What is a Case Converter?

A text case converter is a versatile utility designed to change the capitalization and formatting of strings instantly. Whether you need to convert camelCase to snake_case, generate a clean URL slug, or format environment variables using CONSTANT_CASE, this tool handles the complexity of word boundaries and special characters automatically.

Common Naming Conventions Explained

Understanding different casing styles is crucial for clean code and effective SEO. Here is a breakdown of the formats supported by our online string converter:

  • camelCase: The first letter is lowercase, and each subsequent word starts with an uppercase letter (e.g., myVariable).
  • snake_case: All letters are lowercase, and words are separated by underscores (e.g., my_variable). Preferred for database columns.
  • CONSTANT_CASE: All letters are uppercase, and words are separated by underscores (e.g., MY_CONSTANT). Standard for environment variables.
  • kebab-case: Words are lowercase and separated by hyphens (e.g., my-variable). Standard for CSS classes.
  • dot.case: Words are separated by dots (e.g., my.variable). Often used in configuration keys.
  • PascalCase: Every word, including the first, starts with an uppercase letter (e.g., MyVariable). Standard for classes.
  • Sentence case: Only the first letter of the entire string is capitalized (e.g., My variable example).
  • URL Slug: A specific format that removes special characters and replaces spaces with hyphens to create SEO-friendly URLs.

How do I convert camelCase to snake_case?

Simply paste your camelCase string into the input field and click the "snake_case" button. The converter detects uppercase boundaries and inserts underscores automatically.

What is CONSTANT_CASE used for?

CONSTANT_CASE (also known as SCREAMING_SNAKE_CASE) is primarily used in programming for global constants, environment variables, and configuration settings.
