Question 1

What is text case conversion?

Accepted Answer

Text case conversion transforms the capitalisation pattern of a string without changing its words. Common uses include converting prose to programming identifiers (snake_case, camelCase), formatting titles (Title Case), or standardising user input. This tool handles all 12 common case formats simultaneously.

Question 2

What is the difference between camelCase and PascalCase?

Accepted Answer

Both join words without spaces, but camelCase starts with a lowercase letter (helloWorld) while PascalCase (also called UpperCamelCase) starts with an uppercase letter (HelloWorld). camelCase is commonly used for variables and function names in JavaScript/Java. PascalCase is used for class names, components (React), and types in most languages.

Question 3

When should I use snake_case vs kebab-case?

Accepted Answer

snake_case (words joined by underscores) is the convention for variable names in Python, Ruby, and SQL column names. kebab-case (words joined by hyphens) is used for URLs, CSS class names, HTML attributes, and file names. Neither is universally better — the right choice depends on the context and language convention.

Question 4

Can this converter handle camelCase or PascalCase as input?

Accepted Answer

Yes. The converter intelligently splits camelCase and PascalCase input at word boundaries before converting. For example, "helloWorldExample" is correctly split into ["hello", "world", "example"] before being converted to any target format. It also handles underscores, hyphens, and spaces as word separators.

Question 5

What is CONSTANT_CASE and where is it used?

Accepted Answer

CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) writes all words in uppercase joined by underscores, like MAX_RETRY_COUNT. It is the standard convention for constants in Python, Java, JavaScript, and C++, as well as for environment variables (API_KEY, DATABASE_URL). The visual distinction from regular snake_case makes constants immediately recognisable.

Question 6

Is my text sent to a server when I convert it?

Accepted Answer

No. All conversion logic runs entirely in your browser using JavaScript. Your text never leaves your device. This makes the tool safe for converting sensitive content like API keys, passwords, or private documents.
