FAQ

How does the converter handle acronyms like "API" or "URL"?

The converter recognizes common acronyms and handles them appropriately for each case style. For example, "getAPIResponse" converts to "get_api_response" in snake_case and "get-api-response" in kebab-case, keeping the output consistent and readable.

Can I convert multiple lines at once?

Yes. Each line in the input is treated as a separate item and converted independently. This is useful when you need to rename a list of variables, database columns, or CSS classes in bulk.

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every significant word (e.g., "The Quick Brown Fox"), while Sentence case only capitalizes the first letter of the first word and proper nouns (e.g., "The quick brown fox"). Title Case is common for headings, and Sentence case is typical for body text and UI labels.
