules.

What happens to numbers in the converted text?

Numbers are preserved in all case conversions since they don't have case. In developer cases (camel, Pascal, snake, kebab), numbers are treated as part of words. For example, "user123data" becomes "user123Data" in camelCase or "user-123-data" in kebab-case.

Can I convert multiple paragraphs at once?

Yes! Our tool handles text of any length including multiple paragraphs, sentences, and line breaks. All 8 case types will convert your entire text while preserving paragraph structure (except developer cases which remove spaces).

Is there a character limit for conversion?

There's no hard character limit. The tool can handle very large texts efficiently since conversion happens entirely in your browser. However, extremely large texts (100,000+ characters) may cause slight delays depending on your device performance.
