About Case Converter
Text appears in different cases in different contexts — variable names use camelCase or snake_case in code, titles use Title Case, constants use UPPERCASE, and URLs prefer kebab-case. Converting between these manually is tedious and error-prone for anything longer than a sentence. This case converter handles all the common formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, dot.case, and more.
Day to day this saves time when refactoring variable names across a codebase, generating SEO-friendly URL slugs from page titles, formatting headings for consistency, and normalizing user-submitted text. It handles multi-word inputs intelligently and respects existing word boundaries, so converting back and forth between formats is lossless.

Frequently Asked Questions

camelCase starts with a lowercase letter (helloWorld), while PascalCase starts with an uppercase letter (HelloWorld). Both are commonly used in programming.
When should I use snake_case vs kebab-case?
snake_case (hello_world) is common in Python, Ruby, and database columns. kebab-case (hello-world) is used in URLs, CSS class names, and file names.
What is alternating case?
