Case Converter — camelCase, snake_case,

Case Converter

This example demonstrates case conversion from String Tools, pre-loaded with a sample phrase converting to camelCase. Paste any text and convert it between standard programming case formats.

Supported Case Formats

Format	Example	Use Case
UPPERCASE	HELLO WORLD	Constants, shouts
lowercase	hello world	General text
Title Case	Hello World	Headings, titles
camelCase	helloWorld	JavaScript variables, CSS properties
PascalCase	HelloWorld	Class names, React components
snake_case	hello_world	Python variables, database columns
kebab-case	hello-world	CSS classes, URLs, CLI flags
dot.case	hello.world	Namespaces, config paths

How Case Conversion Works

The tool first normalizes the input by splitting it into words. It handles multiple delimiters: spaces, underscores, hyphens, and case transitions (like the uppercase W in helloWorld). Once split, each word is reformatted according to the target case.

camelCase and PascalCase Nuances

camelCase lowercases the first word and capitalizes subsequent words: myVariableName. PascalCase capitalizes every word: MyVariableName. When converting from snake_case or kebab-case, each segment becomes a word. When converting from UPPERCASE or lowercase, the tool splits on spaces and capitalizes accordingly.

Converting Between Programming Languages

Different languages use different conventions. Python uses snake_case for functions and PascalCase for classes. JavaScript uses camelCase for functions and variables. When porting code between languages, converting identifiers between cases is a common task.

How to Use

1. Paste your text into the input area
2. Select the target case format from the options
3. The converted output appears instantly
4. Copy the result using the copy button

Common Questions

Does the converter handle acronyms correctly?

The tool treats acronyms as single words when possible. For example, converting parse XML data to camelCase produces parseXmlData, where XML is treated as one word. Converting to UPPERCASE produces PARSE XML DATA.

Can I convert a single word?

Yes. Single words work fine. hello in UPPERCASE becomes HELLO. In Title Case becomes Hello. In camelCase stays hello (no subsequent words to capitalize).

What about non-English text?

The tool handles ASCII word boundaries (spaces, underscores, hyphens, case changes). Non-Latin scripts without these delimiters may not split as expected. For scripts that do not use spaces between words, manual splitting may be necessary.
