FAQ
What is the difference between PascalCase and snake_case?
PascalCase (Every word begins with a capital letter, with no delimiters or spaces.) is primarily used for Standard for classes, interfaces, and React/Vue component names in C#, TypeScript, Python, Go.. In contrast, snake_case (All words are lowercase, separated by underscores `_`.) is the standard for Standard for variables and functions in Python, Ruby, Rust, and SQL database column names..
Are multi-line inputs supported?
Yes. You can paste lists of variable names, database column names, or JSON keys separated by newlines to convert them all at once.
Is my code private?
Yes, 100% private. All conversions happen entirely in your local web browser using client-side JavaScript. No data is sent to any server.
