Clear answers about using this tool and automating workflows with RunMacro.
Title Case capitalizes the first letter of major words while keeping short articles and prepositions lowercase (e.g., "The Art of War"). Sentence case only capitalizes the very first letter of the sentence and proper nouns.
camelCase and snake_case are naming conventions in software development that eliminate spaces. camelCase capitalizes each new word without spaces (used in JavaScript/Java), while snake_case separates words with underscores (standard in Python and SQL).
