Text Case Converter
camelCase, snake_case & More
Convert text into camelCase, PascalCase, snake_case, kebab-case, UPPER CASE, lower case, Title Case, and Sentence case.
What is this tool?
This text case converter transforms words into common naming styles: camelCase, PascalCase, snake_case, kebab-case, UPPER CASE, lower case, Title Case, and Sentence case.
The converter splits input on whitespace, hyphens, underscores, punctuation cleanup, and capital-letter boundaries. That makes it useful for moving between human-facing labels and code-facing identifiers, but it can also normalize acronyms more aggressively than a human editor would.
Use it during refactors, schema design, CSS naming, file naming, API field mapping, documentation cleanup, and translation preparation.
How to use
- Paste a phrase, heading, variable name, or identifier.
- Review the generated case variants.
- Copy the variant that matches your codebase, URL, file name, or editorial style.
- Manually check acronyms and brand terms because automated casing may normalize them.
Examples
| Input / setting | Output | Notes |
|---|---|---|
hello world | camelCase helloWorld; PascalCase HelloWorld; snake_case hello_world; kebab-case hello-world | Common developer naming formats. |
api response id | camelCase apiResponseId; snake_case api_response_id | Lowercase words converted into identifier styles. |
