Case Converter

Overview

• Converts the text you enter into all 9 naming conventions at once, including camelCase, PascalCase, snake_case, and kebab-case.
• Recognizes underscores, hyphens, and spaces, as well as camelCase uppercase boundaries, as word separators, so it works regardless of the input format.
• Useful when you want to unify variable names, function names, file names, and other identifiers to match a project's naming conventions.

Usage

1. Enter the text you want to convert into the text area (any format such as user_name, UserName, or user name works).
2. Click the "Convert" button.
3. The result is displayed, converted into all 9 naming conventions including camelCase, PascalCase, and snake_case.

Example

user_name

camelCase: userName
PascalCase: UserName
snake_case: user_name
kebab-case: user-name

Use Cases

• Converting between API property names (snake_case) and in-code variable names (camelCase) when integrating with another language or framework
• Converting a label text received from a designer into PascalCase or CONSTANT_CASE for use as a variable or constant name
• Converting names in existing code that mix several formats into the naming convention your project uses

FAQ

Notes

• Intended for use with alphanumeric text. Japanese text may not convert as expected, since word boundaries cannot be reliably detected.
• The conversion result exists only on the page and is lost on reload, so copy and save it if you need to keep it.
• Consecutive uppercase letters (e.g. XMLHttpRequest) may be split differently than intended, depending on the word-boundary detection rules.
