FAQ
What is the difference between camelCase and snake_case?
camelCase joins multiple words together with the first word lowercase and each subsequent word capitalized, like myVariableName. snake_case uses all lowercase letters connected by underscores, like my_variable_name. camelCase is commonly used in JavaScript/TypeScript, while snake_case is popular in Python and database column names.
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word (e.g. The Quick Brown Fox), suitable for headings. Sentence case only capitalizes the first letter of each sentence (e.g. The quick brown fox.), suitable for body text.
Does this tool support non-English text?
This tool is primarily designed for English letter case conversion. Non-Latin characters (such as Chinese) do not have case distinctions, but you can still use the tool with mixed text — it will correctly convert the English portions while leaving other characters unchanged.
