What is a case converter?
A case converter changes the capital and small letters of a text. It fixes a paragraph typed with caps lock on, formats a headline in title case, or turns a phrase into the camelCase or snake_case names programmers use for variables and file names.
Title case keeps small words such as of, the and and in lower case unless they start the title or follow a colon. Sentence case capitalises the first letter of each sentence and the lone word I. Letters without capitals, such as Arabic, are left as they are.

Questions people ask
How do I fix text typed in all capitals?
Paste it and choose Sentence case or lower case. Sentence case also capitalises the start of each sentence.
What is title case?
A style for headlines where the main words start with a capital letter and small words like of, the and and stay in lower case, except at the start.
What is the difference between camelCase and PascalCase?
Both join words without spaces and capitalise each new word. camelCase starts with a small letter (myFileName), PascalCase with a capital (MyFileName).
Does it work with Arabic?
Arabic has no capital letters, so it is left unchanged. Latin words mixed into Arabic text are converted.
