What is text case conversion?

Text case conversion is the process of transforming text between different formatting styles used in writing and programming. Different cases serve specific purposes: camelCase for JavaScript variables, snake_case for Python functions, CONSTANT_CASE for configuration values, and many others. Each case style follows specific rules about capitalization, word separation, and formatting that make code more readable and conform to language conventions.

Tool description

The Case Converter tool transforms text between multiple case formats commonly used in programming and writing. It supports various naming conventions including camelCase, snake_case, PascalCase, CONSTANT_CASE, and more. The tool automatically converts your input text to the selected case format, making it easy to adapt text to different coding standards and style guides.

Examples

Input: "hello world example"

  • Camel Case: helloWorldExample
  • Pascal Case: HelloWorldExample
  • Snake Case: hello_world_example
  • Constant Case: HELLO_WORLD_EXAMPLE
  • Dot Case: hello.world.example
  • Path Case: hello/world/example
  • Capital Case: Hello World Example
  • Sentence Case: Hello world example

Input: "UserProfileSettings"

  • Camel Case: userProfileSettings
  • Snake Case: user_profile_settings
  • Constant Case: USER_PROFILE_SETTINGS
  • Dot Case: user.profile.settings

Supported Case Formats

  • No Case: Text without any transformations
  • Camel Case: firstWordLowerCaseFollowingUpperCase (common in JavaScript, Java)
  • Pascal Case: FirstWordAndFollowingUpperCase (common in C#, class names)
  • Snake Case: words_separated_by_underscores (common in Python, Ruby)
  • Constant Case: WORDS_SEPARATED_BY_UNDERSCORES_UPPERCASE (for constants)
  • Dot Case: words.separated.by.dots (package names, namespaces)
  • Path Case: words/separated/by/slashes (file paths, URLs)
  • Capital Case: Words Separated By Spaces Capitalized (titles, headers)
  • Sentence Case: First word capitalized rest lowercase (natural language)
