Can it convert existing camelCase or snake_case input?

Yes. The converter splits on spaces, punctuation, underscores, hyphens and camelCase boundaries, so you can paste an identifier in any style and reformat it.

Is my text uploaded anywhere?

No. The conversion runs entirely in your browser with JavaScript — nothing is sent to a server and nothing is stored.

What is the difference between camelCase and PascalCase?

Both join words with no separator and capitalise each word, but camelCase keeps the first word lowercase (e.g. userName) while PascalCase capitalises it too (e.g. UserName). camelCase is common for variables and functions; PascalCase for classes, types and React components.

When should I use snake_case versus kebab-case?

snake_case (words joined by underscores) is the convention for Python, Ruby and database column names. kebab-case (words joined by hyphens) is used for URLs, CSS class names and HTML attributes. CONSTANT_CASE is reserved for fixed values like environment variables.

How does Title Case differ from Sentence case?

Title Case capitalises the first letter of every word (Convert Your Text Now). Sentence case capitalises only the first letter of the whole string (Convert your text now). This tool produces both at once so you can pick the right one for a heading versus body copy.

Will it fix an all-caps phrase typed by accident?

Yes. Paste a sentence that is stuck in CAPS LOCK and the Sentence case, lower case and Title Case outputs all give you a corrected version instantly, ready to copy back.

Case Converter — Gera Tools

Convert text between every case

This tool reformats any text, identifier or phrase into nine cases at once — camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, Title Case, Sentence case, lower case and UPPER CASE. It is built for developers renaming variables between language conventions, writers fixing capitalisation, and anyone converting a heading into a URL-ready or code-ready form without retyping it.

How it works

Your input is first tokenised into words. The converter inserts a boundary between a lowercase letter and an uppercase one (so userName splits into user and Name), then splits on every non-alphanumeric character — spaces, hyphens, underscores and punctuation. Because of this, you can paste an identifier in any existing style and reformat it into another. Each case then rejoins those words with its own separator and capitalisation rule.

Example

Paste getUserProfile-data and you get every form at once:

Case	Output
camelCase	getUserProfileData
PascalCase	GetUserProfileData
snake_case	get_user_profile_data
CONSTANT_CASE	GET_USER_PROFILE_DATA
kebab-case	get-user-profile-data
Title Case	Get User Profile Data
Sentence case	Get user profile data

Click Copy next to whichever one you need. Every conversion happens in your browser; nothing is uploaded.
