About the Code Case Converter

The ByteTools Code Case Converter takes any identifier — however it is currently written — and shows it in every common programming case at once: camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case and Title Case. Instead of picking a target format, you see them all and copy the one you need.

It splits your input intelligently on spaces, underscores, hyphens, dots and camelCase humps, and it keeps runs of capitals sensible, so a value like userID or XMLHttpRequest breaks into words the way you would expect. That makes it ideal for renaming variables, database columns, CSS classes, env vars and API fields consistently.

Conversion runs 100% locally in your browser. Nothing you type is uploaded, logged or stored, so it is safe for internal field names and unreleased code, and it works offline.

Frequently asked questions

What is the difference between camelCase and PascalCase?

Both join words without separators, but camelCase lowercases the first letter (myVariableName) while PascalCase capitalizes it (MyVariableName). camelCase is common for variables and functions in many languages; PascalCase is typical for classes, types and components.

What is snake_case versus kebab-case?

snake_case joins lowercase words with underscores (user_id) and is common in Python, Ruby and database columns. kebab-case joins lowercase words with hyphens (user-id) and is common in URLs, CSS class names and file names. This tool shows both from the same input.

How does the converter split my identifier into words?

It breaks on spaces, underscores, hyphens and dots, and also on camelCase boundaries — the point where a lowercase letter meets an uppercase one. Runs of capitals followed by a normal word, like in XMLParser, are split into XML and Parser so acronyms stay intact.

What is CONSTANT_CASE used for?

CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) writes words in uppercase joined by underscores, like MAX_RETRY_COUNT. It is the conventional style for constants and environment variables in many languages, signalling a value that should not change.

Is my input uploaded when I convert it?

No. All conversion happens in your browser with JavaScript. The identifier you enter is never transmitted, logged or stored, so it is safe to use with internal names and proprietary code.
