How does Sentence Case conversion behave?

It automatically capitalizes the first letter of each sentence (after periods, exclamation marks, or question marks) and forces all other letters to lowercase.

Is my copy safe when using this converter?

Yes. The text formatting runs 100% locally on your machine using JavaScript. No contents are uploaded to our servers.

What is the difference between camelCase and snake_case?

camelCase removes spaces and capitalizes the first letter of each word except the first. snake_case replaces spaces with underscores and sets all letters to lowercase. Both are widely used in programming.
