What is the Case Converter?
A case converter changes the capitalization pattern of a block of text without altering the words themselves. The eight common patterns split between writing styles (UPPERCASE, Title Case, Sentence case) and programming conventions (camelCase, PascalCase, snake_case, kebab-case). Picking the right one is faster than retyping.

Frequently Asked Questions
What case formats are supported?
Eight: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case. The first four are for writing; the last four are programming naming conventions for variables, classes, database columns, and CSS classes respectively.
What is the difference between camelCase and PascalCase?
Both join words with no separator and capitalize each subsequent word. The difference is the very first letter: camelCase starts lowercase (myVariableName), PascalCase starts uppercase (MyVariableName). JavaScript variables are typically camelCase; React components and class names are PascalCase.
Can I convert large amounts of text?
Yes. There's no character limit, and conversion runs synchronously in your browser. A novel-length manuscript converts in well under a second.
