Frequently asked questions

What text cases are available?
UPPERCASE, lowercase, Title Case (capitalize first letters), Sentence case (capitalize first word), camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and more. Each has specific uses in coding and writing.
When should I use each case style?
lowercase: CSS classes, URLs. UPPERCASE: constants, emphasis. Title Case: headings, titles. camelCase: JavaScript variables. PascalCase: class names, React components. snake_case: Python, database columns. kebab-case: URLs, CSS, HTML attributes.
How do I convert between programming case styles?
Paste your identifier (myVariableName), and convert to any other case (my_variable_name, my-variable-name, MY_VARIABLE_NAME). The tool recognizes word boundaries in all common formats and converts correctly.
What is title case vs. sentence case?
Title Case Capitalizes Most Words Like This. Sentence case capitalizes only the first word and proper nouns. Style guides differ on title case rules (which small words to lowercase). Our tool follows common conventions.
How are special characters handled?
Letters are converted; numbers and most special characters are preserved. For code identifiers, underscores and hyphens serve as word separators. Unicode letters (accented characters, etc.) are handled correctly in most cases.
