Additional case conversion optionsWhat is a Case Converter?
A case converter transforms text between different capitalization styles — from everyday formats like UPPERCASE and Title Case, to developer-focused naming conventions like camelCase, snake_case, and kebab-case. Rather than manually retyping or hand-editing every letter, a case converter applies the transformation instantly and consistently across the entire text.
This is especially useful when moving text between contexts that expect different conventions: a heading that needs Title Case for a webpage, a variable name that needs camelCase for JavaScript or snake_case for Python, or a title that needs to become a kebab-case URL slug.
This page lets you convert text case online for free, directly in your browser. Type or paste any text, pick a format, and it's converted instantly in place — with Undo and Redo to safely try different formats — nothing is uploaded or sent to a server.
Why Convert Text Case?
Variable & Function Naming
Switch a phrase between camelCase, PascalCase, and snake_case to match your language’s naming convention without retyping it by hand.
Headlines & Titles
Convert a draft heading to Title Case or Sentence case to match a style guide before publishing an article or page.
Data Cleanup
Normalize inconsistently cased data — like names or labels pasted from a spreadsheet — into a single consistent case.
URLs & Slugs
Convert a title into kebab-case or path/case to generate a clean URL slug or file path.
