Case Converter
Convert text between uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, and kebab-case.
What is a Case Converter?
A case converter transforms text between different capitalisation formats in a single click, from UPPER CASE to snake_case and everything in between.
Developers need camelCase for variables and kebab-case for URLs. Editors need title case for headlines and sentence case for body copy. Doing these conversions manually is error-prone and slow, especially for longer strings. A case converter handles any length of text in under a second, and all 8 formats are available from the same tool.
