Frequently Asked Questions
What text cases does this tool support?
This tool supports 12 text case conversions: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, Alternating cAsE, and Inverse cASE.
What is the difference between camelCase and PascalCase?
In camelCase the first word starts with a lowercase letter and each subsequent word is capitalised (e.g. myVariableName). In PascalCase every word — including the first — starts with a capital letter (e.g. MyVariableName). Both remove spaces between words.
When should I use snake_case vs kebab-case?
snake_case (words_separated_by_underscores) is common in Python, Ruby and database column names. kebab-case (words-separated-by-hyphens) is widely used in URLs, CSS class names and HTML attributes.
Is my text sent to a server?
No. All conversions happen entirely in your browser using JavaScript. Your text never leaves your device, so it is completely private and secure.
Is there a character limit?
There is no hard limit. Because the conversion runs locally in your browser, it can handle very large texts without any noticeable delay.
