About this tool
Convert text between upper, lower, title, sentence, camelCase, PascalCase, snake_case, and kebab-case. Faster than retyping a heading someone sent in caps, and far faster than hand-converting a list of field names between conventions.
Everything runs locally, so it is safe for column names and identifiers you would rather not paste into an unknown site.
Common questions
What is the difference between title case and sentence case?
Title case capitalises most words — "How to Record a Demo". Sentence case capitalises only the first word and proper nouns — "How to record a demo". Most modern product interfaces use sentence case because it reads faster and feels less shouty.
When should I use snake_case versus kebab-case?
snake_case for database columns, Python, and environment variables. kebab-case for URLs, CSS class names, and HTML attributes — hyphens are safe in a URL where underscores are easy to lose under a text underline.
Why does camelCase matter for JSON?
It does not to the parser, but consistency matters to everyone reading it. JavaScript APIs conventionally use camelCase keys; mixing conventions in one payload is a reliable source of subtle bugs where a key is silently undefined.
