About the Case tool
Paste text and click any of the case buttons — UPPER CASE, lower case, Title Case, Sentence case, camelCase or snake_case — then copy the result.
Title Case capitalizes the first letter of each word; Sentence case capitalizes only the first letter of each sentence, which is usually what you want for headings from all-caps source text.
