Convert Case transforms text between every casing convention you might need — from simple upper and lower through title and sentence case to the programming conventions camelCase, snake_case and kebab-case.
Casing matters more than it looks. Title case follows capitalisation rules that differ by style guide, sentence case needs proper handling of abbreviations, and programming conventions like camelCase and snake_case are tedious to produce by hand across dozens of identifiers.
The tool handles all of these in one place, working in the browser so your text is not uploaded. It is particularly useful when moving between naming conventions — turning a list of database column names into JavaScript variables, for example.
Additional utilities typically include alternate case, inverse case and line-based transforms.
