Frequently asked questions
What's the difference between camelCase and PascalCase?+
camelCase starts with a lowercase letter (myVariableName), while PascalCase starts with an uppercase letter (MyVariableName). camelCase is common for variables and functions; PascalCase is common for class and component names.
When would I use snake_case vs kebab-case?+
snake_case (with underscores) is the convention in Python and many database column names; kebab-case (with hyphens) is common in URLs, CSS class names, and HTML attributes, since underscores aren't always URL-friendly.
How does the tool detect word boundaries in my input?+
It splits on spaces, hyphens, underscores, and transitions from lowercase to uppercase letters, so it can correctly reformat text that's already in camelCase or snake_case into another format.
Does Sentence case only capitalize the first word?+
It capitalizes the first letter after the start of the text and after sentence-ending punctuation (. ! ?), similar to how a word processor's 'Sentence case' option works, leaving the rest lowercase.
Can I convert a whole paragraph, not just a single word?+
Yes, the input accepts multi-word text and even multiple sentences; each case format is applied to the entire input, not word by word individually.
Is my text stored or sent anywhere?+
No, all nine conversions run instantly and entirely in your browser as you type — nothing is transmitted to a server.
