Frequently Asked Questions

  • Title Case capitalizes the first letter of every word in the text. For example, "hello world" becomes "Hello World". It is commonly used for headings, titles, and proper nouns.
  • camelCase is a naming convention commonly used in programming languages like JavaScript, Java, and C#. Variable and function names are written by joining words together, with the first word in lowercase and each subsequent word capitalized, like "myVariableName".
  • snake_case uses underscores to separate words (e.g., "my_variable_name") and is common in Python and Ruby. kebab-case uses hyphens (e.g., "my-variable-name") and is commonly used in URLs, CSS class names, and file names.
  • Sentence case capitalizes only the first letter of each sentence, with the rest in lowercase. It detects sentence boundaries using periods, exclamation marks, and question marks.
  • Yes. Numbers and special characters remain unchanged during case conversion. Only alphabetic characters are affected by the case transformations.
