What is a Case Converter?

A case converter changes the capitalization of text. It's useful for fixing text that was accidentally typed in the wrong case, formatting headlines, creating variable names for programming, or converting between different naming conventions. This tool supports 12 different case formats including standard text formats and developer-specific ones like camelCase, snake_case, and kebab-case.

Frequently Asked Questions

Sentence case, lowercase, UPPERCASE, Title Case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case, and aLtErNaTiNg case.
Does it work with any language?
It works best with English and Latin-based languages. Some case conversions like title case may not work perfectly with non-Latin scripts.
Is my text processed on the server?
No. All conversions happen in your browser using JavaScript. Your text is never sent to any server.
What is sentence case?
Sentence case capitalizes the first letter of each sentence and lowercases everything else. It's the standard for most body text.
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (e.g. myVariableName). PascalCase starts with an uppercase letter (e.g. MyVariableName). Both are used in programming.
