What is a Text Case Converter?

A text case converter is a tool that transforms text between different letter casing styles. Whether you need to change text to UPPERCASE for a headline, convert a variable name from camelCase to snake_case, or quickly capitalize a sentence, a case converter does the job instantly without manual editing.

CodeHelper's Text Case Converter supports 15+ case transformations including programming-specific formats like camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE.

Supported Case Formats

  • UPPERCASE / lowercase: The classic all-caps or all-lowercase transformations.
  • Title Case: Capitalizes the first letter of each word: great for headings.
  • Sentence case: Capitalizes only the first word of a sentence.
  • camelCase: Joins words with no separator, capitalizing each word after the first. Used in JavaScript, Java, and most APIs.
  • snake_case: Words joined with underscores. Common in Python, Ruby, and database column names.
  • kebab-case: Words joined with hyphens. Standard for CSS class names and URL slugs.
  • PascalCase: Like camelCase but the first letter is also capitalized. Used for class names and components.
