How to Use the Variable Case Converter

Naming things is notoriously one of the two hardest problems in computer science (along with cache invalidation). But formatting those names shouldn’t be hard. The ToolsHref Case Converter helps you instantly switch between different programming syntax styles without manually retyping every character.

Step-by-Step Guide

  1. Enter your Text: Type or paste any text into the main input box. This can be:
    • A normal sentence: “Get user by id”
    • An existing variable: “get_user_by_id”
    • Mixed formatting: “getUser-ByID”
  2. View Instantly: As you type, the tool automatically parses your input, splits it into logical words, and regenerates it into all 6 major naming conventions simultaneously.
  3. One-Click Copy: Click the “Copy” button next to the specific format you need (e.g., camelCase for Java, snake_case for Python).

Pro Tip: Click the “✨ Load Sample” button to see a quick demonstration of how the tool handles mixed casing and spaces.

Variable Naming Conventions Explained

Different programming languages enforce different style guides. Using the wrong casing isn’t just a stylistic error; in case-sensitive languages, it can break your code.

camelCase

The first letter is lowercase, and the first letter of every subsequent word is capitalized.

Example: myVariableName

Used in: JavaScript, Java, Swift, Kotlin (variables & functions).

snake_case

All letters are lowercase, separated by underscores.

Example: my_variable_name

Used in: Python, Ruby, Rust, SQL Database columns.

PascalCase

Also known as “UpperCamelCase”. Every word starts with a capital letter.

Example: MyVariableName

Used in: Classes (Java/C#), React Components, Interfaces.

kebab-case

All lowercase, separated by hyphens. Often called “Lisp Case”.

Example: my-variable-name

Used in: URLs (slugs), HTML attributes, CSS classes.

Frequently Asked Questions (FAQ)

Why does the tool add spaces when I type CamelCase?

Our intelligent parser detects when a capital letter appears in the middle of a word (e.g., “UserID”) and assumes it signifies a new word. This allows you to paste existing code variables and convert them cleanly without manually adding spaces first.

What is SCREAMING_SNAKE_CASE used for?

This format (labeled as CONSTANT_CASE in our tool) is universally used to define constants—values that should not change during the execution of the program. For example, MAX_RETRY_COUNT or API_BASE_URL.

Is this useful for non-programmers?

Yes! Content creators and SEO specialists use this tool to generate kebab-case URLs. If you have a blog post titled “Top 10 Tools for 2025”, you can paste that title here to instantly get the URL-friendly slug: top-10-tools-for-2025.
